High-tech Devices for Low Vision

IALVS is your network for specialized technologies

The number of people afflicted with low vision has grown and unfortunately, continues to grow. Yet fortunately, so has the number of technologies designed expressly to help people with low vision. And IALVS is proud to be your leading resource for all of these high-tech devices.

From start-ups to established names in the high-tech industry, many companies are exploiting the latest advances in mobile and imaging technology to enhance the lives of people with low vision.

Low vision, defined as having a significant visual impairment that cannot be corrected fully by any vision treatment (such as prescription eyewear, surgery, or medication), can be caused by various problems. Common ocular diseases that lead to low vision include glaucoma, macular degeneration, retinitis pigmentosa, diabetic retinopathy. In addition, brain injury caused by stroke, trauma, or a tumor can result in a loss of sight in your visual field.

Regardless of the cause of low vision, reduced eyesight affects people’s ability to perform and enjoy many everyday tasks, such as reading, driving, cooking, or watching TV. Sadly, too many of these patients walk out of their eye doctor’s offices believing that there is no way to improve their quality of life with low vision. The IALVS strongly disagrees!

The right light can improve vision

When vision is compromised, the right lighting conditions can make a huge difference in improving function when performing many different tasks. Often, people with low vision ask us for recommendations about the absolute best type of lamp and lighting to use. In response, there is no single answer to that question.  Everyone should use the lighting that works well for their needs. Our IALVS experts offer the following tips to help people select the most helpful, individualized lighting:

  • To improve contrast sensitivity (a common problem when dealing with low vision), choose lighting from the wide range of advanced LED illumination systems available. LED systems are ideal, as they can enhance contrast by correcting for various wavelengths, color perception, and brightness. Many LED systems are also dimmable to relieve eye strain.
  • Lamps with an adjustable fixture are essential, as they can be positioned close to and aimed directly on tasks in order to increase visibility and reduce glare. In particular, swivel lamps work well because they can be raised or lowered easily. Also, if one eye is better than the other, place the lamp on that side of your body, and move it so there are no shadows cast on the page in front of you.
  • Under-cabinet lighting is effective for cooking in the kitchen
  • Install extra lighting in hallways and on staircases to promote a higher level of safety in areas in which it is difficult to move around
