(STUDY FINDS) — BIRMINGHAM, England — So many people, especially young people and teenagers, spend a significant period of time each day staring at a screen of some kind, whether that be a computer, smartphone, tablet, or the regular old TV. Now, a new study is warning parents that all that screen time may be behind a stunning rise in children who need prescription glasses.

According to the report released by United Kingdom-based eye care company Scrivens Opticians, the percentage of 13-16 year olds in the U.K. who need glasses has nearly doubled over the past seven years — from 20% in 2012 to 35% in 2018. Two-thirds of those teens were diagnosed as being myopic, or short-sighted.
