Farsightedness (also known as hyperopia) affects almost 25% of U.S population.
Common signs of farsighted people include squinting, eyestrain, headaches, and difficulty in concentrating when they do close up work (such as working on computer and reading, ).
If you have hyperopia, this article aims to help you understand the condition and find ways to correct it.
It is a common vision disorder in which one can see distant objects well but having difficulty in focusing on close-by objects.
A metaphor will be a severely farsighted hunter who can hit flying duck but he can’t see clearly whom he is kissing.
It happens when the eyeball is either too short from back to front or the cornea is too flat.
When light passes through the eyeball, it lands at a point behind the retina rather than on it.
Thus causing the blurred vision.
When we look at distant objects, the rectus muscles will contract and squeezes the eyeball, making it shorter so that the light lands on the retina (click to learn more about eye muscles).
However, if nothing is done to relax these muscles over a prolonged period, the eyeball conforms to its shorten state.
The distortion in image can also happens when the ciliary muscles are too weak to contract enough upon lens, making it too flat to refract the light onto the retina.
Hyperopia is often mistaken with presbyopia (aging vision).
Even though both have similar symptoms such as close-up objects appearing blur, they are two different conditions.
Presbyopia is age-related, it is common among people who are 40 years old and above.
As one gets older, the crystalline lens harden and becomes less flexible.
If a farsighted person starts having presbyopia, they will experience more difficulties in seeing near objects.
Many children are born with hyperopia but as children have very flexible crystalline lens, it helps them to overcome the problem.
Eventually, some of them will outgrow it as the eyeball lengthens when they grow older.
However, it is important to take note this as hyperopia in children is often gone unnoticed.
The common visual tests in school are generally ineffective in detecting this vision disorder.
As hyperopia can affect learning ability, I think it is important to bring your child for a comprehensive eye test if you suspect they have the condition.
It is important to correct this vision disorder. Especially for children, as if it is left untreated, hyperopia can result in the following complications:
these are some ways which you can correct the problem. In each, I am
going to share with you the pros and cons of each approach.
