HOW GLASSES SHOULD FIT?
The way you wear your prescription glasses and sunglasses and prescription shades online can have an impact on your eyesight and how much protection your eyewear offers. The right frame for protective eyewear is one you will use consistently, and learning how glasses fit your face can help with your overall comfort and satisfaction.
Your glasses fit your face best when sitting high enough up on your nose to not slip off but low enough to not push into your brow or forehead, additionally, your glasses frame width should align with your face width. The lenses of your glasses should be centered in front of your eyes so that your pupils are looking out of the middle of each lens. This rule applies both horizontally and vertically. Your eyes should not be too far up or down, left or right in relation to the lenses.
