When selecting new eye glasses, it is best to note down the frame size from your old pair of prescription glasses if they fit well on your face.
Most of the time these measurements would be engraved on the inside of your eyeglass temples (arm pieces) or behind the nose bridge area. For instance, these will be in the form of 48-19-190 where the first number represents the size of the lenses, the second number is the bridge size and the third is the temple length, also known as the arm length. In some cases, your frame may display a fourth number which refers to the height of your lens.
Eye size is the horizontal width of the frame’s lens in millimeters. Usually, the eye size ranges from 40 mm to 60 mm.
Bridge size is the distance between the two lenses in millimeters and typically ranges from 14 mm to 24 mm.
Temple length is measured along the length of the temple from one end to the other and also includes the bend.
Your temple length can fall between 120 mm and 150 mm.
It is the vertical height of an eyeglasses lens which is measured from the tip to the bottom of the lens aperture of the frame. The B measurement is important for bi-focal lenses or progressive lenses.
Each individual has different facial features and require different frame measurements. Moreover, frames vary by their shapes and sizes. When you are purchasing a new frame, you can try on different frames using our online Virtual Try On feature until you find the perfect one. The Virtual Try On feature is a great way to see how the glasses will look and fit on you. In case you already have an eyeglass frame, you can refer to its frame size. These measurements don’t have to be exact but can vary from your existing frame size as follows:
Eye size: within 2 mm
Bridge size: within 1 mm
Temple size: within 5 mm
|Small||50mm and below||55mm and below|
|Large||55mm and above||65mm and above|
