Adaptable to your prescription How to choose your glasses size
Choosing the right size for your frames is crucial when buying glasses online. Fortunately, this process can be simplified with our guide, designed to help you find the perfect pair of prescription glasses with ease.
Determine your frame size
The perfect match between you and your glasses starts with knowing the right size. At Seecly, we’ve simplified size understanding by using letter codes (S, M, L, etc.).
Measure the horizontal width of your current frame between the two hinges to determine your size.
- Check the size chart available in the size guide on each product page.
Understanding lens size
Lens size is expressed in millimetres and printed on the frame. For example, RB3013 2144 52 □ 16 means the lens width is 52 mm. This measurement directly affects the overall size of the frame.
- <50 mm = small size (S)
- 51–53 mm = medium size (M)
- 54 mm = large size (L)
Other frame measurements
Bridge width
The bridge width, measured in millimetres, indicates the distance between the two lenses. For example, "16 mm" in RB3013 2144 52 □ 16 represents the bridge size. This measurement plays a key role in comfort.
- Bridge size: 16–22 mm
A larger value means the lenses are further apart.
Temple length
Temple length usually ranges from 120 to 150 mm. It is less critical as the end of the temple arms can be adjusted.
Only corrective lenses are eligible for reimbursement. Second-hand frames currently do not have LPP codes and are therefore not covered.
Inside your package, you'll find a treatment form for your corrective lenses. To be reimbursed, you must send this form and a copy of your valid prescription to the CPAM, which will forward it to your mutual insurance.
