Eye Doctors Weigh In: How Smoking Can Harm Your Vision & Eye Health

We all know that smoking is bad for you, especially the risks that it poses to your heart and lungs. What many people do not know is that cigarette smoke negatively affects your eyes and vision too. As our eye doctor can explain during your next eye exam, smoking has been directly linked to an increase in the risks of both cataracts and macular degeneration, two leading causes of vision loss, and it is believed to be a factor in a number of other eye and vision issues.

Smoking and Cataracts

Studies show that smoking doubles the risk of cataracts and with heavy smoking, the risk triples. In fact, there seems to be a direct correlation between the amount of smoking and the likelihood of cataracts. Cataracts are characterised by the clouding of the lens of the eye and it is believed that smoking affects the cells of the lens, accelerating this process.

Cataracts are a leading cause of vision loss worldwide, however they can be treated surgically by removing the clouded lens and replacing it with an artificial one. Symptoms include:

• • Blurred, cloudy or dim vision
  • Sensitivity to light and glare
  • Presence of halos around lights
  • Increasingly poor night vision
  • Fading color vision
  • Double vision
  • and frequent prescription changes with minimal improvement in vision

Smoking and Age-Related Macular Degeneration

According to medical research, smoking increases the likelihood of developing age-related macular degeneration between two and four times the normal risk – the more you smoke, the greater the risk. Unfortunately, there is also an increased risk for those exposed to cigarette smoke for extended periods of time.

Age-related macular degeneration or AMD is a condition in which the macula, which is the center of the retina, begins to to deteriorate, reducing central vision and the eye’s ability to see fine details. The disease is characterized by blurred and distorted eyesight and blind spots in the central vision. With time, the disease can progress to leave the person with low vision, which is significant vision loss that cannot be corrected by eyeglasses, contact lenses or refractive surgery.

Other Eye and Vision Risks of Smoking

Smoking has also been linked to dry eyes, optic nerve damage and diabetic retinopathy (for those with diabetes).

“Eye Vitamins” are often used without doctor’s recommendations. Smokers are cautioned not to take beta-carotene supplements, specifically, (or multi-vitamins containing this ingredient) as studies indicate there is increased risk of cancer even in people who quit smoking.

What to Do?

Even if you have been smoking for years, quitting will reduce the risks of developing these conditions, for yourself and those around you. If you do smoke, make sure to schedule a comprehensive eye exam every year to catch any developing disease early. Early diagnosis and treatment can be the key to saving your vision and preventing permanent vision loss.

In an effort to spread the word to increase awareness about Sjogren’s Disease, eye care providers are speaking out about this hard-to-diagnose condition.

As our eye doctor can explain during your next eye exam, Sjogren’s is a systemic autoimmune disorder that can affect the whole body. One of the primary symptoms is excessive dryness particularly in the eyes and mouth. Other serious symptoms include chronic fatigue and pain, specifically in the joints, as well as major organ dysfunction. The syndrome also increases chances of neuropathies and lymphomas.

The severity of the disease varies greatly, ranging from mild discomfort to debilitating symptoms that can seriously impair normal functioning in everyday life. Early diagnosis and treatment can prevent serious complications and improve quality of life. There is currently no cure for Sjogren’s, yet there are treatments for many of the individual symptoms. On average patients are prescribed upwards of 8 medications to treat the wide range of symptoms.

Women are nine times more likely to develop Sjogren’s than men and diagnosis usually occurs around the age of 40. Unfortunately, because the symptoms vary from person to person, and the disease often occurs in the presence of or mimics other diseases (such as lupus, rheumatoid arthritis, menopause, allergies or multiple sclerosis) the disease is often misdiagnosed or overlooked. Further, because the symptoms can affect different parts of the body system such as the teeth, eyes or musculoskeletal system, various health professionals are sought to diagnose or treat specific symptoms (such as rheumatologists, dentists or eye doctors) while the big picture is often missed. On average it takes almost three years to obtain a Sjogren’s diagnosis once symptoms are noticed.

