| The main role of a lens is to correct the vision of people with myopia, astigmatism, hyperopia and presbyopia. |
| When hyperopia or long sight is the pre-existing refractive condition the ability to focus near object is also lost at 40 years of age. |
| In cases of mild hyperopia, the subject sees correctly in far vision by compensating the hyperopia through accommodation. |
| Whether myopia, hyperopia or astigmatism is present, surgical correction attempts to redirect light rays to accommodate the refractive error. |
| Farsightedness, or hyperopia, is a common refraction problem causing blurred vision of close objects. |
| In cases of severe hyperopia, the eye can no longer compensate in this way. |
