Eyewear Size Guide

Not sure what frame size to order? Every Sight Optics listing includes three measurements in millimetres, printed on the inside of your current frame's temple arm (for example 52-18-140):

• Lens width (the first number, e.g. 52mm) — the horizontal width of one lens.
• Bridge width (the second number, e.g. 18mm) — the distance between the two lenses, across the nose.
• Temple length (the third number, e.g. 140mm) — the length of the arm from hinge to tip.

How to find your current size

Check the inside of your existing frame's temple arm or the bridge above the nose — most brands stamp these three numbers directly on the frame. If you can't find them, take a pair that fits you well to any optician for a quick measurement, or contact us and we'll help you match a size from the model number on our product pages.

General fit guide

• Narrow face: look for lens widths around 46–50mm.
• Medium face: lens widths around 50–54mm.
• Wide face: lens widths around 54mm and above.

These are general starting points, not exact rules — frame shape, bridge fit and temple length all affect how a pair actually sits on your face. If you're between sizes or unsure, message us on WhatsApp or email sightopticspk@gmail.com with the model you're considering and we'll advise.