Since dry eye is one of the most common early symptoms of the disease, there has been an effort to educate eye care providers to recognize and to be aware to look for symptoms of the disease. Patients also need to be aware and proactive about speaking to their health care providers about potential diagnosis and treatment. Knowing the risk factors and symptoms can be imperative to a faster diagnosis.

Your eye doctor may be able to detect and diagnose Sjogren’s syndrome from dry eye symptoms as well as other diagnostic tests and review of symptoms. With this diagnosis the treatment will be different from typical dry eye disease. Since it is an autoimmune disease, lubricating eye drops may provide temporary relief but will not address the source of the problem. Your doctor may prescribe newer cyclosporine drops as well to treat the inflammatory response. If you have dry eyes and typical treatments aren’t working, it may be worthwhile to ask about Sjogren’s.

Sjogren’s patients often feel misunderstood because most of the debilitating symptoms are not visible to others and the disease is often not recognized largely due to a lack of awareness. By increasing both public and professional awareness, the goal is to reduce diagnosis time and to advance research on the cure for this disorder.

Hey women! Did you know that women are more likely to suffer from vision problems and are at higher risk of permanent vision loss than men? Well 91% of the women surveyed recently didn’t know that, which means that many of them aren’t taking the necessary precautions to prevent eye damage and vision loss.

According to a recent study, the statistics for many of the major vision problems show that women have a higher percentage of incidence than men. These include:

• Age-related Macular Degeneration 65%
• Cataracts 61%
• Glaucoma 61%
• Refractive Error 56%
• Vision Impairment 63%

As our eye doctor can explain during your next eye exam, women are also more susceptible to develop chronic dry eye, partially because it is often associated with other health issues that are more common in women such as ocular rosacea which is three times more prevalent in women. Hormonal changes during pregnancy and menopause can also contribute to dry eye.

It’s important for women to know the risks for eye-related diseases and vision impairment and the steps they can take to prevent eventual vision loss. Here are some ways that you can help to protect your eyes and save your eyesight:

• Find out about family history of eye diseases and conditions.
• Protect your eyes from the sun by wearing 100% UV blocking sunglasses when outdoors.
• Don’t smoke.
• Consume a healthy diet with proper nutrition and special eye health supplements as prescribed by an eye doctor.
• Adhere to contact lens hygiene and safety.
• Adhere to cosmetic hygiene and safety precautions.
• Protect your eyes against extended exposure to blue light from computers, smartphones and LED lamps.
• If you are pregnant or planning to become pregnant and have diabetes, see an eye doctor for a comprehensive eye exam. In women who have diabetes, diabetic retinopathy can accelerate quickly during pregnancy and can present a risk for the baby as well.

Mothers are often charged with caring for the eye health of the entire family, but too often their own eye health needs fall to the wayside. It is critical that mothers take care of their eyes and overall health so that they can be in the best condition to care for their families.

Speak to your eye care professional about your personal eye health and vision risks and the precautions and measures you should take to protect your eyes. Encourage the other women in your life to do so as well. Once vision is lost, it often can’t be regained and there are many steps you can take to prevent it with proper knowledge and awareness.

The most important way to prevent vision loss is to ensure you schedule regular eye exams. Don’t wait for symptoms to appear as many eye issues are painless and symptomless, and sometimes by the time you notice symptoms, vision loss is untreatable.

There is nothing worse than a dirty spot on your glasses – well except perhaps many dirty spots or smudges. When that happens, most of us are tempted to grab the corner of our shirt and wipe it off, but resist the temptation – this is actually not a good idea.

As our eye doctor can explain during your next eye exam, there is a right way and a wrong way to clean your glasses. Cleaning your glasses properly will not only remove irritating dirt and smudges, but will also prevent your lenses from getting scratched allowing you to see your best.

You want to make sure that the materials you use to clean your lenses are clean and soft. The reason your shirt corner is not the best option is because it likely contains dust or particles that can scratch your lens. However, you don’t need fancy, lens cleaners either. In truth the best cleaner for your glasses may be more simple than you expect –

Gentle Dish Soap

That’s right, a gentle dish soap, warm water and a clean, dry soft cotton towel are the best tools you can have for cleaning your lenses.

