Color Blindness Test : Check your Color Vision Online

8% men and 0.5% women around the world are color blind, yet most of them don't even know about it unless they face some issue related to it. SOme people think that color blindness is having a grey-scale vision, which is not true. Color blind people are not able to distinguish between certain colors and thus it is actually color vision deficiency. Here betterhealthfacts.com has designed a test for you to check if there is some issue with the color vision of your eyes.

Before you go for the test you must know that 4.5 percent of population around the world is color blind. 99% percent of them are red-green color blind. Cone cells in our eyes are responsible for color vision and they are of three types to distinguish the three primary colors: red, green and blue. All colors are made by combination of these colors and thus evaluated by these perfectly balanced cone cells. But if certain type of cone cells are missing or have got their peaks shifted then it causes color-blindness. Even if one type of cone cells are missing then whole color spectrum is affected. Usually color blindness occur due to genetic reasons.

We have designed a test for you to check if you are color blind or not. Just fill in the numbers that can see in the images. Even if you are not sure then you may try your approximate idea or may leave it blank.

Online Vision Test : Check your Eyes using Smartphone / Laptop


Our eyes are one of the most important external organs in human body. A normal person can't even imagine a life without eyes. Yet most of us don't care much about them and never go for a vision test, unless they face some severe headache or focus related issue. We would suggest you to go for a vision test at least once in every 2 years if your are above 40. Prior to to the age of 40, once in every 4 years is sufficient if you are not facing any issue with your vision. In the mean while you can test your sight using the following test to check your vision at home.

How to use the online vision test

Step 1 : Keep your smartphone / laptop at a distance of 1 meter from your eyes.
Step 2 : Keep your left eye closed by placing the hand over it (don't press it) and try to read the alphabets. If you face any issue in reading the letter between green and red bar, then it means that you have got some focus related issue with your right eye.
Step 3 : Keep your right eye closed by placing the hand over it (don't press it) and try to read the alphabets. If you face any issue in reading the letter between green and red bar, then it means that you have got some focus related issue with your left eye.

Note : At any point if you want to check if you read it right, then bring the screen closer and then back to its previous position. Don't try to fool yourself while doing so, as here you are not appearing in any exam, but checking your own eyesight.

Result: If you are able to read all lines perfectly then you have got a perfect eye sight, which is better than 20/20 or 6/6. If you are unable to read last 3 lines then still your eye sight is good and can be made better by performing some yoga exercises for eyes. But if you are unable to read the letters between green and red bar then you must see an eye specialist and get your eyes tested by a professional.
