Strabismus And Contact Lenses


Strabismus is a vision disorder in which your eyes are not aligned or your eyes do not look towards the same object together. It is really hard to detect and can be constant or intermittent. It results in affecting one eye or can alternate between the two eyes. Mainly, there are four types of strabismus which are based on the direction of the misaligned eye. These are:

A) Exotropia- In this condition, one eye points out or have a look like wall-eyed.
B) Esotropia- In this condition, one eye points in or looks like cross-eyed.
C) Hypertropia- In this condition, one eye points up.
D) Hypotropia- In this condition, one eye points down.

Unequal pulling of muscles on one side of the eye or a paralysis of the ocular muscles results in strabismus. Normally, when a person with farsightedness tends to focus to compensate, he ends up developing accommodative strabismus. This condition is common in people below two years of age up to six years. In some cases it is also caused by the over action of one or more muscles due to uncorrected farsightedness. Some of the symptoms of strabismus includes:

A) Squinting of one eye because of bright light.
B) Decreased visual acuity in the turned eye.
C) Uncoordinated eye movements.
D) Poor depth perception
E) Double vision
F) Headache and eyestrain

Moderate and severe strabismus is easy to detect by simply observing the person but in some cases the degree of eye turn is so small that it can only be detected with specialized training by your doctor.

After examining, your doctor may order you a particular treatment option for its cure. The first step includes a complete eye examination to determine if corrective lenses are indicated. In case of expected farsightedness, eye drops are added to relax the focusing muscles of the eye. But many children with strabismus are treated by wearing prescribed lenses which fully correct their vision disorder. Other treatments includes surgery and vision therapy. No matter what treatment option is applied for its cure, its really important to detect and treat strabismus as early as possible for the best results.
