• Which one is better in UV protection, Photochromic lenses or Polarized lens?

  Both of them can give 100% UV protection. If you drive a lot, I would suggest you to get polarized lens. They can reduce reflective glare which photochromic does NOT. The photochromic lenses will start to fade in 2 years.

• How to protect my eyes when swimming?

  You should choose the swimming pool with clean water and less pollution. Use some antibiotic eye drops before and after swimming. It is better to get a pair of swimming goggles to protect your eyes.

• Can I upgrade a 1.5 index lens to 1.7 index lens without replacing the lenses?

  That's impossible. The only thing you can do is to replace the lenses if you want to upgrade a 1.5 Index Lens To 1.7 Index Lens.

• Can I wear Multi-focal lenses for presbyopia?

  Of course you can. Multi-focal lenses can offer good vision ranging from near to distant objects. So they can also help people with presbyopia see clearly.

• Can I make the tinted lenses lighter without replacing the lens?

  If the gradient color is in a coating, not in the lens, you may probably change the color. Try to take them to the optical store and ask. Maybe there are some chemical material that can remove it and make the lens retinted.

• What lens index should I get for my prescription glasses?

  Your prescription is strong, so I think 1.67 index will make your lens much thinner and give you a better look. However, you should consult your doctor to determine which one will suit you best.

• What is the problem if I have acute pain in my eyes?

  If there is acute pain accompanied by swollen and blootshot eyes, it could possibly be conjunctivitis. It is highly recommended for you to see the eye doctor. Your vision may get worse rapidly if they don't get timely treatment.

• Can wearing contacts when playing computer cause dry eyes?

  Yes, wearing contacts too long can cause dry eyes easily, and it will aggravate the problem if you wear them for computer use, as you often forget to blink your eyes when staring at the computer screen. So it is not suggested to wear contacts when playing computer.
