A complete eye check-up would generally comprise of several tests, including:
- Visual Acuity Testing – This is usually done with the help of a standardized chart projected at a distance of 6 meters or 20 feet. The chart has a broken ring, standard size alphabets, or the letters E are used to gauge acuity of vision.
- Color Vision Testing – this test is carried out with the help of Ishihara charts.
- Torch Light test is for checking the movements of eyes individually and together (Pupillary Reflexes).
- Intra Ocular Pressure (IOP) – This test is carried out with a Non-Contact Tonometer (NCT) and when signified with an Applanation Tonometer.
- Slit Lamp test is done by looking at the front lying structures of the eyes.
- Cycloplegic refraction and Dilated Pupil examination for a detailed look at the retina and crystalline lens of the eye.
Regular complete eye check-up is important in many ways, such as:
- An eye examination can reveal early signs of progressive diseases such as Glaucoma and Cataract.
- Objective Recording of change in visual acuity.
- It can detect a change in the power of ‘corrective lenses’.
- Early detection of silent diseases including macular degeneration.
- An eye test can detect the early signs of diabetes.
