How does blue light affect you?

Blue light affects us in two primary ways:
  1. It causes glare and can make it harder to focus.
  2. It has been proven to impact our sleep cycles.
By managing our blue light environment, many find greater visual comfort, reduced headaches and enjoy better sleep. This is the newest frontier in eye care. There is not much new information on how blue light effects us. Rather, it is our environment that has changed. In recent times, we have introduced many new sources of blue light. We have changed how we communicate and how we get our information. Almost everyone spends several hours per day looking at a screen of some type: reading from our phones, sitting at our computers or just watching TV. Additionally, many of us have high efficiency lighting. Generally speaking, all of these things are blue light intense.
In the past, orange lenses (commonly known as Blue Blockers) were used to combat blue light by improving contrast and increasing visual comfort. However, these types of lenses greatly skewed the wearers color perception and were often too dark for full time wear.
Today, the technology available allows us to very selectively reduce or eliminate specific nanometers (meaning, specific waves of light). Similar to lenses that block out ultra violet (UV) rays, blue light lenses block select parts of the visible blue spectrum.  By very selectively reducing certain blue rays, wearers can experience significant glare reduction and greater eye comfort with little change in color perception.
Selective reduction of blue light is important because although some parts of
