To know the size of your reading glasses, follow these steps: 1. Measure Temple Length by measuring straight to the end of the temple. 2. Measure Nose Bridge Size (DBL) at the narrowest point between the lenses. 3. Measure Lens Width at the widest point in millimeters. Accurate sizing ensures a comfortable fit.
Next, measure the distance between your pupils. This is known as the pupillary distance (PD). Hold a ruler against your nose. Close one eye and note the measurement from the center of your nose to the center of the open eye. Repeat for the other eye. This step ensures that the glasses align correctly with your vision.
Then, consider the frame size. Glasses typically have three key measurements: lens width, bridge width, and temple length. Lens width is the horizontal width of each lens. Bridge width is the distance between the lenses. Temple length refers to the length of the arm that rests on your ears. These dimensions guide you in finding a pair that is comfortable and attractive.
With these measurements in hand, you can confidently explore different styles of reading glasses. The next section will discuss how to select the right frame style based on your face shape and personal preferences.
