Hyperopia means long sighted
People who are long sighted maybe able to see well at distance but often can't see well close up. Those with mild hyperopia maybe able to manage without vision correction, whilst those with higher prescriptions or who are older, may find it difficult to focus at any distance.
An eye that sees well without spectacles is the right length and therefore light falls onto the retina where the image is processed by the brain to form a clear picture.
A long sighted eye is usually too small or the cornea is too flat. If the lens cannot compensate (presbyopia) the image focusses behind the retina, rather than on the retina, causing a blurred image.
A plus correction is needed to correct the problem. If you have a +2.00D lens prescription for example, then you are long or far sighted.
Permanent solutions to the problem are also available, including LASIK and LASEK. Excellent results can also be obtained with Refractive Lens Exchange (also known as PreLex and Clear Lens ExChange, to name but two).
