If the frame is comfortable to wear that’s a great start. There are a few other things to keep in mind: pupils should be near the center of the lens; lenses shouldn’t extend past the side of your face; eyebrows should not be inside the glasses; when you smile, your cheeks don’t push the frames up; frames shouldn’t slide down your nose. If a frame isn’t quite right there are a few adjustments that we can make, free of charge: if the frames are too tight or loose behind your ears; the temples are too long or too short; the temples are too tight or loose at the side of your face; the frames are crooked or slide down your face.
