The idea of improving the capabilities of the human body is one of the main driving forces behind different types of technology today, and more so if the senses fail due to an accident or as a result of aging or illness.
In a recent experiment, 51 participants were made to wear a head-mounted low vision device called eSight. They reported quick improvements in their visual ability, better facial recognition and how they handle their day-to-day tasks, this according to a report published on healio.com.
These participants were aged 13 to 75 years, and had visions ranging from 20/60 to 20/400. Information was gathered first with the group not wearing the device, then as they were fitted with the device, and finally after daily use within a span of three months.
The eSight Eyewear’s magnification drastically improved the participants’ ability to read print at distance, gaining seven lines from baseline up to the intermediate measure. This was also true for them being able to read at near, which gained a five-line increase. After three months, there was another gain of one line. There was also an immediate improvement in critical print size and reading accessibility index, as well as in contrast sensitivity that registered a gain that equaled 12 letters, although researchers noted that there was no more change after three months.
Walter Wittich, Ph.D. and assistant professor at the School of Optometry at the University of Montreal, stated, “In the context of the rehabilitation of low vision using head-mounted assistive devices, such as eSight Eyewear, the individualized refraction installed inside the device and provided by an optometrist is key in the fitting of the device.”
The study showed that the headset was able to duplicate the effects of conventional corrective glasses, with the “magnification and contrast enhancement functions immediately [having] their intended effect.”
