UV vs. blue light: Which is more dangerous?

October 16, 2014

We concluded the last blog with a question: Which type of light do you feel is more dangerous to your patients, UV light or visible light including blue light?

Of course, answers to questions can always be up for debate. My answer to this question is blue light, and if you answered UV, over the next few paragraphs I hope to change your mind.

Let’s start by discussing the damage UV light can cause the eye. Cancers of the ocular adnexa, pinguecula, pterygium and photokeratitis are all conditions known to be associated with or caused by UV light exposure. Likewise, long-term exposure to UV has been linked to cataract formation. However, all of these conditions affect the anterior segment of the eye and are generally treatable. Rarely do conditions such as these cause legal blindness.
