Yesterday, I went to an eyeglasses store and would like to get a pair of eyeglasses to protect my eyes from computer. I got ready to get anti-reflective coating. However, the CSR recommend anti-blue light blocking lenses to me. What's the difference between them?

The anti-reflective coating reduce reflections of light from the front and back surfaces. These reflections can tire the eyes. However, the anti-reflective coating cannot eliminate the glare/reflection completely. 

As to the blue-light blocking lenses,  they are specially designed anti-reflective lens coatings that reflect off the bad blue light (HEV or, High Energy Visible Blue Light) emitted by computer and tablet screens, as well as TVs and cell phones. These coatings allow beneficial blue light through to your eyes and reduces unwanted glare. They are designed to provide natural vision while protecting your eyes from harmful blue light, UV rays, and the effects of Computer Vision Syndrome (CVS).
