Digital Devices, Blue Light and Your Eyes

Greetings everyone! I am back again to inform you about some of the hot topics within the realm of "all things optical".

Today we are going to discuss blue light and how it can affect our comfort, vision, and eye health, both short term and long term. We will also touch base on some of the things we can do to help mitigate any potential threat to our eyes caused by blue light.

Blue light makes up a portion of the visible light spectrum. Blue light is a problem because it has a very high energy level that can penetrate all the way through to the back of the eye. This high energy light has the real potential to do damage to the sensitive tissue and nerves that are found in this region of the eye. This type of unimpeded blue light exposure can cause issues that can range from visual fatigue which can include increased incidences of dry eyes and blurred vision, to serious retinal damage later on if left unchecked.

Where is the exposure to blue light coming from? In the not too distant past, the vast majority of our exposure to blue light was from the sun. Enter stage left, "the villains that have increased our vulnerability to the damaging blue light"……..Digital Devices! That’s right, our phones, laptops, iPads, monitors and T.V screens emit high energy, potentially damaging blue light. Now I am sure that ALL my readers do not spend hours every day viewing one form of digital screen or another. However, I have heard that vast numbers of Americans in the U.S. are doing just that! Shocking I know.

The question is posed, how can I best protect myself from the possible damage of blue light? Well, the most obvious is to reduce screen time with a special mention for the kids. Studies have shown that the longer an individual is exposed to blue light, the more likely that issues will arise later. Screen filters are available for some devices which limit the amount of blue light that reaches the vulnerable parts of the eye. Eyeglass wearers can also benefit from lenses and lens coatings that help reduce the amount of blue light entering the eye. This is where IVO Eye Center comes in!

If you are concerned about the negative effects of blue light and want to protect yourself as best you can, call or come by and I will be happy to discuss the options available to you.

As always, thanks for reading!
