If I wear eyeglasses because I have a slight astigmatism, will it worsen my nearsightedness/farsightedness?

Wearing glasses NEVER makes the correction for near- or far-sightedness worse. It should make your entire vision better. The only exception is for those of us over 40, wearing just the correction for our nearsightedness without a bifocal, can make it more difficult to see at near when the glasses are on. Those over 40 usually consider a bifocal/no line spectacle correction for this reason.
