What are the benefits of eye tests?

According to the World Health Organisation, more than 80% of blindness is preventable, and people can easily avoid such problems through regular eye check-ups. If you ignore such eye tests, then you can miss the chance of full recovery, and you cannot protect your vision. You need to provide your eye-test reports to your employers, and you cannot join the army, defense, and scientific industry without getting your eyes tested. Accurate vision is necessary for certain fields, and you need to be prepared for the same.

Different types of eye tests:

• Visual acuity test: In this, the optometrist will conduct this eye test in his or her chamber, and you need to read the letters from a sign. The sign is positioned a specific distance away, and an optometrist will check your vision by using some glasses.
  
  
  
  
  
• Radioscopy: A machine called a phoropter is used in this test, and it helps your optometrist with an optical lens prescription. An optometrist will change the lenses in front of your eyes, and he or she will also focus light into your eyes. So, it will determine the reflective vision of your eyes.
• Refraction test: An optometrist can prescribe eyeglasses after this test. He or she will look into the phoropter and ask you to check the eye chart positioned on the opposite wall. Your optometrist can use a series of the lens for this test, and he or she will prescribe your eyeglasses based on your answer. These eye test will help your optometrist determine whether your eyes are nearsighted, farsighted, or affected by astigmatism.
• Keratometry test: This eye test can measure the shape and curve of your cornea. If you have an elongated shaped cornea, then you can suffer from astigmatism and you must go for this test to check your eyes. The doctor will use a machine for this test, and he or she will adjust the machine to check the cornea's shape.

Proper examination of the eyes can also help in the early detection of stages of glaucoma or cataracts. If you can find these problems at an early stage, there is a better probability of getting them cured, and preventing loss of vision.
