Your Eyes Instruction Manual Part 1
Channel: David Chia
Date: 2020-07-19

If your eyes came with a video instruction manual, then this would be the introductory segment.  This video goes over the four primary types of refractive error.  Naturally, given the rise in prevalence of myopia or nearsightedness, the video spends the majority of the time on this topic.  The video highlights what you can do to help protect your sight.  One key principle is that sunlight is the antidote to screen time.  And that we are only going to get better if we all know and do better.
