The eyes are the most important organs of the human body and their importance can be easily derived from the fact that of the eyes of a person stop to function properly, he may lose his ability to see the world around him and may permanently become dependent upon others for his day to day activities. The eyes come in pairs and both of these work in coordination. The eyes function 24 hours a day without any rest and are exposed to all the environmental impurities that can lead to a number of eye problems. Eye problems may also be genetic or hereditary. These may even result from unhealthy lifestyle practices like watching excessive television, spending hours using computer and mobiles and not taking proper care of the eyes. Eye problems can also be triggered by prevailing medical conditions like diabetes, brain tumor etc.

 

One of the most common type of eye problems is low vision. The problem refers to a certain degree of the loss of vision. Complete blindness does not come under this category of visual impairment. The person may have some sight left which is highly distorted and blurred. The problem cannot be treated with the use of normal techniques like using contact lenses and glasses. Eye drops also cannot help to completely treat the problem. Use of magnifying glasses may problem to be helpful but their effect is temporary. The severity of the problem varies from person to person.

Low Vision can be classified into two categories

• Partially sighted: Your vision is between 20/40 and 20/200 with conventional prescription lenses.
• Legally blind: Your vision is no better than 20/200 with conventional prescription lenses. The patients have a restricted field of vision less than 20 degrees wide.

Low Vision can lead to the loss of central vision. The patient tends to develop a blind spot in the center of the field of vision due to which he's not able to perceive the images clearly. Low Vision can also lead to the loss of peripheral vision also known as side vision.  The patient's sight becomes limited below or above a certain level. The central vision however remains unaffected. Night blindness can also be an outcome of low vision. The patient experiences difficulty in seeing objects in dim light especially in places like theaters and during night. The patient may also experience blurred or hazy vision as the objects are either out of focus as a result of which it seems as if the entire field of vision is covered by an opaque film.

Low Vision is very common in people lying in the age group of 45 to 65 years and can be the outcome of an injury to the brain or eyes. It may also be triggered by pertaining medical conditions like glaucoma, diabetes, eye cancer, albinism or even stroke.

If you are experiencing a persistent blurring of vision, immediately consult an ophthalmologist. He may conduct a number of screenings and tests to determine the adversity of the problem and device out the treatment procedure accordingly. Non surgical treatments involve the use of telescopic glasses, light filtering lenses, magnifying glasses, reading prisms and closed circuit video magnification.

Low Vision can be a very depressing experiences and the patient may even require some counseling to cope up with the problem. Surgery can be opted to treat the extreme cases of low vision. It not only helps to correct the problem but also ensures that the problem does not return in future.
