Smartphones and Sun Exposure Can Speed Up Macular Degeneration
A new study claims that blue light emitted from digital devices, including smartphones and tablets, may lead to macular degeneration. Macular degeneration is an incurable eye disease that leads to significant vision loss in people age 50 or older and the leading cause of blindness in the U.S.
While this study makes a connection between blue light and vision loss later in life, more research is needed to determine how much natural and man-made blue light is "too much."
According to the Vision Council, nearly one-third of adults spend more than half their waking hours using a digital device. Even more alarming, nearly 32% of adults do not take any action to reduce digital eye strain.
According to this study, repeated exposure to blue light and the sun can cause retinal molecules to trigger reactions in the eye, which generate poisonous chemical molecules in photoreceptor cells and kills them. These cells do not regenerate.
A condition associated with blue light exposure is Computer Vision Syndrome (CVS). CVS manifests through fatigue, headaches, blurred vision and other non-specific symptoms. Researchers also found when people use digital devices in the evening, it increases the prevalence of sleep disorders.
Fortunately, sunglasses or other task-specific eyewear that filter UV and blue light can protect the eyes. If selecting blue light-blocking lenses, be aware that most varieties distort color perception.
DuraVision BlueProtect by ZEISS Vision Care offers an exceptional anti-reflective coating with excellent light transmission that deflects the most harmful wavelengths without interfering with the body’s circadian rhythm, your natural sleep/wake cycle.
Visit your ophthalmologist for a comprehensive eye exam to evaluate your symptoms and an optical expert to fill your prescription for the appropriate task specific eyewear.

Shedding Light on Nighttime Driving Glasses
With this month’s look at task-specific eyewear, we’ll be discussing glare-reducing driving glasses and how they can help motorists combat distracting light glare and unwanted strain.
A recent survey confirmed what most of us already know – nighttime glare decreases vision and causes discomfort. About a third of respondents experienced difficulty visualizing road signs and judging distances, the study noted. Over half said headlights were particularly bothersome while 50% experienced glare and light sensitivity.
The most common cause of night driving problems is the need for glasses. Improving clarity obviously enhances safety on the road. Glasses containing a high-quality anti-reflective (AR) coating substantially reduces glare and haloes. Our optical staff at Classic Eyewear strongly encourages the use of AR coating for all our patients’ eyewear.
There are several other causes of nighttime difficulty, the most common of which is cataracts. Even mild cataracts which otherwise are not bothersome can cause very significant glare and haloes while night driving. As cataracts progress, many people stop driving altogether. Cataract surgery promptly relieves this problem and, of course, improves vision for reading, television watching and all other activities.
Another common cause of nighttime vision problems is Dry Eye Disease. By disturbing the surface of the eye, vision decreases and glare increases. Prompt treatment of this disorder not only improves vision, both night and day, but also improves the discomfort and pain that often occurs in dry eye sufferers.
Safely reaching your destination is always our goal. The doctors and staff of the Coastal Jersey Eye Center are here to help you stay sharp behind the wheel!

Do You Stare at a Screen All Day? If So, Here’s How To Protect Your Eyes
All of us use computers, tablets and smartphones all day, every day. A recent survey put the number at five hours a day. The Census Bureau reported in 2015 that a whopping 87% of American households possess a computer. No wonder that record numbers of Americans complain of eye problems due to computer use.
Computer Vision Syndrome (CVS, not to be confused with the more famous CVS pharmacy chain) is a fancy name for eyestrain when using digital devices. Symptoms include some combination of headache, fatigue, irritation, scratchiness, dryness and blurring. At greatest risk for developing CVS are individuals who spend two or more continuous hours at a computer or mobile device every day.
Computer and mobile device use is different than reading a printed page. The print is not as precise or sharply defined, the level of contrast between the letters and the background is reduced and the presence of glare and reflections on the screen may make viewing difficult. Viewing distances and angles are different compared to book and newspaper reading. These factors place additional demands on the visual system.
Uncorrected or under corrected needs for glasses will worsen significantly all the problems noted above. We strongly encourage a thorough eye examination in CVS sufferers for this reason. Anti-reflective coatings in glasses will reduce glare from the various screens in use today.
Dry Eye Disease (DED) is also a significant contributor to CVS. Previous articles discussing DED are available at www.coastaljerseyeye.com/blog (Feb. 2018 and Jan. 2017).
Classic Eyewear is located in our Linwood (927-4424) and Cape May Court House (465-7926) offices. Our optical experts are available to fill your prescription for computer glasses or other task specific eyewear. With digital screens a part of everyday life, working with computers should be as comfortable and enjoyable of an experience as it is productive!
