10 things you should know before you get new glasses

Photochromic: (Transitions, Xtra Activ, Vantage, LifeRx)

Lenses adjust to changing light conditions going from clear indoors to as dark as sunglass in bright glaring sunlight, automatically. Protects from distracting, discomforting and disabling glare. Blocks 100% UVA and UVB radiation. One rarely mentioned fact is that regular transitions don’t change much behind the windshield of a car. Xtra activ does change behind the windshield of the car but doesn’t truly ever become clear. Perfect lenses for someone who is outdoors often.
