• Do polycarbonate glasses get scratched easily?

  Yes, it is true. Polycarbonate can get scratched even you are cleaning them. Some people scratch their lenses by cleaning them with paper towel. So you should be much careful with the polycarbonate lens and it is better to add an anti-scratch coating on it.

• What are the advantages of progressive glasses over lined bifocals ?

  Traditional bifocals and trifocals may bring “image jump” since they have sharply defined boundaries between different parts of the lenses. In contrast, progressive lenses offer a smooth and seamless power transition, so that images at varying distances are also smooth and comfortable.

• Can I wear gradient sunglasses for driving?

  Yes, you can use it for driving because the clear part on the bottom won't dim your view of the dashboard. But they are not effective in reducing glare when driving at night.

• Why do I have eye strain when using computer?

  When you do too much work on computer, it will make your eyes tired. What's more, when you concentrate on the computer, you often blink less, which will make your eyes easy to dry out. So you often get eye strain when using computer.

• My eyes are still red and sore after a few weeks after cataract operation?

  As the surgery is successful, I think it should not be surgery complication. It may be caused by conjunctivitis or a dry eye. You can try to use antibiotic eye drops first. Otherwise you need to see the doctor.

• How to choose frames that fit my face?

  To choose a good frame that fit your face, the try on process is very important. You should make sure that the nose pads fit snugly against the nose so that the glasses don’t slip, and that the temples fit the ear closely.

• Can I change regular lenses to photochromic after they are made?

  No,you can't. The photochromic lens is not simply a coating on it, but has special chemical material in the lens. So there is no way to change the regular lenses to photochromic. You need to buy a new pair.

• Is there a device on the market that can help to insert and take out contact lenses automatically?

  I guess there is no such device that can help you insert and take out the contact lenses automatically. But it is quite a good idea. If such device exists, it must be very popular. You can buy extended contacts which don't need to get in and take out frequently.
