Quick fit answer: expect an easy medium.
Most styles sit around 51–52 mm lens width with 20–21 mm bridges, reading medium on many faces while the upswept edges add a gentle lift. If you’re between sizes, match the lens width you already wear within a couple of millimeters.
Sun comfort without the bulk
These tints take the edge off harsh midday light while keeping colors readable; branded sun lenses are non-prescription. In the Gemma Styles sun collection, clarity stays consistent across models, so pick by shape and size first.
Materials & care, made simple
Hand-polished acetate feels smooth and warms slightly to your skin, while the full-rim build keeps everything stable during long days out. Listings typically include a protective case or pouch - check "What’s included" on each product page before you buy.

FAQ
How do I read sizes like 52-20-140?
The three numbers are lens width, bridge width, and temple length in millimeters. For the same look, keep lens width within a couple of millimeters of a pair you already like, then choose the bridge number that matches how your current frames sit on your nose.
Do these lenses block UV?
Product pages list lens details. Many Gemma Styles models on this page note 100% UVA & UVB protection - compare the individual listings and colorways to confirm the exact lens information before you buy.
Will cat-eye frames suit my face?
Cat-eye shapes add a subtle lift that flatters round and oval faces and can sharpen softer features. If you prefer less upsweep, look for milder angles or slightly wider fronts to balance proportions without overwhelming your face.
Can an optician add prescription lenses?
Many optical shops can fit prescription sun lenses into full-rim frames. Bring the exact model and your Rx to confirm feasibility, thickness, and cost. Materials and curvature vary by style, so availability depends on the lens lab and the frame’s shape.
What comes in the box?
Listings typically include an original protective case or pouch. Always check the "What’s included" note on the specific product page to confirm accessories for that style and colorway before purchase.
How do these feel during long wear?
Full-rim acetate keeps things stable without feeling heavy, and the upswept edges distribute weight comfortably. For most medium fits, temple lengths around 140 mm sit securely without pinching; adjust at an optician if you feel pressure points.
