BLUE BLOCKERS By Dr. James Ivanoski, Optometrist at Madison Medical Eye Care with offices in Mequon & Saukville, Wisconsin

Blue blocker glasses are a hot topic in eye care.  These amber tinted sunglasses reduce glare and protect the eyes from ultraviolet light (invisible radiation from the sun that causes sunburn) and visible blue light.

For years we have known that ultraviolet light (invisible radiation from the sun that causes sunburn) can accelerate age related eye problems like cataracts, skin cancer, and macular degeneration.  We recommend that everybody wear sunglasses (including blue blockers) when outdoors to protect the eyes from ultraviolet light.

Now studies are being done on visible blue light and the effects on the eyes.   There is no conclusive evidence that blue light from hand held devices and computer screens damage the eyes in the same way that ultraviolet light does.  Our computers and phones are not causing macular degeneration and cataracts.  We do not recommend specific blue blocking glasses for computer use, but sometimes a light amber tint may improve comfort (reduce eye strain and glare) when viewing a computer screen.

The blue light from computers and hand held devices has been shown to affect sleep cycles.  It is recommended to avoid screen time 1-2 hours before bedtime.  Lack of sleep affects overall health including eye health

Eye strain and dry eye are worsened by excessive screen time.  It is recommended to take a break from computer work every 20 minutes to look at a farther away object for at least 20 seconds.  Blue blocker glasses are a good thing since they also protect from the harmful ultraviolet light, but are not necessary for looking at computer screens or phones.
