There are several occupational lenses available, to relieve the strain of work related near tasks such as prolonged computer usage. Many people require clear vision at several different working distances, often using multiple screens from their smartphone to large computer monitors. Our Dispensing Opticians at Zacks London Eye Clinics can provide guidance on the most suitable occupational lenses for your specific lifestyle requirements.
In Europe, over 60% of 40 to 60 year-olds now use computers at work and at home. Computers have become an indispensable tool with most people spending several hours a day in front of a screen. The results are only to be expected: blurred vision, headaches, dry eyes and light sensitivity. Over 75% of computer users report these symptoms. At around the age of 40 they become aggravated by the normal decrease in visual acuity and accommodation capacity.
Occupational Lenses Designs
There are several occupational (computer) lenses designed specifically for the computer vision of presbyopes such as Varilux Computer and Nikon Online designs, each available with a variety of coatings. Recently new ‘blue’ coatings have been designed to specially enhance the contrast on digital screens and reduce the level of high energy blue light reaching the eyes.
Most occupational lens designs centre on the computer working distance. The largest, top portion of the lens is focussed for the computer screen distance with a smaller reading portion situated in the lower half of the lens. There are also occupational lenses available with a small portion at the top of the lens for distance vision. These are very different to varifocal lenses which have a much wider distance portion and narrow intermediate (computer distance) portion.
