Time To Check Whether Your Eyes Are Healthy Or Defective

With all the gadgets around, it is not uncommon to see people glued to their laptops or smartphones screens. Constant exposure to the bright lights from the screens can affect our vision. The typical effects of long-term exposure to the screen-light can cause blurry vision, soreness and dryness in the eye, leaving your eyes drowsy and fatigued at the end of the day.

People across the globe suffer from some ophthalmic problems due to their genetics, an accident or due to old age. Colourblindness, also known as Daltonism, is a condition where a person cannot see the world in colours, but only in the grayscale. Nearsightedness makes people unable to see distant objects clearly, while farsightedness renders one to see only the distant objects. Astigmatism, an old age problem, is a condition where the person’s eyes cannot focus on any object at all.

Most of the times, a person doesn’t know whether they have some defect in their eyes. They are so accustomed to the things, they feel like it’s always been like that, and everybody else must be seeing the same.


That is why Banter picked up some simple eye tests so that you could know whether or not you are suffering from some eye condition.  For the tests, you need to keep your screen at least 75 cm away from your eyes.

2.  Ishihara Tests

These tests were developed most famously by Ishihara Shinobu, Professor of Ophthalmology, the Imperial University of Tokyo (between 1922-1941). The Japanese Pseudoisochromatic tests check a persons ability to see the colours.


What numbers do you see?

If you see only the number 1, then you are suffering from red colourblindness.

If you see only the number 3, then you are suffering from green colourblindness.

The red-green blindness is the most common colour deficiency in the world.

A healthy eye would detect the numbers 13  and  8.

This picture has been in use since 1917. Unbelievable, right?

This test was the first picture that Ishihara developed to check the red-green colour deficiency.

If you could figure out most of the items in the images, then your eyes are healthy. However, we suggest you should give your eyes some rest.

If you were unable to detect the items in the pictures (or if it was tough for you to figure them out), you might be suffering from colour blindness. We recommend you consult an Ophthalmologist.
