Moorfields Eye Hospital and University College London Institute of Ophthalmology researchers have examined 36 artificial intelligence (AI) tools for eye care approved by regulators in Europe, Australia and the US. The review, which was published in npj Digital Medicine, found there was significant variation in the amount of evidence that was provided on the clinical performance of the devices.

Scientists from University of Electronic Science and Technology of China have developed a contact lens that can simultaneously monitor intraocular pressure (IOP) and eye movement - even when the eyes are closed. Describing the technology in Microsystems & Nanoengineering, the researchers highlighted that the stretchable design of the contact lens enables it to conform closely to the curvature of the eyeball.

Scientists from Queen's University Belfast have used ultrawide-field imaging in patients with Down syndrome to identify early signs of Alzheimer's disease in the eye. Writing in Alzheimer's & Dementia, the researchers outlined how they performed ultra-widefield and optical coherence tomography (OCT) imaging in 24 people with Down syndrome and 17 people without Down syndrome. Both groups of study participants were between the ages of 27 and 53.

A new two-step approach to testing the colour vision of train drivers will enhance both the safety of the railway and its inclusivity for people with mild colour vision deficiencies. A report commissioned by the Rail Safety and Standards Board found that the new protocol for mainline train drivers would reduce the severity of colour vision loss in the most affected applicants who pass the new test three-fold.

Scientists from Tokyo University of Science have created a device that mimics human colour vision using solar cells that can differentiate between different wavelengths of light. Writing in Scientific Reports, researchers explained that the device incorporates two different dye-sensitised solar cells that can distinguish between different colours with a resolution of 10 nanometers. Rather than requiring a power source, the device generates its own electricity through solar energy conversion.
