Blue light from digital devices and the sun transforms vital molecules in the eye’s retina into cell killers, according to optical chemistry research at The University of Toledo. The process outlined in the study, which was recently published in the journal Scientific Reports, leads to age-related macular degeneration, a leading cause of blindness in the United […]
Declining eyesight improved by looking at deep red light
Staring at a deep red light for three minutes a day can significantly improve declining eyesight, finds a new UCL-led study, the first of its kind in humans. Scientists believe the discovery, published in the Journals of Gerontology, could signal the dawn of new affordable home-based eye therapies, helping the millions of people globally with naturally […]
Special filters in glasses can help the color blind see colors better
At least eight in 100 men (8%) and one in 200 women (0.5%) suffer from red-green color vision deficiency (CVD), totaling 13 million in the U.S. and 350 million worldwide. While those with normal color vision see in excess of one million hues and shades, those with CVD see a vastly diminished range of colors. […]
Limit exposure to LED blue light authority warns
While the use of LEDs is becoming more widespread for lighting and LED objects are on the increase, ANSES publishes the update of its 2010 expertise on the health effects of LEDs in light of the new scientific knowledge available. The Agency confirms the toxicity of blue light on the retina and highlights effects of disturbance […]
Researchers find infectious prions throughout eyes of patients with Creutzfeldt-Jakob disease
Researchers find infectious prions throughout eyes of patients with deadly sporadic Creutzfeldt-Jakob disease, a discovery that reveals both a biohazard and a potential diagnostic tool By the time symptoms of sporadic Creutzfeldt-Jakob disease (sCJD) are typically discovered, death is looming and inevitable. But, in a new study, researchers at University of California San Diego School […]
Irreversible damage to color vision linked to popular erectile dysfunction drug
In a first-of-its-kind study, Mount Sinai researchers have shown that color vision problems caused by retinal damage on a cellular level can result from a high dose of sildenafil citrate, the popular erectile-dysfunction medication sold under the brand name Viagra. The results demonstrate that excessive use of the drug could lead to long-term vision problems, […]
Turmeric-Derived Eye Drops Could Treat Glaucoma
A derivative of turmeric could be used in eye drops to treat the early stages of glaucoma, finds a new study led by UCL and Imperial College London researchers. In the new Scientific Reports paper, the researchers report a new method to deliver curcumin, extracted from the yellow spice turmeric, directly to the back of the eye […]
Eyeliner Application May Cause Eye Problems, Study Finds
People who apply eyeliner on the inner eyelid run the risk of contaminating the eye and causing vision trouble, according to research by a scientist at the University of Waterloo. This is the first study to prove that particles from pencil eyeliner move into the eye. Dr. Alison Ng, at the Centre for Contact Lens […]
Contact Lenses Alter Eye Bacteria, Making It More Skin-Like
Contact lenses may alter the natural microbial community of the eyes, according to a study published this week in mBio®, an online open-access journal of the American Society for Microbiology. In a study of 58 adults seeking outpatient eye care, researchers at New York University School of Medicine found that contact lenses make the eye […]
Light Exposure During Pregnancy Key To Normal Eye Development
New research in Nature concludes the eye — which depends on light to see — also needs light to develop normally during pregnancy. Scientists say the unexpected finding offers a new basic understanding of fetal eye development and ocular diseases caused by vascular disorders — in particular one called retinopathy of prematurity that can blind premature infants.
