• When should I wear glasses for nearsightedness?


    If I use glasses for nearsightedness, should I wear them all the time or only for distance vision? Can I use them for reading?


    You will quickly discover when your glasses help you. You do no harm by taking them on or off. If you are younger than 40, nearsighted (myopic) glasses will provide clarity for you at distance and will help especially for night driving. If your prescription isn’t too strong, you can probably take them off to read or do other near work. If you are much over 40, you likely have developed presbyopia (age-related loss of close vision). But in this case you probably have bifocals or reading glasses for near vision.
