• How does eyeglasses correct vision problem?

  Eye glasses work in the same manner whether they are for nearsightedness or farsightedness. The eye glass lens is curved so that it bends the light rays that hit your eyes so you can see images clearly. Nearsighted individuals cannot clearly see things that are distant. This happens because the light rays come into focus in front of the retina. Farsighted individuals have the opposite problem. The shape of their eyes causes the light rays to come into focus behind the retina, causing things that are near to them to be out of focus. Some people have blurry vision due to an astigmatism, or a condition where the curvature of the eye is irregular, creating a second focal point within the eye. All three of these common problems can be corrected with glasses. Source:http://www.glassescrafter.com/information/how-glasses-correct-vision.html

• Is there an eyewear to help relieve computer vision syndrome?

  Computer glasses are special glasses prescribed to lessen the symptoms associated with computer vision syndrome (CVS). CVS describes a group of symptoms caused by prolonged computer use. Symptoms appear because the eyes and brain react differently to words on a computer screen than they do to printed text. Symptoms often include eyestrain, dry eyes, headaches and blurred vision. Many people try to compensate for these vision problems by leaning forward or by looking down to see through the bottom portion of their glasses, often resulting in back and shoulder pain.

• Is there any kind of lenses that can block glare at night?

  Some people wear sunglasses or polarized glasses to reduce glare when they drive at night. I am not sure whether they do work well. In my opinion, the best choice for night driving is to get a pair of eyeglasses with clear lenses and add an AR coating to the lenses, which will help block glare while driving at night.

• Do the eyeglasses online only come with frames????

  As I know that most of online optical stores sell glasses not only with frames but also with the whole pair( frames and lenses in) ,so you don't need to take it to your opticians to put lenses in. You can have your eyes tested and get a prescription from your eye doctor, enter your prescripion online at the store you prefer, then they can start to process the eyeglasses prescribed with your prescription.

• What kind of sunglasses are good for me?

  Dark tinted color lenses can protect you from brightness, such as brown/gray/green.Polarized lenses could also prevent you from glare. If you often work outdoors, you'd better choose these kinds of lenses.

• How can I repair the broken arm in glasses?

  In most cases, the broken arm may be caused by the missing of screws. A replacement screw will fix the problem. You may go to the local optical store and ask the workers to fix the right screw for your frames. If the screw on your frames become loose, you can use a screw driver to tighten it. If the arms of your frame is broken off, you may repair broken frames at the temples by using hot glue (for plastic frames) - boiling water and pins. Alternatively, replace the temple piece with a piece from another set of glasses. Unscrew the hinges and screw the new temple piece into position.

• Can I make the sunglass lenses to prescripted ones?

  Yes, you can. You can take them to any local optical stores and ask the workers to change the non-prescription lenses into the prescription lenses prescribed according to your power.

• Can I return the prescription eyeglasses I purchased online?

  That will depend on the condition why you want to return your prescription eyeglasses. What's more, different stores have different rules on return and refund. I am sure most stores will ask you to pay for the shipping cost if you return your glasses that you buy online.
