Blue blocking glasses continue to disappoint

-


I have been consistent for the past decade when these first came out that it made no sense to block a specific color. We are finally getting some studies that back this up. 

Blue blocker study on eyestrain

I know many people with their $10.00 "blue light" lenses feel like it helps but the research does not show this to be true. This is all placebo effect. Any claim that blue light from screens is harmful is completely false. When you go outside you get 100,000 times the amount of blue light from the sun that you would ever get from a screen. 

Also, if you can see the color blue through your "blue light" glasses - what exactly are they even blocking?

If you want to reduce computer eyestrain, get glasses that properly correct your prescription if you need them. Every 20 minutes take a 20 second break from looking at your screen and focus on something at a distance. Make sure you are addressing anything that could be causing dry eye issues, such as fans or vents blowing on you. Invest in a quality computer monitor. We do have studies that show less strain and more productivity when the clarity of the monitor is better. Address overhead lighting issues. Fluorescent lights that flicker or lights that glare off your screen will contribute to strain. 

Ultimately the human body is not designed to sit in front of a screen for 8-10 hours a day. Get up and move around if you can, this will lower blood sugar and insulin levels, especially when done after meals. 

That is all for now, thanks for reading!

EAT YOUR WAY TO BETTER EYE HEALTH

Eat Your Way to Better Eye Health If you’re like most people starting the new year, you may have made a resolution to eat healthier in 2023.  Whether you’re starting to fall off the wagon or holding strong, it’s never too late to start eating well.  There are several vitamins and nutrients specific to the health of the eyes, and chances are, what is good for the eyes is also good for your overall health. 1. Vitamin A     - Required for the formation of rhodopsin, a pigment found in the retina that allows us to see in low-light        conditions.  Deficiency could cause "night blindness" due to impaired dark adaptation.     - Supports healthy functioning of surfaces in the eye like the cornea and conjunctiva.  Deficiency could lead to        dryness and corneal scarring.     - Good sources : orange-colored fruit and vegetables like carrots, sweet potatoes, cantaloupe, and apricots. Eggs   ...

Dangerous Generic Artificial Tears

-
  I hope everyone is having a nice weekend. I wanted to take a moment and talk about the recalled artificial tears that you may have heard about on the news. I have had a few calls from patients over the last couple of weeks about these. They are Ezricare non-preserved artificial tears and were recalled on February 2nd. There have been 55 reported infections with 5 people losing vision and one person dying. How can you die from an eye drop you ask... Eye drops, like all medications, are absorbed into the body as well as the eye. In this case the bacteria got into the blood stream and the patient most likely became septic, which is an infection in the blood.  These particular drops are not any I have ever heard of and I have never seen them locally. They are manufactured in India. The particular issue with these is that they are non-preserved so any bacteria that is in the bottle has nothing to stop it from growing. The photos of the drop seem to show a large bottle. The non-pr...
