Question:

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

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


Answers:

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.
