Product Description
Many different devices emit visible blue light. This can include all of our electronic devices, such as smartphones, computers, and tablets, as well as LED bulbs with high (5,000+) Kelvin temperatures. Blue light can be quite bad for our eyes, and visible blue light can penetrate our eyes, back to the retina, potentially causing damage to the retina. Blue light can also effect our sleep cycles and our circadian rhythms. Blue light blocking glasses help block the dangerous light emitted by electronic devices and high Kelvin temperature LED bulbs. This can help reduce eye strain as well as help protect the eye.
Our blue light blocker glasses can either come with no magnification, or can also be selected in +3 and +4 reading powers. Black frames measure 5.4" from outside temple to temple, and the lens measures 2" at their widest point. Spring hinges help them keep their shape.
