hypermetropia defect of the eye

Hypermetropia - You must have seen middle aged people holding a book away from their eyes to read properly. This is because they are not able to see the nearby objects clearly. We say that those people are suffering from hypermetropia (long sightedness). Hypermetr..

Hypermetropia is caused due to the following reasons: Shortening of the eyeball, that is, the eyeball becomes smaller. Increase in focal length of the eye lens. Focussing of light rays in normal eye and long sighted eye Let us now see how this defect..

Defects of Vision - A normal eye can see all objects over a wide range of distances i.e., from 25 cm to infinity. But due to certain abnormalities the eye is not able see objects over such a wide range of distances and such an eye is said to be defective..

">Refractive Errors or Defects of Vision The abnormalities in the normal vision of the eye due to the change in focal length of the lens or due to the deformation of cornea are known as refractive errors or defects of vision. Myopia Myopia is an eye defe..

The light coming from an object enters the eye through cornea and pupil. The eye lens converges these light rays to form a real, inverted and diminished image on the retina. The light sensitive cells of the retina gets activated with the incidence of light and generate electric ..
