Why video magnifiers?
The vast majority of people who require these devices are seniors with central vision loss, in most cases macular disease. Many people reach a point where optical magnifiers provide limited help. Video magnifiers accomplish a number of things.
- Variable Magnification
- Video magnifiers provide variable magnification. The user can easily change the degree of magnification to suit his or her needs.
- Image Quality-The Most Important Priority
- Magnification is only one component involved in aiding vision. In choosing a video magnifier, image quality should be the top priority. This is accomplished with an excellent lighting design, top quality CCD cameras and LCD monitors which are matched to the lighting and camera in order to achieve the highest level of contrast and brightness possible. it is also imperative that brightness and contrast can be controlled to match the needs of the visually impaired person.
Products offered by AdaptiVision provide the highest brightness in contrast in the industry. The brightness of a video monitor is measured in units called NITS. Most products offered by AdaptiVision have a minimum NITS rating of 500. These products incorporate a sophisticated CFL which results in uniform illumination with minimal glare. The Generation 2 Clearview + products from Optelec, use the proprietary Reon camera which offers excellent image quality and character smoothing under high magnification. - Peripheral Viewing
- While macular degeneration darkens central vision, peripheral vision usually remains intact. The movable tray on many units offered by AdaptiVision enables the user to optimize the field of vision in which he or she sees best. By sliding the tray, the customer can read faster and often at smaller magnification levels than initially anticipated.
