• Is it possible to get non-prescription contacts to change your eye color?

  Of course you can.I have seen many girls wear such colored contacts for beauty.It should be safe but you can't wear it for too long,usually no more than 8 hours a day.If you feel any discomfort,stop wearing them immediately.

• Are eye drops really safe for our eyes?

  Of course they are safe.They are just artificial tears.But you can't use them too often,otherwise the producing of tears will be affected.

• Can I wear glasses that are too weak for my eye sight?

  I have heard that it is better to wear glasses a little lower than your prescription degree,but too weak for your eye sight obviously will not do good to your eyes.

• Can I wear my glasses upside-down?

  I think the 0.25 difference will not matter much.But if you feel any discomfort,go to visit your doctor.

• How to convert my glasses prescription into a "20/20" type measure?

  There is no rule to convert the prescription to "20/20" type measure,You can get an approximation if you are shortsighted. 20/20 plano 20/30 -0.50 20/40 -0.75 20/60 -1.00 20/80 -1.75 20/200 -2.50.So you may be 20/80.

• Is it possible for eye prescription strength get better?

  If you are meaning vision gets better by "prescription strength get better",I think the answer is no.The best condition for your eyes is they stabilize at a certain level and don't get worse anymore.They can't get better naturally.

• How can I know if I need a new prescription for glasses?

  If you can't see as clearly as before with your current glasses and you always find things blurry, then it is a sign that you need a new pair of glasses. So you should go to see your doctor and have an eye exam.

• Which lenses are good for night driving?

  For night driving, a pair of glasses with clear lenses and anti-reflective coatings is a good choice. This kind of glasses will reduce the internal reflection within the lenses and halo problems so that it will give a better vision to the wearers. And there is no need to tint your glasses.
