• Is there a difference in reading glasses versus computer glasses?

  Yes.They are different.They are used for different distance, so you'd better not use the reading glasses for computer.Otherwise you will get headache and it may damage your vision.

• How do I keep my basketball goggles from fogging up?

  Spit or lick into your goggles.This can temporarily solve your problem and it is widely used for many people.

• How do polarized sunglasses work?

  It is really a difficult question.I only know that polarized sunglasses can eliminate most of the reflected light from water surface,ground etc.,so they can give you a better view than the ordinary ones.

• How to Get Used to Bifocal Glasses

  Wear new bifocals full-time to make yourself get used to new pair. Retrain yourself how to hold your head for close-up viewing. Change the head angle when eading books. Don't view things far away out of the bottom portion of the bifocals.

• how do I prevent my swimming goggles from fogging up?

  Use an anti-fog spray or put anti-fog coatings on the lenses of your swim goggles.

• what are non prescription glasses

  Non prescription glasses means you have perfect eyesight and have no need to correct your vision, that is, you don't have to need corrective lenses.So people wear non prscription glasses only for fashion purpose other than correct vision defects.

• How to choose swimming goggles?

  You should check whether the lenses are comfortable and the nose bridge will hurt you.Then put the straps on to see whether the straps are too tight or too loose.If all of them are comfortable, you can get them then.

• Can you wear ski goggles without a helmet?

  Of course you can.Some people will wear ski goggles not with a helmet but with a fashionable hat. But I should say a helmet is much safer than a hat. If you just go skiing, you'd better wear ski goggles with a helmet.
