Question 8

does mastrubatoin affect on eye vision?

Accepted Answer

No: I'm sorry, I can't read your question. No, masturbation has no effect on your vision. Just make sure your activity doesn't impact your relationship w/your family, friends &amp; schoolmates, nor your school performance. If you were gainfully employed, I'd include work &amp; coworkers in that list. And if you were in a relationship, I'd include partner, too.

Question 9

what can i do to strengthen eye vision?

Accepted Answer

Maintain good health: The eyes respond to good exercise and nutrition like the rest of the body.  Regular exams with an ophthalmologist ( the real eye doctors) can be helpful.  Exercises designed to change the power of the eyes are not helpful.  Getting attention for any major changes should always be done.

Question 10

how are eye vision test generally scored?

Accepted Answer

Compared to standard: The chart used to test the eye is calibrated for normal vision at 20 feet. The outcome achieved is compared to what a normal eye can see at 20 feet. So if you can only see at 20 feet what a normal eye sees at 40 feet, your vision is considered to be 20/40. This is measured with and without corrective lenses at distance and at near. The vision with correction is considered to show the true vision.
