What is blue light, and why should you care?

Most of us have an understanding that overexposure to ultraviolet (UV) light is bad for our eyes. We’ve learned to shop for sunglasses that have “100% UV Protection”. This is still good advice. However, due to a dramatic increase in our use of electronic devices and energy-efficient lighting, there’s increased concern about our exposure to another part of the visual spectrum... blue light.

Blue light itself is nothing new. It’s been present in natural sunlight and in artificial light in varying concentrations since the beginning of time. It’s actually very close to UV light in the visible light spectrum (Ultraviolet = 10-380 nm, Blue-violet = 380-455 nm). The difference is the level of exposure to blue light that we’re receiving in our modern world. The majority of this increase comes from our growing dependence on electronic devices, and how quickly this trend has occurred. Let’s look at a few dates that we can probably all relate to:

I was told I can’t wear contacts because I’ve got “a stigma”

Well, you don’t actually have disgraceful or defective eyes.  You simply have “astigmatism”, which is one of the more commonly misunderstood vision problems. Like nearsightedness (myopia) and farsightedness (hyperopia), astigmatism is a refractive error, meaning it is not an eye disease or eye health problem; it's simply a problem with how the eye focuses light.  Refractive errors are the primary reasons why people are prescribed glasses, contact lenses or pursue corrective refractive surgery.

It's nice how you said that contact lenses work like glades. I also like how you said that there are soft versions of them too. My... Read More
