Usually developing slowly over time, many cases of glaucoma are only picked up during routine eye tests, by which time lasting damage may already have been caused. But this could change in the future as academics from the U.K. and Türkiye have developed a contact lens which can detect changes in eye pressure which signal possible glaucoma.
