Prescription eyeglasses are eyeglasses that have been prescribed by an eye doctor specifically for a person's vision needs. They are designed to help people see more clearly, especially up close, by correcting any vision problems such as nearsightedness, farsightedness, or astigmatism.
The prescription for glasses is typically based on a number of factors, including the wearer's age, gender, occupation, and specific visual needs. The prescription will include the specific power and range of the lenses needed to correct the wearer's vision, as well as any other special features such as anti-reflective coating or transition zones. How to read eyeglasses prescription?
Plastic frames often have no nose pads while metal frames have nose pads. When you choose glasses, you just need to make sure they fit your nose properly so that they can't slip down from your nose very often. So it depends on your nose size and shape.
There really is no rule but ideally, you want to pick a frame that will not completely cover your eyebrows. It’s good for the eyeglasses to be slightly below the brow line so that your eyebrows would still be visible when you use them as part of your facial expressions.
