Understanding Farsightedness

Farsightedness or hyperopia is a visual defect where a person can see objects clearly from afar but have trouble seeing object from up close. This vision defect is caused by an imperfection in the shape of the eyeball where it becomes too short or when the lens can’t become round enough.

This defect causes the inability to focus on nearby objects. As the object comes closer, the eye must try to increase its power in order to focus the image of the object on the retina. Once the power of the cornea and the lens cannot compensate enough, the image appears blurred.

Causes of farsightedness

Farsightedness happen when the eye is too short and not enabling light that passes through it to bend correctly. This causes the image to focus somewhere behind the retina instead of on it, causing the object image to appear blurry. Farsightedness usually occurs in early childhood but that which can be corrected during normal growth and development.

There are times that a child may still experience far sightedness after the eye has stopped growing, usually when the child is around 9 years of age. At this time, the eye may still be able to adjust and correct the problem. But with age, the capacity of the eyes to adjust and focus diminishes and so farsightedness becomes more obvious.

Symptoms of farsightedness?

There are many symptoms that accompany farsightedness. One of the most common includes blurred vision especially during nighttime and trouble in seeing objects up close. This symptom of farsightedness can sometimes be confused with presbyopia which is another eye condition that can cause blurry near vision due to the diminishing ability of the eye lens to focus with age. Other symptoms accompanying farsightedness include eyestrain, aching eyes as well as the occasional headache.

How to treat farsightedness?

Most cases of farsightedness usually do not require any treatment especially during a person’s younger years. The problem can usually be corrected naturally by the adjustment capabilities of the eyes. But as a person ages, the capability of the eyes to focus diminishes where the problem then becomes more prominent.

During this time, a person may now require the use of eyeglasses or contact lens to remedy the problem. Surgery is an option available for people with severe farsightedness which might require eye lens replacement.
