Love it or we make it right

The optical-grade lens opticians use, hard multi-coated.

The optical plastic opticians use for prescription work, set in a clean rectangular frame. The surface stays properly flat rather than carrying the faint bend a moulded lens has, and the multi-coat keeps reflections out of your own eyeline.

Materials

CR-39 lenses — optical grade, where most fashion frames use acrylic
UV400: ultraviolet filtered right across the range
Hard multi-coating: the hard layer resists scratches, the multi-coat kills internal reflection
An anti-reflective finish, which is why the lens reads deep rather than mirrored from outside
Plastic frame, flat across the brow

Details

Lens 58 mm across, 38 mm deep
Rectangular frame
32 grams net
CE certified
Five colourways: Obsidian, Honey Tortoise, Soft Pebble, Deep Cypress, Rose Petal

The same three numbers printed inside the arm of any pair you already own — compare directly.

Fit

Best for medium-wide faces

How to care

Microfibre and water only — solvent and alcohol wipes take multi-coatings off
Rinse first, so the cloth carries nothing across the lens
Case them when they are off; the coating is hard, the frame less so
Fold the same arm first each time and the hinges stay square

UV400 Protection

Lenses rated to filter UV wavelengths up to 400 nanometres — UVA and UVB covered.

Why this pair

UV400 rated

Filters UV wavelengths up to 400 nm — both UVA and UVB. The rating is what counts, not the tint.

All-day comfortable

Balanced weight and smooth contact points — designed to be forgotten while worn.

Chosen with intent

Every SRVR frame earns its place in the range before it earns a place on your face.

Made for rotation

Built for daily wear — the pair by the door, not the pair in the drawer.

Common questions

The most reliable trick: take a pair that already fits you and read the three numbers printed inside the temple arm — lens, bridge, and temple length in millimetres, like 52-18-140. Staying within a millimetre or two of your usual lens and bridge width keeps the fit familiar. Compare those against the measurements shown above where listed — and if the fit is off on arrival, 30-day returns cover the swap.

Yes — these carry a UV400 rating, meaning the lenses are designed to filter UV wavelengths up to 400 nanometres, covering both UVA and UVB. Worth knowing: tint darkness has nothing to do with UV filtering — the rating is what counts, and this pair has it.

A polarizing filter cuts glare bouncing off flat surfaces — roads, water, car bonnets — so colours look deeper and your eyes work less in hard light. One thing to know: polarization is a comfort feature and separate from UV rating — one doesn't imply the other. Our polarized pairs carry it in the name; if polarization matters for how you'll wear these — driving, time near water — email us and we'll point you to the right pair.

Email info@theservir.com within 30 days of delivery with your order number. The pair must be in its original condition. We'll take it from there.

Rinse grit off with lukewarm water first, then dry with a microfibre cloth — never a shirt hem, which micro-scratches lenses over time. Store them in a case, lenses up, and keep them off the car dashboard: trapped heat is the fastest way to warp any frame.
