Testing the eye sight and determining weakness in vision is an easy task.

By following the instructions given below, one can easily test his sight at home without the need of an eye doctor.

• Place the facing chart (called 'E Chart' at a distance of 3 meters/9.6 feet)
• Cover your left eye with one hand and try to determine which direction the character 'E' is facing, use your right eye.
• When finished with right eye, repeat the exercise with left eye.
• This can also be exercised to determine wether the glasses someone is currently using are still good for him.
• Smaller the symbols you can determine, better is your eye sight. The figures below each line of symbols tell how good or weak the eyesight is.
• Normal eyesight falls between 6/6 and 6/18. Higher numbers represent weaker eyesight.
• 6/6 - 6/9 is normal vision; no glasses needed.
• 6/12 - 6/18 will need glasses for driving and at school.
• For 6/24 - 6/60, patient must use glasses.
• When eyesight is found weak, try checking vision through a pinhole. Pinhole phenomenon can be developed pinning a small pin-sized hole in a hard paper and covering eye with that paper, positioning the pinhole so the subject can see through that small hole.
• If vision improves with pinhole, you can get glasses from a optician. Otherwise, you must see an ophthalmologist.
• This is good for checking only distant eye sight.
