Scientists are figuring out why so many diseases and conditions, including diabetes, inflammation and parasitic infection, can affect our eye health. But there are ways to protect your macula.
A thinning of the retina is associated with earlier ageing of the brain. Widely available retinal imaging could help detect cognitive decline in its earliest stages.
Neuroscientists tackling the age-old question of whether perceptions of color hold from one person to the next are coming up with some interesting answers.
Kids need to play outside for a number of reasons, but there may even be benefit for their eyes. Here’s how sunlight helps prevent nearsightedness, or myopia.
