VariMagnifiers

Progressive (multifocal) lenses having variable optical power addition in the region of 2.5 diopters is good suited for most practical cases of visual problems correction.

Progressive (multifocal) lenses having variable optical power addition in the region of 2.5 diopters is good suited for most practical cases of visual problems correction. But in every day life we frequently meets with necessity of precise vision of the smallest details of different objects (map reading, viewing coins and stamps, embroidery, quilting, sewing, etc.). For low vision patients suffering from macular degeneration and other serious vision impairments the more strong magnification of objects is need ( see for example There are many different visual devises intended for help with reading, close work and distance vision (strong reading glasses, hand and stand magnifiers, tabletop electronic magnifier, hand-held and spectacle-mounted telescopes and even variable focus telescopes). In the different areas of professional activity (surgeons, dentists, watchmakers, scientists, jewelry making, microfabrication, electronics, precision mechanics, etc.) people also needs in the clear vision of very small objects (see for example ).

 

Most of these products use a static (constant) optics that leads to different ergonomic inconveniences (specific working distance and working position, limited field of view, large weight, limited mobility and difficult in adaptation) which in turn cause physical discomfort. Devices with variable focus, as a rule, are based on the using of expensive electron-optical technologies of autofocusing, which demands the computer control and rather large consumption of electrical power. Based on our patented technology we designed universal autofocuse binocular spectacle-like magnifier (Fig. 8) which can be easily adapt for specific visual work of the concrete user without any change in appearance, weight and a design.

 VariMagnifier Our technology made also possible to create a universal spectacle-like telescopic systems (Fig. 9) for professionals and for low visual abilities patients. These telescopes have automatically variable optical power ( from 0 to 10 diopters) provides immediately and continuously clear, magnified vision from 30 cm to infinity. Telescopes easily adapts to visual abilities of specific user, have a large field of view, low weight and very comfortable design. With this device a person can move his head, easily shift attention from a near to far objects and as naturally as normally sighted individuals.

 

Summary. On the base of novel patented technology using elastic liquid filled lens the variable optical power devices was developed. The new technology is the technology of the cooperative interaction of adaptive optics and biological system of human eyes, using of native human reflexes for optical power control of the liquid filled elastic lenses. Visual devices which can be produced by this technology provides comfortable (non-strain) seeing of objects at any distances. The VariGlasses is suitable for operating any form of moving vehicle. Such non-strained state of eyes gives a good motivation for activation of all physiological processes in the biological system of vision. As the result person gradually gains the experience of normal visual work of eyes and as a result a good possibility to gradual rehabilitation of visual function. Three types of products as alterative to existing products are developed:

  1. VariGlasses — multifocal autofocusing eyeglasses for visual problems correction such as myopia and presbiopia and providing variation of optical power addition in the range of 0 — 2,5D.
  2. VariMagnifier — autofocuse binocular spectacle-like magnifier easily adapted to specific user and specific tasks.
  3. VariScope – autofocusing spectacle-like devise for low vision patients and professional needs necessity of precise vision of the smallest details of different objects.
