color blindness

While there are glasses that help compensate for red-green color blindness, the lenses often can't be shaped to users' prescriptions. That's why scientists are developing a new type of corrective contact lens, inspired by old gold-containing glass.

A new gene therapy treatment may be able to save the vision of patients with a blindness-causing genetic disease. DOA currently has no preventative or cure, but in tests in mice and human cells the team was able to slow progression of the disease.

The results of a first human trial testing a gene therapy for complete color blindness have been published. The data suggests the experimental gene therapy is safe, and potentially efficacious, opening the door to larger human trials in the future.

Contact lenses may be useful for restoring vision to short- or long-sighted people, but not so much at correcting color blindness. Now researchers from the University of Birmingham have developed a contact lens that can help correct certain kinds of color blindness, thanks to a safe, low cost dye.

​In most cases of colorblindness, people can actually see colors, but they have difficulty telling them apart. While there are glasses that help enhance contrast, they cost several hundred dollars. That's why two Microsoft software engineers developed a free iOS app that does much the same job.

Spectral Edge has unveiled a smart HDMI adapter that's designed to enhance the TV viewing experience for colorblind users, without significantly impacting what "color normals" see. The company is hoping to bring the product to market via a crowdfunding effort.

There may soon be help for red-green colorblind TV viewers. UK company Spectral Edge has announced its Eyeteq system, which reportedly "allows color-blind viewers to better differentiate between red and green when watching programs, allowing them to see details they previously could not."

The O2Amps glasses from 2Al labs that were developed to help read people's emotions can also assist people with color blindness.

EnChroma's Cx sunglasses are claimed to allow people with red-green color blindness to see red and green as distinct colors.

Online security expert Dan Kaminsky has developed and released a smartphone app which applies filters to images and video to help those suffering from color blindness to see colors that would otherwise remain invisible.

Research in ophthalmology has delivered promising results through a gene therapy that could safely eradicate color blindness based on the successful treatment of two squirrel monkeys with defective color perception.
