Far Sighted
Hyperopia
Also known as far sightedness, is the condition in which a person can see distant objects better than closer objects. Light being bent inwards by the lens is insufficiently bent and converges at a point behind the retina. This is illustrated by the image below, note the light rays converge behind the retina. To focus that convergence point on the retina, the lens would need to pull in and thicken up.
Causes
Generally far sightedness occurs when the eye ball is somewhat small, causing the light to focus behind the retina. Or alternatively it could be described as the lens not contracting enough to focus the light correctly.
Treatment
The generally accepted treatment is glasses or lenses. Another option, albeit an unattractive one, is surgery to create mono vision. This is also used for myopia. The method is to make one eye short sighted and the other long.
Eye exercises are considered by many to be of value. We at avoidglasses.com believe a natural solution is the best solution. There are many similarities between presbyopia and hyperopia. After all they are both far sighted. One is attributable to a weakening and stiffening of the lens system, the other is attributable to eye ball size.
For this reason, we support the view that eye exercises which re-train the visual system and brain patterns associated with convergence and accommodation can be highly effective. We do not believe that basic eye exercises will provide significant improvement.
The Eye Gym has exercises specifically for far sighted and reading blur.
