For those of us who spend 10+ hours a day on our computer, these glasses are a MUST.
Even if you don't spend huge amounts of time staring at a computer screen, these glasses will really help cut down the exposure to blue light AND thus, cut down on eye damage, eye strain and headaches. You will feel the difference after just a few hours of wear.
Do youself a favor, get a pair of these and experience the difference. It's like preventative medicine for your eyesight!
