For demonstrative purposes in retail scenarios, spectacle frames are fitted with what is called demo lenses. This is done to simulate corrective lenses, simply to give you an idea of what the frame will look like in a more realistic aesthetic. The lens demo uses the master optician as a template for fitting quality lenses at the request of the customer.

Anti-reflective coating (also called "AR coating" or "anti-glare coating") improves vision, reduces eye strain, and makes your eyeglasses look more attractive. These benefits are due to the ability of AR coating to virtually eliminate reflections from the front and back surfaces of your eyeglass lenses. 

Blue light blocking lenses have filters that block or absorb blue light. Natural blue light from the sun helps keep you awake and regulates your circadian rhythm. But indoors, unwanted blue light is emitted from digital devices such as computers and smartphone screens. 

Photochromic lenses are eyeglass lenses that are clear (or nearly clear) indoors and darken automatically when exposed to sunlight.  

Sun non-prescription or prescription lenses tinted sun lenses without coating. Sun lenses with polarization or anti-reflective are the best protection from glare and eye strain on sunny days. These lenses have a special filter that block bright reflections of light from water, sand, pavement, and automobile hoods and windshields.
