Computing Lenses

Computing lens


Many computer users over the age of 40 who wear glasses have a problem with getting sharp focus on the screen in front of them. The reason for this is that distance lenses will carry our focus beyond the screen and reading lenses will focus before reaching the screen.

So, many of us using bifocals, raise our heads to look through the reading portion, which may initially seem satisfactory. However, after some time of intense computer work and subconciously trying to focus we have tired eyes.

Varifocal wearers have the same problem, with the intermediate section in such a small area of the lens you have to drop or raise your head by trying to keep your eyes in focus through this small section.



We have found the answer to this is a high quality single vision lens with power compensated to give sharp focus to the computer screen for any ophthalmic prescription we receive, suitable for plus or minus lens wearers. This gives a larger area of lens to look through, always in focus. The lenses are fully coated for anti-reflection/glare.

Please note:
These lenses are not suitable for outside use.

If ordering frame and lenses complete we need to know the distance between your eye pupils. The way to achieve this is to stand approximately 30cm in front of a mirror wearing your regular glasses, and with a marker pen accurately dot the pupil of the eye you are looking into, then do the same with the other eye. The actual reflective distance will be eye-to-screen distance.

Measure the distance between the two dots in millimetres and send this measurement to us with your prescription. We will do your lens centres from this.
