I presented a discussion of these devices in an separate article: Low Vision Telescopes for Distance, Intermediate, and Near as Low Vision Aids Non-Visual Assistance OR Cam Optical aids permitted for driving are the bioptic lens systems. None of the electronic/digital glasses used for low vision enhancement are approved for driving. Can these electronic glasses be worn while driving? This technology is more of a virtual reality, immersive experience. Another option is to have the electronic glasses stream TV or videos onto the screens of the device. Choose a high-speed camera and high-definition OLED screens. The quality of the images is dependent on the camera and screens. Television watching: How important is the ability to watch TV or stream videos? One way is to watch TV is as a magnified image through the glasses. Consider it may also involve a data use contract (Most of us have already been down that road with our personal cell phones.) The downside is that they need, in many cases but not all, to have an internet connection. There is a plus side to smart phones as a part of the unit because it greatly expands the functionality of the assistive device. Learn more about this technology: Electronic Technology: OCR, TTS, and STT Computer software recognizes text within an image from the unit’s camera and is then able to translate it into words spoken through the unit’s speakers. OCR/TTS is an abbreviation for optical character recognition and text-to-speech. Other methods are using Bluetooth hand-held remotes or control by utilizing an app on a smart phone. They are controlled either by touch pads on the unit or by voice commands. They are most often color inversion, like white text on black or yellow text on black or inverted black text on yellow, or blue and yellow text combinations.Ĭontrols: Many of the units are hands-free, self-contained units. Many offer a cord to attach to an external power source or include additional rechargeable batteries.Ĭolor modes are contrasting modes to enhance the image, especially applicable to reading text. A continuous video stream will last about two hours, intermittent use without using special functions, it may last longer. These times depend on how the unit is being used. Most last 2 to 3 hours, some claim 4 hours. (Discussed below.) Two other creators have added field expansion and high contrast features to their electronic glasses Acesight and IrisVision Inspire.īattery Life: These units run on rechargeable batteries. OxSight out of the UK makes OxSight Crystal. One company has designed glasses specifically for field expansion and high contrast for these patients. Those with retinitis pigmentosa, advanced glaucoma, stroke patients, and those with degenerative retinopathies will benefit from this technology. These glasses are designed specifically for those with significant visual field loss. I would like to add a third smaller category called field expansion smart glasses. Those with severe vision loss benefit from non-visual assistance. Non-visual assistance does not require the user to have usable vision, but provides orientation, navigation, and object identification by auditory cues. Those with central vision loss benefit from increased magnification. Vision enhancement utilizes magnification and is best suited for those with some residual vision.
