Custom reading glasses can help you see better than the ones you buy at the drugstore.

close-up of brown eye

Custom reading glasses can help you see better than the ones you buy at the drugstore.

  • Your Answer: 
  • Correct Answer: 

Explanation: Vision typically differs from one eye to the other, and prescription glasses can meet each eye’s needs. Also, custom lenses are crafted to account for the specific distance between your eyes. Still, store-bought glasses are cheap enough that you can have several pairs, and they're not likely to hurt anything -- unless by using them, you are missing regular eye exams.

It might be OK to sleep in ...

  • Your Answer: 
  • Correct Answer: 

Explanation: Extended-wear contacts are designed to be worn for several days and nights, usually no longer than a week for many lenses, without cleaning and disinfection or replacement. However, doctors often don't recommend sleeping in contacts as it raises the risk of infection. Check with your eye-care specialist at the first sign of anything different -- pain, discharge, or a change in vision.

close-up of brown eye

You should always get UV-protective coating on your lenses.

  • Your Answer: 
  • Correct Answer: 

Explanation: Shatter-resistant polycarbonate lenses, commonly used in sports, usually come with full ultraviolet protection. So do high-index lenses, a type of lightweight lens that allows people with strong prescriptions to avoid having very thick lenses. But UV coating is a good idea for people ordering less expensive lenses made of a plastic called CR-39.

close-up of brown eye

How can astigmatism be corrected?

Circle lenses are cosmetic contact lenses that ...

  • Your Answer: 
  • Correct Answer: 

Explanation: You should seriously weigh the benefits and risks of wearing contact lenses for a purely cosmetic purpose. If you are considering cosmetic contact lenses, it's a good idea to discuss with your eye doctor and have the periodic exams that are required for all contact lens wearers. Decorative lenses purchased at places like costume shops are illegal and could cause eye damage.

Children too young to read an eye chart can't get glasses.

  • Your Answer: 
  • Correct Answer:

  • Your Answer: 
  • Correct Answer: 

Explanation: Saliva and tap water are unsafe.

In general, if you wear soft contacts, carefully store the lens in saline or soaking solution as soon as possible until you can clean it. (If the lens is damaged or irritating, don't use it.) If you wear disposables, replace the lens with a new one. If you use gas permeable lenses, store the lens dry until you can care for it.