Simply rinse your glasses in warm water and apply a small drop of soap (make sure to use a brand of soap that is lotion and moisturizer free). Rub the soap into the lens with your fingers and rinse thoroughly until all of the soap has been removed. Gently shake the glasses to remove excess water and then dry with a clean, dry, lint-free towel.

You may be wondering about the microfiber lens cloths and spray cleaner you get from your optician. These lens cleaning packs are great for when you are on the go and don’t have access to a sink and dish soap. The microfiber cloths are also great for polishing dry lenses after any dust or particles are blown away- just make sure they are cleaned regularly. For a real, thorough clean however, we advise that you use the technique above.

Cleaning Don’ts

Don’t use vinegar, glass or window cleaner, bleach, ammonia or spit/saliva for cleaning your lenses. The chemicals could strip off the coatings on your lenses, and saliva – well, it just doesn’t work. In particular, many lenses these days have anti-glare treatments that are especially prone to damage if not cleaned properly and are particularly vulnerable to window cleaners and alcohol.

Remember once your glasses are scratched, there is little to do to repair them. If you see something on your lens try to blow or brush it away carefully before you use a cloth to clean your lenses.

Keeping Your Lenses Clean

To avoid dirt and smudges, always take your glasses off with two hands using the arms of the frame and avoid touching the lenses. Further, the best way to preserve your glasses and keep them clean is to keep them in a case when they are not in use. It’s worthwhile to get an extra case or two to have on hand in the car or in your purse for times that you need to take your glasses off. If you notice swirled or circular scratches on your lenses, those are almost always from improper cleaning so make sure to take the time to clean them properly the next time.

 

Blue light. Do you know what it is? Do you know where it comes from, or how it can be harmful to your eyes? If you don’t know the answers to these questions, you are not alone, yet it is important that you become aware to protect your eyes for now and the years to come.

As our eye doctor can explain during your next eye exam, the reason blue light is suddenly becoming a big issue is because other than the sun, which is the biggest source of blue light, a significant source of blue light emission comes from digital devices and artificial lighting. As our world becomes increasingly digital – think: HD televisions, LED lights, computers, smartphones, tablets – we are all exposing our eyes to more and more amounts of blue light than ever before. And we are only beginning to understand the long term effects this has on our bodies and our eyes.

One of the biggest issues with blue light is that whether it is through work or leisure, people are exposed to screens at a close range for a large portion of the day. A survey from the Vision Council entitled, “Blue Light Exposure and Digital Eye Strain” recently showed that 87% of respondents used digital devices for more than two hours a day and over 52% regularly used two digital devices as the same time. This shift has drastically increased exposure and the number of symptoms that are reported. To date, research has shown that there are a number of ways blue light can impact your eyes including digital eye strain and sleep disturbances.

Digital eye strain is a condition that is characterized by dry, sore, tired or burning eyes, eye fatigue and sensitivity to light. It can also cause blurred or double vision, headaches, back, neck and shoulder aches and difficulty focusing or concentrating. These symptoms are most common in individuals that sit in front of the computer for two or more hours a day.

Studies show that exposure to blue light right before bedtime can cause disruptions in sleep and wakefulness because it causes a shift in the levels of melatonin, a hormone which affects your circadian rhythm and therefore your sleep patterns. So if you are using your smartphone to wind down in bed, put it down and dust off an old hardcover book!

Despite these risks, few people are taking action to protect their eyes from blue light. A recent study from Transitions Optical, The 2017 Employee Perceptions of Vision Benefits Survey, showed that there is also a significant generational difference in knowledge, habits, and attitude regarding blue light with millennials being more aware and concerned about the health effects it has on their eyes. Millennials are more likely to request prescription eyewear that has blue light protection and to know whether their current pair has that extra coverage. However, even the millennial generation is significantly lacking in awareness and prevention.

The best way to gain awareness of and protection against blue light is to speak to your eye doctor. There are a number of ways you can protect your eyes which include computer glasses, blue light lens filters, or even blue light filter screen protectors or apps that reverse screen colours for those that don’t use prescription eyewear. Each individual can find the best solution based on lifestyle, work environment and personal comfort. The most important takeaway is that you understand that blue light is an issue, take responsibility for your eye health and speak to your eye doctor about the best blue light solutions for you and your family.

