1.Color Blindness Test
Which number do you see on the far left? If it’s «3,» you probably have normal color vision. If it’s a «5,» you may be color blind. The center panel shows a mild lack of color vision. Complete color blindness, which is rare, appears at right. No number is visible. Tinted glasses may help you see better.
2.Nearsightedness (Myopia)
Nearsightedness can make it harder to drive, play sports, or see a blackboard or TV. Symptoms include blurred vision, squinting, and fatigue. To correct it, you can wear glasses, contacts, or get surgery in some cases.
