Explanation of the Measurements:
- Lens Width (mm):
- The horizontal width of one lens from edge to edge. Optical lenses are typically between 40mm and 54mm wide.
- Bridge Width (mm):
- The distance between the two lenses, measured at the nose bridge. This can range from 14mm to 22mm.
- Temple Length (mm):
- The length of the temples (arms) from the hinge to the end, which rests behind the ears. The length is usually between 120mm and 145mm.
- Frame Width (mm):
- The total width of the frame, including the space between the two lenses and the bridge. A comfortable frame width ensures the glasses fit well on your face without feeling too tight or too loose.
- Recommended Face Width:
- A general guideline for which frame size fits best for a particular face width (narrow, average, or broad).
How to Choose the Right Optical Frame Size:
- Measure your face to determine your ideal frame size.
- Lens Width: Look for frames where the lens width matches your face width.
- Bridge Width: Choose a bridge width that fits comfortably on your nose without pinching.
- Temple Length: The temples should fit comfortably behind your ears without causing discomfort.
- Frame Width: The frame should fit across your face without pressing against your temples or being too loose.
