Low vision E-glasses, namely wearable or headsets low vision eyewear assist the visually impaired to live a normal life by improving their visual performance and enriching their daily experiences. Low vision E-glasses are widely used for patients with varied eye conditions diagnosed with age-related macular degeneration AMD, retinitis pigmentosa, myopic macular, retinal detachment, diabetic retinopathy, etc.
Both virtual reality (VR) and augmented reality (AR) low-vision eyeglasses use the built-in camera to collect images from the outside world in real-time and then sent them to the display area of the eyewear. The software that these E-glasses use can zoom in, zoom out, and alter the acquired pictures, which enables these E-glasses can serve as low-vision aids.
Augmented reality (AR) E-glasses help people with low vision, peripheral vision or central vision loss, and allow people to see everything around them. In a study of patients with retinitis pigmentosa and genetic degeneration condition, AR E-glasses were applied to improve their mobility with a grasp performance improvement of 70% and mobility improvement of 50%. High-tech AR smart glasses, such as the Acesigt series, etc. apply assistive technology in improving the natural senses with the manufactured systems developed to accurately project bright light to correspond with the surroundings and the user's retina. In addition, most AR E-glasses have a simultaneous location and mapping technology, that enables the glasses to render 3D structures for the field of view in real-time.
Virtual reality (VR) low-vision glasses use the handset embedded in the screen, which shows the users an immersive world when they wear them. VR low-vision glasses for persons with low vision help them gain visual independence even with acuity eyesight between 20/100 and 20/600 and a 10 degrees field of view angle. This means that the functionality of the low-vision VR E-glasses is similar to that of binoculars which simulate the surrounding and remaining photoreceptors, helping the mind to collect more visual information and achieve an all-out functionality for the vision. Besides, most headsets that use VR technologies utilize head tracking technologies that allow the users to look at their immediate environments by moving their physical selves or their heads.
According to the system's design, most VR Acesight headsets have fully enclosing designs that cover the eyes of the users and thus do not assure them freedom of movement. But AR low-vision glasses have a pair of small display modules in front of the eyes, which ensures a large peripheral vision – it offers the users a clear vision and field of view that allows the users to monitor the surroundings and the things within the peripheral vision and guarantees users comfort and safety. The lenses of VR low-vision glasses are similar to the screen of a mobile phone, but each lens of VR low-vision glasses is a distinct display area.
Low vision E-glasses are ideally suited for legally blind or visually impaired individuals. Depending on the visual situation, legal blindness happens when persons with visual problems have a central visual acuity of 20/200 or less (Read more WHO Definitions of Low Vision). In addition, individuals with the following conditions could use wearable low-vision glasses as prescribed by their ophthalmologists:
• Age-Related Macular Degeneration (AMD)
• Myopic Macular (MM)
• Diabetic Macular Oedema (DMO)
• Central Serous Retinopathy (CSR)
• Macular Hole (MH)
• Lebers Hereditary Optic Neuropathy (LHON)
• Retinal Vein Occlusion (RVO)
• Punctate Inner Choroidopathy (PIC)
• Diabetic Retinopathy (DR)
• Stroke-Related Sight Loss
• Stargardt Disease
• Macular Dystrophy
• Inverted Retinitis
• Corneal Opacity
