Abstract

A spectacle lens will be made to focus at approximately 20-24 inches. This is an approximate, recommended viewing distance for a PC Monitor. The lens can be produced in several different magnifications (e.g. 1.00, 1.50, 2.00, etc.).

Description

Description There are a large amount of ready made spectacles on the market that are made for reading. These are made to focus at approximately 14 inches, making them suitable for books and newspapers, etc. <U>My invention</U> is to produce a range of spectacles with an average focal point of 20-24 inches approximately, suitable for viewing the PC Monitor Screen.

Claims (1)

  1. <U>Claims</U> My invention enables people to purchase ready made glasses, suitable for reading PC Monitor Screens. The key factor to my invention is the focus distance (20-24 inches approximately). This differs greatly from the already available `ready made reading glasses' that focus at 14 inches.
