1-CREDIT CARD METHOD:
1. Take a Debit/Credit card
This is the approximate width of a medium Eyeglass, Sunglass
2. Stand in front of a mirror.
Place one tip of the card on center of your nose and touch the other towards the edge of eye.
3. Now check the position of the card:-
If card extends beyond the corner of the eye , The Size Will be Small
If card roughly touches the corner of the eye , The Size Will be Medium
If card doesn't reach the corner of the eye , The Size Will be Large
2- IF YOU'VE EXISTING EYEGLASS:
You can easily found the size of frame by looking on the inside of your eyeglass temples (arm pieces). Below you'll find a quick guide to helping you identify your eyeglasses.
| Frame Size | EYEGLASSES | SUNGLASSES |
|---|---|---|
| Small | Below from 48 mm | Below from 55 mm |
| Medium | from 48 mm to 55 mm | from 56 mm to 64 mm |
| Large | Above from 55 mm | Above from 64 mm |
Measure horizontally across the entire front of the frame. Include any lug or hinge pieces that stick out on the sides.
Measure the lens vertically, at its tallest point. For bifocal or progressive prescriptions, the lens height must be at least 30 mm..
Measure horizontally, at the top of the bridge, from the edge of one lens to the other.
Measure from the hinge—where the arm connects in the front— to the spot where the arm begins to bend down around the ear. Then measure from the top of the bend to the bottom tip. Add the two sections together for the total temple arm length.
Measure the lens horizontally, at its widest point. Make sure the lens width accommodates your pupillary distance so that your eyes align with the “optical center” of the lens.
