Blocking the protein PROX1 can help regenerate vision cells (such as photoreceptors in the retina) by lifting a developmental brake that normally prevents certain cells from becoming photoreceptors. Here's a breakdown of how this works:

Is self-powered artificial synapses a cure for color blindness? Self-powered artificial synapses are advanced electronic devices designed to emulate the function of biological synapses, enabling machines to process visual information in a manner similar to human color vision. These devices integrate optical sensing, memory, and processing capabilities into a single unit, allowing for efficient and adaptive visual perception.

Benito Daza de Valdes documented corrective vision in his books in 1623, considered the first book of optometry. In these books he addresses the properties of the eye and vision defects, corrective optical tools and dialogs between craftsmen and doctors.

Willebrord Snell was in fact the first person to document the relationship between the paths taken by light rays when crossing boundaries between two surfaces and their refractive index.

Cataracts are the clouding of the natural lens of the eye. Cataract surgery is considered one of the safest and most effective procedures in the treatment of this disorder. Find out what cataract surgery is and what you need to know. 

Braille alphabet is a tactile system created to be interpreted by the sense of touch. It was specifically designed to help those who suffer from vision disorders that severely impair, or even eliminate one's ability to read normally.
