  • Computer glasses and reading glasses have different focusing zone. Computer screens usually are positioned 20 to 26 inches from the user's eyes. This is considered the intermediate zone of vision — closer than driving (""distance"") vision, but farther away than reading (""near"") vision. Reading glasses are prescribed to correct near vision only. They can also be made with the same pair--bifocals with the upper part to see computer and the lower part to see near.

  • The need for glasses varies greatly from one person to another and does not have much to do with the degree, ok? Often a person who has a degree feels much the lack of glasses than one which is 2.5.

  • Surely it will be much better if you take them off the focus on a distant . but I think using them for short-time distant seeing will not affect that much .Actually ,the point of seeing far away every 15 minutes is to give your eye muscles a relax ,if you don't want to take the trouble to take them on and off ,you just need to blink your eyes several time or close your eyes for seconds .

  • I am 23 and don't need reading glasses . But my father started using reading glasses few years ago (about 45). He could not see the small texts on newspaper . It is also impossible for him to thread a needle. And often get frequent headaches, eyestrain or eye fatigue while reading. I don't have shopping experience from 99 cent store and unable to know the quality of their glasses . Generally glasses can still work without any big problems unless your prescription change .

  • why not go to visit both of them and have a look by yourself ? If you have ideal designer glasses ,just take a comparison between them and you will find which is cheaper . But generally ,Lenscrafters have a wider selection for designer glasses.

  • Apart from the drug store or a dollar store, most of the optical stores which have optometrists and labs always can make custom eye glasses. You can go there and the optometrist will give you an exam and measure your size, then they will make glasses according to your prescription and size. Or you can order them online as long as you provide your prescription and size. However, I think you'd better buy the frames together with lenses because putting your original lenses into the custom made frames is difficult and that glasses cannot meet your need. Hope helps you.
