• What are spring hinges glasses?

  The regular glasses need your both hands to put them on. Sometimes your left hand is occupied by other stuff, and then you will feel troublesome because you must use both hands to put on your glasses. However, the spring hinges glasses can help you put your glasses on with one hand. The springs embedded at the meeting point of the frames and temples will push the temples right at place, erect and firm, at the lightest motion you give them. Such convenience is only shadowed by their enormous durability.

• 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 size of lens should I choose for progressive glasses?

  Unlike with bifocals and trifocals, which really require large-size frames, the use of progressive lenses allows many eyeglass wearers to choose smaller frames; the technology involved in progressive lenses already makes it possible to have enough space for the glasses' nearer area for reading and the farther area for looking at a distance. Although larger frames generally allow for better optical coverage, the person preferring a smaller frame can be accommodated; the eye care professional can measure the frame and lenses to determine the kind of progressive lens that will work best in the specific smaller frame preferred.