 

Age-related macular degeneration is a serious condition that can threaten your vision and general well-being. Characterized by the deterioration of the central area of the retina called the macula which is responsible for focused vision, the disease gradually reduces your central vision. This affects the ability to see fine details, recognize faces, read, drive, watch television and even use a computer. The disease often leaves some vision resulting in a condition called low vision, which is considered a form of legal blindness.

AMD is the leading cause of vision loss in the older population and the numbers are expected to increase as Americans and Canadians continue to live longer.

What causes AMD and how can it be prevented?

As you can see by the name, the primary risk factor of AMD is age, particularly over age 50. Caucasian women are the most common demographic to be hit with this ocular disease; family medical history and having lighter colored hair, skin and eyes play a large role as well. However, several lifestyle factors have been shown to cause an increase in AMD development; so there may be ways to reduce your risk, even if you have a genetic predisposition.

In fact, most of the controllable risk factors pose general health risks that cause a plethora of health issues, so addressing them will boost your overall health and wellness, in addition to protecting your eyes and vision from AMD. Here are 6 ways to prevent AMD and the vision loss that accompanies it:

1. Stop Smoking

Smoking, and even living with a smoker, have been shown to significantly increase your risks of developing AMD to between 2-5 times the risk of non-smokers! If you also have a hereditary risk, smoking compounds that risk tremendously.

2. Get Active

Studies show that obesity and a sedentary lifestyle increase the risk of advanced macular degeneration that leads to significant vision loss. Maintaining a healthy weight and being active can reduce your risk. That could be as easy as regular walking, at least 3 times a week for 30 minutes.

3. Control Blood Pressure

Since the eye contains many tiny blood vessels, high blood pressure can have a serious impact on the health of your eyes. Have your blood pressure checked by our eye doctor during your next eye exam and follow any medical advice you are given to reduce high blood pressure, whether that includes diet, exercise or medication.

4. Choose a Healthy Diet

A diet rich in antioxidants has been shown to protect against AMD. Antioxidants can be found in abundance in dark green leafy vegetables such as spinach, broccoli, kale and collard greens, as well as orange fruits and vegetables such as peppers, oranges, mango and cantaloupe. Eating a wide range of fresh fruits and vegetables, 5-9 servings a day, as well as fish, which contain Omega-3, and avoiding sugar and processed foods will help to keep your body healthy in many ways, including reducing your risk of AMD.

5. Use UV and Blue Light Protection

Long-term exposure to UV rays from the sun and blue light. Make sure you wear sunglasses every time you are exposed to sunlight.

6. Take Supplements*

Certain nutritional supplements have been shown to slow the progression of AMD and the vision loss that accompanies it. This formula of supplements was developed from a 10 year study of 3,500 people with AMD called the Age-Related Eye Disease Study (AREDS) and its successor AREDS2. It is not recommended to take supplementation as a preventative measure but rather only if you are diagnosed with intermediate or advanced AMD.

*Speak to your eye doctor before you make a decision about this option.

During your yearly comprehensive eye exam, your eye doctor will screen for early signs of AMD and recommend treatment if it’s detected. If you’re at greater risk – because of your age or a family history of AMD / blindness of unknown cause, for example – additional testing may be necessary.

AMD can be a devastating disease. If you are aware that you are at risk, it is worthwhile to do everything you can to prevent it and the vision loss that it can bring. Take the time to understand AMD and do what it takes to lower your chances of knowing its effects first-hand.

Your toddler may show every sign of good eyesight including the ability to see objects in the distance, however that doesn’t necessarily mean that he or she doesn’t have a vision problem.

Amblyopia is one common eye condition that is often hidden behind the appearance of good eyesight.

Also known as “lazy eye” it usually occurs when the brain begins to ignore the signals sent by one eye, often because that eye is weaker and doesn’t focus properly. Sometimes it can occur in both eyes, in which case it’s called bilateral amblyopia. This eye condition is especially common in preemies, and tends to run in families as well, so it’s important to provide our eye doctor with a complete medical and family history during your next eye exam.

