• Is it bad to use eye drops every morning?

  Most the eye drops not only have the function to treat some eye problems, but also they contain some anticorrosive ingredient. If you use them frequently, the anticorrosive ingredient will damage the structure of ocular surface and cause irritation. So you can use a small amount of eye drops when your eyes get tired to relieve the eye fatigue. Eye drops can not be prolonged use.

• Can I get the Anti-scratch coating after my glasses are cut?

  Some optical stores are unwilling to add the anti-scratch coating to your lenses if it has already been cut. While there are still opticians that are willing to do it for you. But it may be costly. If you do want to add the anti-scratch coating to your glasses lens, you can shop around to see which store can help you.

• Is it possible to add anti-scratch coating to my lenses?

  Yes. You can take your glasses back to the place where you bought your glasses and ask them to add anti-scratch coating to your lenses. They will send your glasses to their lab and the technician will do it for you. It may take you some time to get your glasses back.

• Can I use eye drops when I am pregnant?

  If the eye drops are only used for re-wetting and lubricating,it is safe to use.But you should be careful with antihistamine eye drops for allergies.

• Are anti scratch lens supposed to be thicker than regular lens?

  If the left lens is much thicker than the right,I think there may be something wrong in "refractive index" or "material" for the lens.You can go back to the store and have a check.

• Is there any eye drop that can brighten the white part of my eye?

  You can use the eye drop which contain vascular constrictor to make your eye whites brighter. The vascular constrictor will make the white part of your eye white by constricting all of the blood vessels in your eyes. You can get these eye drops from most pharmacies. But I think you should talk to your optometrist first because it may cause very little side effect with prolonged use.

• Does the optometrist keep my prescription?

  Make sure your prescription is still valid. Every optician will keep the customer's information on file. So you can retrieve your prescription from your optometrist as long as you go back there and show him the reciept in order to let him know that you've done an eye exam before there. Then he will write down the prescription to you.

• How do I know my glasses have anti-glare coating?

  You can hold the glasses where they will reflect light. If the lights reflecting are the color of the lights, you do not have Anti-Reflective coating. If they reflect in a color like green, gold, purple or blue, you have the coating.
