Tips on healthy vision

More than 20 million Americans suffer from severe vision loss. While not all eye diseases can be prevented, there are simple steps that everyone can take to help their eyes remain healthy now and reduce their chances of vision loss in the future.

Proper care and caution is very important to prevent serious eye diseases and possible blindness. Something as simple as remembering to wear your sunglasses can delay the development of cataracts.

Here are the top 10 tips to safeguard your vision:

Wear sunglasses - UV blocking sunglasses delay the development of cataracts, since direct sunlight hastens their formation. Sunglasses prevent retinal damage; they also protect the delicate eyelid skin to prevent both wrinkles and skin cancer around the eye, and both cancerous and non-cancerous growths on the eye. The U.S. standard states that the lenses should have a UVB (280 to 315nm) transmittance of no more than one percent and a UVA (315 to 380nm) transmittance of no more than 0.5 times of the visual light transmittance.

Don’t smoke - Tobacco smoking is directly linked to many adverse health effects, including age-related macular degeneration (AMD). Studies show that current smokers and ex-smokers are more likely to develop AMD than people who have never smoked. Smokers are also at increased risk for developing cataracts.

Eat right - Vitamin deficiency can impair retinal function. The belief that eating carrots improves vision has some truth, but a variety of vegetables, especially leafy green ones, should be an important part of your diet. Researchers have found people on diets with higher levels of vitamins C and E, zinc, lutein, zeaxanthin, omega-3 fatty acids DHA and EPA are less likely to develop early and advanced AMD.

Baseline eye exam - Adults with no signs or risk factors for eye disease should get a baseline eye disease screening at age 40—the time when early signs of disease and changes in vision may start to occur. Based on the results of the initial screening, an ophthalmologist will prescribe the necessary intervals for follow-up exams. Anyone with symptoms or a family history of eye disease, diabetes or high blood pressure should see an ophthalmologist to determine how frequently your eyes should be examined.

Eye protection - An estimated 2.5 million eye injuries occur in the U.S. each year, so it is critical to wear proper eye protection to avoid eye injuries during sports such as hockey and baseball and home projects such as home repairs, gardening, and cleaning. For most repair projects and activities around the home, standard ANSI-approved protective eyewear will be sufficient. Sports eye protection should meet the specific requirements of that sport; these requirements are usually established and certified by the sport’s governing body and/or the American Society for Testing and Materials (ASTM).

Know your family history - Many eye diseases cluster in families, so you should know your family’s history of eye disease because you may be at increased risk. Age-related eye diseases, including cataracts, diabetic retinopathy, glaucoma and age-related macular degeneration are expected to dramatically increase—from 28 million today to 43 million by the year 2020.

Early intervention - Most serious eye conditions, such as glaucoma and AMD, are more easily and successfully treated if diagnosed and treated early. Left untreated, these diseases can cause serious vision loss and blindness. Early intervention now will prevent vision loss later.

Know your eye care provider - When you go to get your eyes checked, there are a variety of eye care providers you might see. Ophthalmologists, optometrists and opticians all play an important role in providing eye care services to consumers. However, each has a different level of training and expertise. Make sure you are seeing the right provider for your condition or treatment. Ophthalmologists are specially trained to provide the full spectrum of eye care, from prescribing glasses and contact lenses to complex and delicate eye surgery.

Contact lens care - Follow your Eye M.D.’s instructions regarding the care and use of contact lenses. Abuse, such as sleeping in contacts that are not approved for overnight wear, using saliva or water as a wetting solution, using expired solutions, and using disposable contact lenses beyond their wear can result in corneal ulcers, severe pain and even vision loss.

Be aware of eye fatigue - If your eyes are tired from working at a computer or doing close work, you can follow the 20-20-20 rule: Look up from your work every 20 minutes at an object 20 feet away for 20 seconds. If eye fatigue persists, it can be a sign of several different conditions, such as dry eye, presbyopia, or spectacles with lenses that are not properly centered.
