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.
A new retinal implant that works in conjunction with camera-equipped smart glasses and a microcomputer provides blind people with "artificial vision" by stimulating retinal cells.
A new neuroimaging study reveals brain patterns that differentiate between men and women are less pronounced in non-heterosexual people. The differences occurred primarily in sensory processing areas of the brain, in particular areas associated with visual processing. Researchers say the brain differences could be linked to a genetic predisposition for same-sex sexual behaviors. The study reveals a neurobiological basis for same-sex attractions.
A new, lasting consequence of COVID-19 infection has been identified. Researchers report they have identified significant abnormalities in the eyes of those with severe coronavirus infection.
X-Rite Capsure, an archaeological tool to help researchers match colors, is not as consistent or accurate as the human eye in color determination.
IndCl, a drug that improves myelination and reduces motor disability, appears to improve visual problems associated with multiple sclerosis.
Our ability to pinpoint the exact size and location of objects varies from one person to the next, and even within our own individual field of vision.
Using artificial intelligence and neuroimaging, researchers have identified a link between mental imagery and vision. The brain uses similar visual areas for mental imagery and vision but uses low-level visual areas less precisely for mental imagery than vision.
