Using human retinal tissue grown from stem cells, researchers shed light on how color vision develops. The study found thyroid hormones dictated whether the cells became blue, green or red photoreceptors.
Researchers say children with visual problems such as amblyopia may face developmental issues in brain areas responsible for attention.
A new study reports the popular erectile dysfunction drug, Viagra, can cause long term retinal damage and color vision problems in men.
Researchers report a neural network called the isthmic system helps us to select visual objects that catch our attention.
Researchers have developed a 3D printed prototype for a bionic eye. The team successfully printed an array of light receptors onto a hemispherical surface. This advance could revolutionize restoring vision to those who have lost their sight.
Where objects appear in a person's visual field can affect the ability to determine what the object is, researchers say.
Researchers report blind people need additional timing cues to accurately judge relative locations of sounds, but those without visual impairments who were blindfolded could judge the relative location of sounds independently from timing cues.
Researchers provide evidence that the posterior parietal cortex plays a vital role in converting vision into action.
A new study reports spending more years in full time education is linked with an increased risk of developing myopia.
A patient missing most of her occipital lobes on both sides of the brain is helping researchers shed light on how the brain processes objects in motion.
A new study reveals how recognition and detection of basic emotions expressed by other people's faces alters when viewed centrally and in peripheral vision.
A new study reports that while we might not be able to see so well in the dark and are less than adept at distinguishing colors, humans can see in finer detail than most other animals.
