Swift Optical Offers Blue Block Lenses
Let us start with the infamous question: What is blue light?
Blue light is not a new thing. It is literally everywhere. In fact, the main source of blue light comes from our beloved sun, however there is both good and bad blue light for us.
Unfortunately, a significant amount of harsh blue light is emitted from our electronic devices, such as smartphones, tablets and computers. The human eye does not have the capability to block all blue light, which in turn leads to vision issues after prolonged exposure.
Almost all visible blue light passes through the cornea of the eye and the lens into the retina. Inevitably, this harsh blue light will cause eye strain, blurred vision, fatigue and headaches. Studies have also shown that prolonged exposure to the harsh blue light can lead to an increased risk of developing age-related macular degeneration. And if we know anything about macular degeneration it is that it leads to complete vision loss in the affected eye(s) over time and affect more Americans than cataract and glaucoma combined.
There are filters available for smartphones, tablets and computers that prevent significant amounts of blue light given off of these devices from reaching the eye.
Computer glasses can also be helpful in this area, both with or without a prescription. However, they are the standard yellow lenses and are not all that aesthetically appealing.
Our Blue Block lenses are made to order with your prescription and without the deep yellow tinting, making them both beneficial to your health and aesthetically appealing to be worn throughout your day to day activities. Our lenses block 48% of the harmful blue light from 380 to 500nm range and leave the good blue light unaffected, after all we need blue light to see our colors properly – like our sky!
