Lens Size: 62mm Glasses

The matter of selecting the correct shape and style of glasses becomes personal. But when in doubt about which frames to choose from, some general principles may give you a lit bit of guidance. The principal determinant has one's face shape because it's the determining factor in getting a pair of spectacles to match perfectly. For example, square and rectangular glasses should be preferred for those with chubby faces. Oval or round frames usually look good on people with rectangular faces. Rectangular glasses are the best choice for triangle-shaped faces; if your face happens to be of a universal type, go crazy with any trendy frame you fancy.

Once you have decided on the shape and model you prefer, remember fitting size for optimal wearing comfort. This is the second major consideration when choosing a new pair of optical spectacles or sunglasses. The company usually notes the possible sizes on the inside of the left temple of the eyewear: you would see a set of numbers that outlines three dimensions, namely, the lens width, distance between the nose bridge, and length of the temple arm. For instance, if your first number is 62, you're looking for a pair of glasses with 62mm lens widths. Figuring out the frame size is really quite simple: just take the first number, multiply by 2, add the next number, and the last bit is about the hinge joints, which add for about 4 to 12 mm. Compare the width of your face against this total to ascertain whether a particular frame can fit.
