Researchers say children with visual problems such as amblyopia may face developmental issues in brain areas responsible for attention.
Researchers have developed a cornea implant from the collagen protein of pig skin. The implant restored the vision of 20 people with diseased corneas. The new implant could be a viable alternative to human cornea transplantation.
Meta-analysis reveals those who have visual impairments or are blind have a higher risk of mortality compared to peers with better vision. The study found mortality risk was 29% higher in those with mild visual impairment and rose to 89% higher for those with severe visual impairments.
Researchers investigate advances in BCI and consider the implications of linking our brains up to technology.
A new study reveals a possible cause of visual impairment in astronauts.
Researchers find those who are blind from birth visualize numbers the opposite way around from sighted people.
Cognitive tests that rely on vision-dependent tasks may skew results for up to 25% of adults over 50 with undiagnosed visual problems such as AMD and cataracts. This may lead to a misdiagnosis of mild cognitive impairment in older adults.
Smoking marijuana affects several key visual functions, including 3D vision and contrast sensitivity. However, 90% of cannabis users believe the drug has either no, or minimal, effect on their visual abilities.
Providing free or low-cost vision care and eyeglasses to children helped improve academic performance and behavior, researchers report.
Researchers discover those who were born blind use a brain map, similar to that in people with full vision, to distinguish between objects.
Researchers report human echolocation works in tandem with other senses to help deliver vital information for those with visual impairments.
Researchers have developed a new "brain window" that allows for longer-term studies to map the visual areas of the brain.
