• What are computer glasses?

  Computer glasses are prescription glasses that are designed to wear when doing computer work. They allow you to focus your eyes on a computer screen, which is farther away than reading material is normally
  held. There are other activities such as for example playing piano(piano glasses) or shooting (shooting glasses) that also require a similar custom fitting. These specialty glasses called "task-specific"
  are designed to meet the visual needs of the activity. General purpose bifocals are not designed for computer work. They force the wearer to tilt the head back in order to focus on the screen while looking through the lower segment of the bifocal lenses. Such a forced
  position can cause neck and shoulder pain and it can also cause arm and
  low back pain. Depending on the individual's vision and type of
  work, there are several options while selecting computer-specific
  glasses, such as Monofocal ,Bifocal ,Trifocal and Progressive Addition Lenses (PAL) Source: http://www.ccohs.ca/oshanswers/ergonomics/office/computer_glasses.html

• What kind of sunglasses can eliminate black spots or "flies" of the vision?

  No. Sunglasses cannot remove black spots or "flies" of the vision. The black vision is also called floaters which are caused by the shadow of dead cells and fine aggregates of vitreous protein on the retina. So you can take a surgical procedure which is called "vitrectomy" to eliminate the black spots. The supplementation of Lutein Taurine is also a good way to remove the black spots, which helps regenerate tissues in the retina. However, I haven't heard that sunglasses can eliminate the black spots.

• Will the vision worsen if you don't wear glasses?

  It is ture. You should listen to what your doctor adviced you. When I was 13 years old, my vison got -1.00, then my doctor advices me to wear my glasses all the time, and I didn't listen to him, then when I go back to have the eye exam again 1 years later, my vision got -2.25. That really surprised me! Wear glasses all the time is good for your vision.
