Blue Light Blocking Lenses
While blue light has some benefits, it could also be harmful to our bodies. Blue light consists of light that has a short wave length but emits high energy. Sunlight is the main source of blue light which most of us get exposed to most of the time. Other sources of blue light include television, computers, smart phones, lap tops and LED Lights.
Evolution of modern technology has led to people depending more on electronic gadgets. In the recent years, children of as young as two years know how to operate a smart phone. It gets worse for adults who spend extended periods glued to their television watching or tapping on their smart phones. Prolonged exposure to these electronic gadgets can lead to constant headaches, blurred vision, and eye strain.
Over the years there has been an increasing number of reported cases of ocular complications due to blue light. This has led to the developing of Blue Light blocking lenses designed with a special coating that can reduce that. The coat can allow good light to pass through the lenses and prevent the bad light. It further helps in reducing screen brightness, straining of the eyes and blurred vision.
Blue light blocking lenses can also come in photochromic lenses that protect the eyes from blue light and also automatically darken in response to UV and temperature to act as shades and also protect against UV A and UV B.
The good thing with blue light blocking lenses is that they can also be used as regular eyeglasses to be worn throughout the day. This will help prevent direct eye contact with the sun or any LED light exposure.
There is a need to take precaution when exposed to blue light. Headaches or eye strain symptoms could be an indication that blue light is the cause, especially when using smart phones or other digital devices. I’s recommended to see your Optometrist for full examination and discuss those lenses as pertaining to your prescription and use. The doctor will further advise on whether it’s recommended for you to wear blue light blocking lenses. Blue light blocking lenses function in such a way that they prevent the harmful light from passing through the lenses to the eyes.
Digital devices have become very prevalent in our lives which means we are more exposed to blue light than ever before.
