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.

1. Hidden Numbers Test
What do you see in the picture?
Well, these aren’t the swimming pool tiles.
It’s the number 503!
It’s not blood.
The red colour is the most tricky one.
Do you think you got it?
If you could see the number 643, then you are lucky that you do not have red colourblindness.
Looks the grass in your lawn, right?
But, can you figure out what the number is?
Give another look.
Did you find it?
You are right. It’s the number 276.
Out of the blue!
Come on; it’s just a two digit number!
Could you find the number 84?
If you couldn’t figure out most of the above images, you need to give your eyes a bit of rest. Relax, look at the stars for awhile. Let your eyes be free from artificial lights for some time.
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.
Can you see 7 and 16?
This one must be easy for you if you don’t have any colour deficiency.
You are right. It’s the number 12 and 9
This one is a toughy.
Do you see anything?
Could you find any number?
Well, people with red-green deficiency can see the number 45 in the above picture.
3. Hidden Words Tests
Do you see any letters?
What is the word?
If you find Daltonism, then be glad that you don’t have it. It is another term for colour blindness.
If you are not able to see any word in the above picture, you are colour blind.
On the other hand, if you can find the word ‘Vision’, then your vision is undoubtedly bright.
4. The Butterfly Test
Believe it or not, there are butterflies in the picture.
Can you see them?
Do you know, that red-green colour blindness affects men more than women?
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.
