Here’s a new school rule that kids can get on board with.
A study published in Ophthalmology showed that incorporating 2 hours of outdoor time was able to reverse the progression of myopia in school children.
Tell me about the study.
As part of the Taiwan School Student Visual Acuity Screen, students in grades 1 through 6 had their uncorrected visual acuity checked every 6 months. These data from more than 1 million kids were collected each year from 2001 to 2015. The research team found that from 2001 to 2011, the prevalence of myopia increased from 34.8% to 50.0%. Because of this, they initiated a program in 2010 that encourages schools to incorporate 2 hours of mandatory outdoor time.
What did they find?
They found that the prevalence of myopia decreased from 49.4% to 46.1% between 2012 and 2015.

WHAT YOUR PATIENT MIGHT ASK YOU
Is eye rubbing really that bad for you?
Well, it's definitely not great. According to a study published in Cornea, eye rubbing was the top behavioral risk factor for keratoconus development. The study included 202 patients with keratoconus (average age of 32) and 355 controls. Researchers collected data regarding eye rubbing, pattern of eye rubbing, dominant hand, allergies, history of dry eye, screen time, sleep position, and night-time work.
What did they find?
Eye rubbing, particularly rubbing with knuckles, showed a strong correlation with keratoconus. Additional associations were identified, which may merit future investigation as risk factors, including sleep position, night-time work, and screen time.
