Nearsightedness Boosts Risks for Glaucoma
Roughly one-third of all adults in the United States are nearsighted, needing some type of visual correction. Technically labeled myopia, nearsightedness is a condition in which objects that are near can be clearly seen, while objects further away appear blurry. With a tendency to run in families, the development of myopia can be gradual or rapid, and it often worsens during childhood and adolescence.
While nearsightedness is easily correctible with eyeglasses, contact lenses or LASIK surgery - a new concern has popped up for individuals with myopia.According to a recent study, nearsighted people may be more likely to develop glaucoma which is a leading cause of blindness. Individuals who are concerned about maintaining optimum vision may benefit from taking vitamins designed to specifically support eye health.
The study which was published in the journal, Ophthalmology, looked at data from eleven prior eye studies. It was determined that risks for glaucoma were roughly 90% higher in people with myopia as compared to people who didn?t have myopia. It is important to note however, that the results showed that nearsightedness and glaucoma occur together, but did not show that one causes the other.
Experts don?t yet understand why the two conditions occur together, but one theory suggests that it could have something to do with the shape of myopic eyes which are more oval than round It could also be that the conditions run in families together.
Over two million people in the United States have been diagnosed with glaucoma which the National Institutes of Health have defined as a group of eye conditions that can ultimately damage the optic nerve, resulting in vision loss. Although there are several types of treatment for glaucoma, none can restore vision once it is lost.
Like most diseases, the earlier glaucoma is caught, the greater the chances of preventing progression of the disease, and in this case, loss of vision.Therefore it is wise to have regular eye exams. Here are some other great tips for good eye care:
- Keep health conditions like diabetes and high blood pressure in check.
- Learn to recognize symptoms that could indicate a retinal tear or detachment: blurry vision, sudden loss of vision in one eye, light flashes or halos around light. Immediately contact your health provider if any of these symptoms are present.
- Protect eyes from the sun?s rays. Wear UVA and UVB sunglasses especially if you spend a good amount of time in the sun.
- Eat foods that benefit good eye health like carrots, leafy greens and wild-caught fish.
- Don?t smoke, and drink alcohol in moderation.
- Utilize good lighting for optimum vision.
