Software Developer Thinks VR Caused His Eyesight to Degrade He's logged close to 10,000 hours of VR headset use since 2016 and has developed a new eye convergence problem that acts like dyslexia.

A recent government report found that one in 20 students may suffer from a childhood eye-muscle coordination problem called convergence insufficiency, or CI.

A 10-minute test using a handheld pupillometer and a questionnaire successfully picked up signs of mild traumatic brain injury in military personnel.

Convergence insufficiency is an eye disorder that affects vision when focusing on something nearby. To focus when you read or look at an object up close, your eyes need to turn inward together.
