Defective Vision

Defective VisionWhat is Defective Vision?

By the name itself, one could infer that defective vision is having a vision which could be regarded as falling below the normal range of eyesight. The acceptable and normal visual acuity is rated at 20/20. If you recently had your eye checked and you do not have this standard vision, then you have a defective vision. You could always opt for eyeglasses as most doctors would suggest, however, long-term use of eyeglasses do not actually abate the problem but tend to worsen it since the eyes are made to focus through the lens’ centre. Those wearing eyeglasses would need to move their heads towards the direction that they are trying to look at instead of only moving the eyes. The effect of all these is that some of the muscles of the eyes are not used, causing them to degenerate slowly. So wearing eyeglasses is not automatically the only solution whenever one is suffering from defective vision.


What Causes Defective Vision?

Defective vision can be attributed to different causes. Some of which are the following:

  • Wrong nutrition. The eye is one of the parts of the body that require adequate nutrition. When the body accumulates toxins, the eye becomes affected too. Usually, this condition is brought about by too much sugar, starch and protein. The blood vessels that surround the eye usually clog up when there are already too much toxins in the body, which then hampers the eyes’ normal function.
  • Lack of vitamins in the daily diet. Vitamins A and E are some of the vitamins that the eye needs for proper functioning. Being deficient in these vitamins could usher in some eye problems.
  • Straining the eyes. This can be brought about by overworking the eyes. Reading in either dim or glaring light can cause much strain on the eyes. Reading in moving vehicles could likewise strain the eyes.
  • Improper blood supply. When blood does not flow well to the eyes, different parts of the eye would not be able to function properly.


Diagnosis, Signs and Symptoms of Defective Vision

Usually, problems with vision would not just happen overnight, except in rare cases where the stimulus would be overwhelming, like those that happen in accidents. Defective vision would often develop gradually. Some of the common signs and symptoms of defective vision are:

  • Being farsighted. Some people would see things close to him as a blur but would see far objects clearer.
  • Being nearsighted. There are people who would see things that are near him clearly but would see things that are far as a blur.
  • Finding it hard to focus. Some people would get watery eyes whenever they try to focus their vision on a particular object.
  • There are people who are actually color blind and would find it hard to distinguish colors.


Remedies, Treatment and Cure for Defective Vision

Usually, you could remedy a defective vision through proper nutrition and some exercises. The right diet would provide the eyes with the right nutrients and exercises would be able to relieve the eyes from strains.


Exercises for Defective Vision

  • Eye exercises are among the most effective remedies for defective vision. This will allow the muscles to loosen up. You can move your eyes slowly up and down, left to right and back. You can do these exercises for 2-3 times. You could even do this 6 times. Another exercise you can do is to practice focusing. You can try to hold a finger in front of you, roughly 8 inches away, then try to shift your focus from your finger to a much larger object situated around 10 feet or more away.
  • Neck and shoulder exercises. You can try moving the neck and shoulders in circles and in semi-circles. You could also move them clockwise and counter-clockwise.
  • Splash some plain and cold water onto closed eyes, then try to rub the eyelids. Make sure that the eyes are closed when you do this.
  • You could also try covering your eyes with your palms as you sit on an armchair, and imagine that everything starts to get blacker and blacker by the minute. This helps in reducing the strain that the eyes suffer and helps in relaxing eyes and the tissues.
