Online VES Autofocus Patient Manual
What is it?
The Ocutech Vision Enhancing System-Auto focus (VES -AF) is the first autofocus telescope system designed specifically for the visually impaired. Its high quality optics and 4x power magnifies objects from infinity to as close as 12 inches and keeps the image immediately and continuously clear. The VES -AF makes it easier for the visually impaired to see the blackboard in school, signs while traveling, computer screens at work and home, packages, labels and signs while shopping, and people at a distance, as well as many other applications. The VES -AF is worn attached to the top of an eyeglass frame which also contains the regular eyeglass prescription. Its light weight allows it to be worn comfortably for hours. A separate, rechargeable battery pack operates the system for an entire day.
Why is it important?
The visually impaired might benefit greatly from telescopic lenses if only they could be used easily. Telescopes must be refocused whenever one looks from one distance to another, especially at close viewing distances where even slight movements can blur the image. As a result, individuals find telescopic glasses inconvenient and difficult to use. Seniors often find it hard to learn to manipulate the devices. Students find it difficult to look at the blackboard, then watch the teacher, and then look at their desk. Computer operators can't easily look at the monitor, then switch to the keyboard, a printout or another worker. Autofocus removes the hardest part of using a telescope system -keeping the image clear. The VES -Autofocus provides the most natural, magnified vision currently available from any low vision device. It allows the visually impaired to perform visual activities much more efficiently and with greater comfort than ever before.
Who is it for?
Any visually impaired individual whose vision improves with magnification and who has very specific visual needs to see better for distance, intermediate, or near activities, might benefit from the VES - AF. Individuals who have found conventional telescope systems to be helpful but impractical may find the VES - AF to be the solution they have been waiting for.
How does it work?
Computer controlled infrared electro-measure the focusing distance many times per second while another computer controls a miniature motor that moves the focusing lens to the proper position. Special software helps to insure that the focus is prompt, accurate, and stable.
Does it really help? - National Eye Institute Studies
Pilot clinical studies have been completed at four independent low vision centers with funding from the National Eye Institute and the Ontario Ministry of Health. In total, 32 visually impaired individuals were asked to rate the VES -AF prototypes on a variety of visual tasks and compare them to their own conventional telescopic and reading low vision aids. Eighty-two percent (82%) rated the VES -AF either "good" or "very good" overall. Of great interest was their response when comparing the VES -AF to their own low vision aid for reading. While 56% rated their own device as "good" or "very good" for reading, 83% rated the VES-AF as "good" or "very good." In summary, both the subjects and the clinical investigators were enthusiastic about the promise of the VES - Auto Focus.
