Screen time & your eye health

Ever worried about your screen time and the effect it has on your eye health? You are not alone!
Many have wondered if the use of devices and the visable blue they emit increases eye strain, or has any effect on the development of eye conditions such as age-related macular degeneration (AMD) or glaucoma.
The Association of Optometrists have examined the clinical evidence of the visible blue light emitted from your devices and provided some advice to pass on:
  • There is no evidence that visible blue light causes eye disease in humans
  • Visible blue light filter coatings typically block up to 20% of blue light (as opposed to UV filters which can block close to 100% of UV light)
  • Using screens close to bedtime may contribute to poorer sleep, which can make a person less effective during the day
  • Turning off any digital devices up to an hour before sleeping can help aid sleep
  • Using night settings, if your device has them, can aid sleep by decreasing the amount of visible blue light emitted by the screen during night time hours
  • To avoid eye strain people should adhere to the 20/20/20 rule, every 20 minutes, look away from your screen at something at least 20 feet away for 20 seconds
  • Have a sight test every two years, or more often if your optometrist recommends it
