Life is a Blur with Defective Vision
Vision is a sense that everyone needs in order to function on a day to day basis, but not all of us are blessed with 20 – 20 sight. There are many vision defects that may make a person see life through blurry eyes. Fortunately, ophthalmology has also advanced enough that there are solutions to most all of these problems. These solutions give people who suffer from defective vision a chance to see life through a new lens—literally.
Causes of Defective Vision
Sadly, not all defective vision is caused simply by easily avoidable issues like abuse on the eyes. There are many cases of defective vision in which the person was simply born with the issue. At times, a person’s eyesight depends on genes. It’s possible as well that there are certain internal factors in a person’s physiology such as bad blood circulation as well as nerve supply.
However, there are also a number of external factors such as lifestyles and activities that can make a difference in a person’s vision. Activities like excessive reading, continuous computer use, too much television and not getting enough sleep can cause some problems with vision. Having an improper diet can affect vision as well. Constant strain on the eyes can usually cause vision problems in the long run.
Kinds of Defective Vision
There are several common eye defects that people have to deal with. One of these problems is astigmatism, where a person’s vision blurs because of a variation on the cornea’s shape. Light does not enter the eyes at the same point because the vertical and horizontal planes of the cornea do not meet at the same point. Vision becomes more blurred as the planes are more uneven.
Myopia is the condition of short-sightedness, where objects in a distance appear blurred. Its inverse is hyperopic vision, where objects at a close distance are blurred. For people over 40, presbyopic vision becomes common, where objects appear blurred at reading distance.
Remedies for Defective Vision
Seeking assistance from an ophthalmologist will usually aid a person to get clear vision. Ophthalmologists will prescribe devices such as eyeglasses and contact lenses to correct defects in vision, but the disadvantage is these solutions are temporary and without these devices the eyes will return to a blurred state. Some people get corrective laser surgery, which is a more long term (and sometimes permanent solution).
Changes in diet in order to accommodate more vision helping vitamins and minerals like Vitamin A can help. Vitamin A is a necessary nutrient in order to help vision remain clear and to avoid further problems, but a balanced diet rich in whole grain, fresh (or dried) fruit, dairy products and vegetables can help greatly as well.
Reduce strain on the eyes and avoid prolonged strenuous activities. There are also exercises which can help. Eye exercises, neck exercises and the palming technique are all beneficial in helping to relax the eyes. Splashing cold water onto the closed eyes also helps it to cool down and boosts the blood flow.
