Here’s a complete guide to some eye tests that should be conducted frequently to keep a check on the eyesight.

In this test, you are asked to read an eye chart in which the words are scribbled in various fonts & sizes. The result gives a fair idea about the distance visual acuity and hand-held acuity to measure your near vision.

- Cover Test:The cover test is very useful to detect strabismus, binocular vision, amblyopia, eye strain etc. It is one of the basic tests wherein the doctor will ask you to focus on an object placed nearby and cover each of your eyes alternately. The procedure is repeated while you try to concentrate on an object placed at a distance.
- Ocular Motility:The test is used to determine the movement of the eyes in terms of speed and accuracy. This also includes testing of smooth eye movement wherein the ophthalmologist may ask you to follow the movement of a light or some other source. To check the quickness, you may be asked to move your eyes between two different objects placed at a small distance. Issues related to eye movement can cause strain on the eye, readability, sports vision etc.
- Stereopsis Test:It is a depth perception test and is also conducted to detect appreciation of the 3D objects. The test is generally conducted to detect ocular motility and strabismus. There are almost six different types of stereopsis.

The doctor will then put eye drops containing fluorescein that wash away tears and make the pupil dilate. A slit lamp having high-intensity light is used to examine the eye. Eye problems like Macular degeneration, Retinal detachment, Cataract, Cornea problem etc. can be easily detected.
