Farsightedness (Hyperopia or Hypermetropia) is a refractive eye defect in which distant objects can be seen clearly, but close ones do not come into proper focus. It is caused by a lack of elasticity of the eye lens, meaning the lens is not capable of flattening, or if the eyeball is too short. Farsightedness can cause eye strain or eye and headaches.
Hyperopia correction requires lenses with PLUS dioptric value.
The result of farsightedness is that light beams focus behind the retina, so the eye can’t properly focus the light that enters. Common eye tests, such as those performed in schools, may not immediately detect hyperopia. If you have difficulty focusing on close objects, it is necessary to visit an optometrist for a thorough exam and diagnosis.
Hyperopia is the result of the visual image being focused behind the retina and can either be a hereditary condition or caused by difficult surroundings that cause prolonged eye strain.
Hyperopia can be treated with glasses or contact lenses by changing the way your eye bends light rays. Many people can wear contact lenses that are much more comfortable to treat farsightedness. Others prefer to buy reading glasses for occasional use.
In the picture above, you can see an illustration of how hyperopia affects your vision. Light rays entering the eye are focused behind the retina, causing images to appear blurry. You can see how someone with hyperopia sees the world compared with someone with normal vision.
