Wearable Technology for the Visually Impaired

Share On:

For a large number of visually challenged or impaired patients, even the simplest of routine tasks may become challenging. Despite the range of medical and surgical procedures, a wide range of patients’ needs to depend on different technological aids for vision with varying success. However, times are changing and technology is improving. The new era is bringing wearable technology to the forefront. Specially and carefully designed to help people with low or lost vision, this eyewear allows access to activities that would otherwise be unavailable to those with vision problems.

Who Can Benefit?

Almost all patients with macular problems can experience vision improvements with these devices. In fact, any age-related macular disease or diabetic retinopathy may find this technology beneficial. However, it’s still not entirely adequate for glaucoma, retinitis, and pigmentosa.

Image Processing

The latest wearable technology for visually impaired uses a high-resolution camera and organic light-emitting diode (OLED) displays. The diodes are placed near the eye, producing a sizable 300 degree horizontal view. With the placement of the image close to the eye, advanced image processing is required to focus. Using special contrast and stabilization algorithms, the technology produces and filters the image through optical prisms found between the OLED displays and prescription lenses of the patient.

The Result

The resulting image is far clearer than what they usually see. This revolutionary technology improves acuity and contrast sensitivity in vision loss patients. Many patients report the shrinking or elimination of blind spots. Moreover, the fact that the images are placed at latency below 100 milliseconds minimizes the risk of nausea and vertigo. Wearable technology helps to restore vision to a significant extent in people struggling with vision loss. This portable, easy-to-use device will allow patients to carry out everyday activities with little or no difficulty.
