The format of the measurement 53/35/22 stands for A/B/DBL,
which we have decoded for you below!
A: Represents the width of the lens, taken as the widest span across the lens.
B: Represents the height of the lens, taken from the top to bottom, at its maximum height.
DBL: This is the distance between lenses, and is taken at the most narrow point between lenses.
