All types of Spectacles and Contact Lenses are available at our centre. Spectacles and contact lenses are used to correct the refractive errors which are of following types.

1. Myopia : The light rays in this disease get focused in front of retina because of excessively long eye ball. This error is corrected by giving minus lenses in front of eye.

3. Astigmatism : Here the light rays in one meridian fail to focus on retina . this is corrected by giving cylindrical glasses which have axis reading. All the above 3 types of errors are corrected either by spectacles or by contact lenses.

Contact lenses : These have definite advantage over the spectacles. visual field is large and natural with contact lenses as compared to spectacles. Patient can get rid of glasses, play, swim or can do any activity by wearing contact lenses . These lenses have to be put on in the morning and removed before going to sleep. The patient is given training for that. These lenses are put on outer surface of eye (over black part) and are not to be confused with intraocular lenses which are permanently placed inside the eye after removing cataract.
