• What to change if I want reading glasses?

  If your prescription is within the expiration time, you can use your old prescription, but make sure ADD number is on your prescription which is specially needed for reading glasses.If not, you should go and to have your eyes examined again to get a new prescription and tell your doctor this pair is for reading glasses.

• Would it be possible that I use my eyeglass Rx for my Contact Rx?

  Your glasses prescription may not be the same as your contact lens rx. Getting contacts is not just about getting the right prescription, it is important to get an eye exam as well in order to make sure that it fits. If a lens is not fitting properly on the eye it may cause discomfort and damage to the eye. Although it is a pain and cost some money, it is important to make sure you get fitted with in an examination.

• Are there any lenses less thick and don't make my eyes look small?

  There are a several grades of "thin" lens that look like normal lenses. You can choose the high index lenses that can make your lens much thinner ,but usually they are more expensive, but worth it. Any optical shop will have them. Just ask!

• What's the difference between sport sunglasses and regular sunglasses?

  I think the most important difference is sport sunglasses can stay on your head firmly when you are doing physical activity such as running,playing basketball etc while regular sunglasses may fall off. Also the sports sunglasses have a better resistance to external hit to protect your eyes.

• What's the highest RX for nearsighted people?

  This varies from different places. The highest rx I've seen was about -15, but I'm sure there are higher numbers out there.You can go to your eye doctor to have your exact prescription and ask them if they offer glasses special for your prescription.

• Can eye doctor convert eyeglasses RX into Contacts RX?

  The power of contacts can be calculated from that of glasses.Here is a formula :Fo=Fs/(1-dFs).The Fo means your power of your contacts and Fs means the power of glasses.dFs means the distance between rear vertex of glasses and your cornea.Usually the dFs should be measured by meter and it is 0.012m for easterners.For example,the RX of glasses is -4.00,the dFs is 0.012m,we can know that your RX for contacts should be -3.82,but this result is not a regular RX,so we choose the proximal and a lower number , it should be -3.75 . Hope these can help. But even if you can make out the RX,you still need an eye exam for contacts.

• Contacts can see better than glasses that are the same prescription?

  Yes,it is normal.Because the strength you need is usually weaker than the glasses.If they are the same prescription,contacts give you higher prescription to see.So you can see better.

• can sunglasses be semi-rimless?

  Of course they can . It is not hard to find that the majority of sunglass models are full frame ones, because sun glasses are basically expected to cover the whole part of the eyes.But semi rimless sunglasses make it a reality to show more facial natural beauty while ensuring enough UV protection.
