• Why can I see better with plastic frames?

  Some high myopes find that they can see better with plastic frames rather than metal ones with nose pads. The distance between the back surface of the lenses and the front of the eyes is named vertex distance, which can be increased by equipping nose pads in metal frames. Plastic frames with a shorter vertex distance are more suitable for highly myopic people. More specifically, some metal frames have unadjusted nose pads, creating a greater vertex distance and making the wearer see a poor-fitting bridge easily. Plastic frames do not involve any nose-pad adjustment and the bridge will always stay at a right place.

• Why eyesight disorders can be corrected by wearing glasses?

  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. Eyeglass lenses are curved pieces of glass. The curvature of the lens bends the light rays as they approach your eye. This helps the rays focus on your retina, instead of behind or in front of it.
