The Importance of Blue Light Blocking

Over-exposure to blue light comes with many negative effects, including headaches, eye strain, fatigue, and difficulty sleeping. The problem is that many of us have no choice but to sit in front of a computer screen for many hours a day for work. However, if you block blue light before it hits the eyes, the negative effects can be avoided. If you’re suffering from the effects of blue light overexposure in Katy or Hudson, TX, our optometrist at Eye Site can help.

The Truth About Blue Light and Electronic Devices

Blue light was always a major part of being outdoors, but today, it has invaded homes and workplaces. First, as a part of fluorescent lighting, LED light bulbs, and eventually flat-screen TVs. Then came the proliferation of the blue light-emitting display screens of personal devices like laptops, tablets, smartphones, and some smartwatches.  The time we spend staring into these screens and how close they are to our faces is much more harmful than the blue light from the sun. Many people suffer from eye strain, headaches, insomnia, and blurry vision as a direct result of blue light.

Optometrist Concerns

Blue light easily penetrates the eye and reaches the light-sensitive retina. When this happens, it can cause cellular damage and create changes in the eye similar to macular degeneration. This is why our optometrist recommends you wear blue light blocking glasses if you are spending six hours or more looking at a screen each day. There are also blue light blocking screens that can be placed over the displays of computer monitors and handheld devices.
