Some people are born with poor eyesight, while others develop poor eyesight when they are young. Almost everyone experiences some deterioration in their eyesight as they age. How can you stop your vision from getting worse?
In today’s health-conscious society, the prevalent theory is that proper nutrition will slow down, and perhaps even improve, deteriorating vision. While studies have not proved this to be 100 percent effective, it certainly does no harm to one’s vision and definitely improves health.
Foods important to good vision are high in fiber and in vitamins such as C, D, and beta carotene or Vitamin A. Examples of such foods are carrots, spinach, kale, broccoli, raw cabbage, cauliflower, grapes, blueberries, bilberries, and cranberries. Sunflower seeds, flax seeds, and almonds are also good sources.
Egg yolks are a good source of lutein and zeaxanthin, both of which are thought to be beneficial in protecting vision and slowing macular degeneration, which is the leading cause of poor vision and blindness in elderly people
Omega-3 fatty acids are also essential to eye health. They’re found in supplements and fatty fish like Atlantic mackerel, herring, salmon, rainbow trout, tuna, and sardines. Omega-3s have many health benefits ranging from lowering cholesterol and blood sugar, to reducing the risk of macular degeneration.
Many medical procedures have been developed to stop vision from deteriorating once a diagnosis has been made.
Laser eye surgery may not only prevent vision from continuing to deteriorate in certain individuals, it may correct the existing vision problem so that they no longer need contact lenses or glasses. There are different types of laser eye surgery, with LASIK (laser assisted in situ keratomileusis) being the most common type. This involves reshaping the cornea to change its focusing power. The success of this type of surgery depends on the underlying cause of the vision problem and not everyone is a candidate for such procedures.
Cataract surgery is a common procedure that more than half of the people in the US over the age of 80 have received. Cataracts form over the lens of the eye causing the vision to cloud. They usually develop slowly and can be helped in the beginning stages with new glasses, brighter lighting, or anti-glare sunglasses. Surgery involves removing the cloudy lens and replacing it with an artificial lens.
For most people correcting vision is as simple as seeing a qualified optometrist and getting a prescription for contact lenses or glasses.
Contact lenses have become popular for many reasons. Some people don’t like the way they look in glasses, or find them cumbersome depending on their lifestyle. Contact lenses are also available in many different colors that allow the wearer to change their eye color or even the appearance of their eyes if they choose cosmetic lenses. Contact lenses should be fitted properly to avoid injuring the eye, and care must be taken to avoid infection.
Eyeglasses are the most common option for improving vision and, in some cases, stopping it from deteriorating. Eyeglasses come in two parts, the lens, which is where the prescription from the eye doctor comes in, and the frame, which the wearer usually gets to choose. Lenses may be made of glass or plastic. Thickness is determined by the strength of the prescription. Most people with very poor vision choose plastic lenses because they are lighter than glass. Frames also come in several different styles, colors and may be plastic or metal, and costs vary greatly according to the options chosen.
