if a person has only short sight, then is it recommended to wear spectacles while reading book also?

Question

Or should he/she remove it when not required (eg: reading book)

Answer 1

That's going to vary with the individual.

Many will not need glasses for reading, but some will be better-off using them even if the focus is good for near because the normal effort of focussing (not fatiguing in young people as a rule) can improve the ease with which the two eyes coordinate.

Just occasionally, it's the reverse and it is much better to read without glasses.
There is a marginal long-term effect in that people who have habitually read without their glasses tend to have slightly lower flexibility of focus, "accommodation", in their early forties. But there may be a marginal effect on slowing the rate of short-sight development, too. Neither is a deciding factor on behaviour, if people do or do not prefer reading without glasses.

Answer 2

I am a near sighted person, normally I do not wear spectacles when reading a book but my friend on the otherhand is far sighted so she reads books with spectacles or reading glasses. Hope this answers your question.

Answer 3

If you wear glasses, your doctor should have told you what to do with them. In theory, the glasses should be worn at all times since the prescription should have been made to accommodate your particular problems. As the doctor who gave you the glasses you are wearing. IF they aren't prescription glasses and you can see fine when you read without them, don't wear them. Hope this helps!!!
