What Are Blue Light Blocking Lenses?
Before the widespread use of mobile devices, computers, smart TVs, and an assortment of Internet of Things devices, the term “blue light” was something physics students worried about more than the average person. Fast forward to today, and the average person in an occupation probably deals with at least 12 hours a day of exposure to some kind of blue light through devices, and that doesn’t include what people already get from a simple walk out in the sun. At Lavenburg Medical Group in DelMar, we provide a variety of lenses, including blue light blocking lenses.
What Is Blue Light?
From a technology perspective, blue light consists of blue light waves. It is sourced from the sun, light bulbs, and digital devices. Under normal conditions, the typical person gets enough of it daily while being outside, and then their melatonin kicks in when the sun goes down and it’s time to sleep. However, with the go-go-go world, we’re hooked to devices for far longer. That means people are being exposed to artificial blue light used to illuminate their devices for hours on end and well into the night. This includes everything from smart TVs to reading tablets.
What’s the Impact?
Based on a number of studies, blue light has been definitely associated with eye strain after excessive daily work. “Computer eye” is definitely a condition an optometrist sees a lot of today. There are options to switch computer screens to red light formats after hours, but most devices need to be manually set, and TVs don’t typically make this easy. Prolonged viewing of blue light screens seems to create a noted risk for retina burnout, which of course is the critical part that translates images to the optic nerve and brain.
Blue Light Blocking Glasses
Specifically designed with filter lenses that either absorb blue light or block it entirely, these eyeglasses are a direct approach towards reducing blue light exposure for those who have to or want to keep utilizing artificially lit devices regularly. While some UV light does still get through, the eyeglasses contribute heavily to reducing blue light exposure and related eye strain, which is definitely a positive, especially for those putting in 12 and 14-hour days online or connected.
