The result is, he has colour vision deficiency. CVD is usually an inherited condition. A person with CVD has difficulty in telling certain colours apart. This is due to a defect in the colout-sensitive cells of the eye. Samuel's is red-green deficiency, which mean, at time he is not able to differentiate the colour of red and green.
Not a serious one. He can differentiate green and red seperately, but he got some answers wrong when told to read the number from colourful dots.
I belive most of you has done this test before when you are young. The test looks like this :
Was told by the doctor this was caused by gene. I might be the carrier as my bro also has this problem. CVD can't be cure. The doctor has issue him a certification letter. This letter can be use for "O" level physic exam or army or when he apply for job etc.
Hope this will not affect his future career or life style.
