Unexpected Cause of Double Vision: Rare Bone Cancer Diagnosed Instead of Screen Strain 🎗️

A man who went to his local optician with double vision he thought was caused by looking at his screen too long was diagnosed with a rare bone cancer.

David Ly, 44, was suffering from double vision in January 2020 but put it down to computer vision syndrome - eye problems caused by prolonged computer use.

The double vision persisted for one week and after colleagues urged him to get his symptoms checked he went to his local optician.

The optician at Specsavers was unable to find any problems with David's vision and urged him to visit A&E.
