An omega-3 fatty acid found in fish, known as DHA, prevented age-related vision loss in lab tests, demonstrates recently published medical research from the University of Alberta. Faculty of Medicine & Dentistry researcher Yves Sauve and his team discovered lab models fed DHA did not accumulate a toxic molecule at the back of the eyes. The toxin normally builds up in the retina with age and causes vision loss. "This discovery could result in a very broad therapeutic use," says...

Just because a driver has passed the motor vehicle administration's vision test may not mean he or she is safe to drive. A recent study found that the frequency and distance at which drivers with moderate levels of blurred vision and cataracts recognize pedestrians at night was severely reduced, even when the drivers have passed the required vision test.

When people feel the onset of a migraine headache, they may head to a dark, quiet room to rest. This instinct may be sound: A new study suggests that even without the headache, migraine sufferers may process visual cues better in an environment with few visual distractions. In a study published in the April issue of Investigative Ophthalmology & Visual Science ("Visual Noise Selectively Degrades Vision in Migraine"), researchers from Scotland's Glasgow Caledonian University asked migraine...

With 30 million drivers in the US aged 65 and over, we count on older Americans to recognize when they can no longer drive safely and decide that it's time to stay off the road. A new study finds that a decrease in vision function is a key factor in bringing about this decision. The Salisbury Eye Evaluation and Driving Study (SEEDS), conducted by researchers affiliated with Johns Hopkins University, looked at changes in vision, cognition and the general health status of more than 1,200...
