People with eye diseases that damage the central vision can regain the ability to read quickly and conveniently using tablet computers (also known as digital tablet or simply tablets), according to a recent study.
This research has shown that people with moderate central vision loss could increase your reading speed in 15 words per minute on average. All study participants, regardless of their level of visual acuity, higher speeds reached their reading using a tablet computer backlit display.
The central vision loss affects millions of people with eye diseases such as macular degeneration or diabetic retinopathy, which damage the sensitive cells of the retina of the eye. The retina transmits images to the optic nerve, which in turn transmits to the brain.
When solution or mitigation measures as lenses, there is medicine or surgery longer effective, eye doctors to help patients maximize their remaining vision using devices that are often somewhat cumbersome to use. Before arise tablet computers, as close to people with vision problems were these loupes with lamp.
In the study, which was conducted at the Robert Wood Johnson Medical School, attached to the University of Medicine and Dentistry in New Jersey, United States, researchers found that the best results, with the same font size, were obtained using the iPad tablet.
The team of Dr. Daniel Roth believes the backlit display of the iPad is the key to the remarkable improvement in reading speed achieved by patients with moderate loss of central vision. Vision factor involved here is known as contrast sensitivity, which is the ability to see an object as separate and distinct from its background and to discern shades of gray.
The contrast sensitivity loss is common in people with low vision. The high contrast between words and background that can provide a backlit screen is a big advantage for these patients. The original Kindle, an electronic book reader created by Amazon and used in this study, does not have a backlit display.