There are several factors that can cause amblyopia to develop. These include:

• astigmatism
• high nearsightedness or farsightedness
• uneven eye development as an infant
• congenital cataract (clouding of the lens of the eye)
• strabismus (where the eyes are misaligned or “cross-eyed”).

However in many cases of amblyopia there may be no obvious visible structural differences in the eye. In addition to the fact that the eyes may look normal, vision often appears fine as the brain is able to compensate for the weaker eye by favoring the stronger one. Because of this, many children live with their eye condition for years before it is diagnosed. Unfortunately, as a person ages, the brain loses some of its plasticity (how easy it is to train the brain to develop new skills), making it much harder – if not impossible – to treat amblyopia in older children and adults. That’s why it’s so important for infants and young children to have a thorough eye exam.

Are There Any Signs of Amblyopia?

If you notice your child appears cross-eyed, that would be an indication that it’s time for a comprehensive eye exam to screen for strabismus and amblyopia development.

Preschoolers with amblyopia sometimes show signs of unusual posture when playing, such as head tilting, clumsiness or viewing things abnormally close.

However, often there are no signs or symptoms. The child typically does not complain, as he or she does not know what normal vision should look like. Sometimes the condition is picked up once children begin reading if have difficulty focusing on the close text. The school nurse may suggest an eye exam to confirm or rule out amblyopia following a standard vision test on each eye, though it might be possible to pass a vision screening test and still have amblyopia. Only an eye doctor can make a definitive diagnosis of the eye condition.

So How Do You Know If or When To Book a Pediatric Eye Exam?

Comprehensive eye and vision exams should be performed on children at an early age. That way, hidden eye conditions would be diagnosed while they’re still more easily treatable. An eye exam is recommended at 6 months of age and then again at 3 years old and before entering first grade. The eye doctor may need to use eye drops to dilate the pupils to confirm a child’s true refractive error and diagnose an eye condition such as amblyopia.

Treatment for Amblyopia

Glasses alone will not completely correct vision with amblyopia in most cases, because the brain has learned to process images from the weak eye or eyes as blurred images, and ignore them. There are several non-surgical treatment options for amblyopia. While your child may never achieve 20/20 vision as an outcome of the treatment and may need some prescription glasses or contact lenses, there are options that can significantly improve visual acuity.

Patch or Drops

In order to improve vision, one needs to retrain the brain to receive a clear image from the weak eye or eyes. In the case of unilateral amblyopia (one eye is weaker than the other), this usually involves treating the normal eye with a patch or drops to force the brain to depend on the weak eye. This re-establishes the eye-brain connection with the weaker one and strengthens vision in that eye. If a child has bilateral amblyopia, treatment involves a regimen of constantly wearing glasses and/or contact lenses with continual observation over time.

Your eye doctor will prescribe the number of waking hours that patching is needed based on the visual acuity in your child’s weak eye; however, the periods of time that you chose to enforce wearing the patch may be flexible. During patching the child typically does a fun activity requiring hand eye coordination to stimulate visual development (such as a favorite video game, puzzle, maze etc) as passive activity is not as effective.

The earlier treatment starts, the better the chances are of stopping or reversing the negative patterns formed in the brain that harm vision. Amblyopia treatment with patches or drops may be minimally effective in improving vision as late as the early teen years (up to age 14) but better results are seen in younger patients.

Vision Therapy

Many optometrists recommend vision therapy to train the eyes using exercises that strengthen the eye-brain connection. While success rates tend to be better in children, optometrists have also seen improvements using this occupational therapy type program to treat amblyopia in adults.

The key to improvement through any non-surgical treatment for amblyopia is compliance. Vision therapy exercises must be practiced on a regular basis. Children that are using glasses or contact lenses for treatment, must wear them consistently. Your eye doctor will recommend the schedule of the patching, drops, or vision therapy eye exercise and the best course of treatment.

Amblyopia: Take-home Message

Even if your child is not showing any signs of vision problems, and especially if they are, it is important to have an eye examination with an eye doctor as soon as possible, and on a regular basis. While the eyes are still young and developing, diagnosis and treatment of eye conditions such as amblyopia are greatly improved.
