Importance of regular eye check-up
Regular eye check-ups are not only about making sure your vision is proper, but many chronic health conditions can also be detected through eye tests. As per the experts, we should get our eyes tested at least once in every two years.
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.
- Eye tests can pick up signs of cardiovascular diseases, such as high blood pressure and high cholesterol.
- Your optometrist can detect high blood pressure by examining the blood vessels in the back of your eye.
