Like the rest of the SR4105 line, this pair folds down via a hinge built into the square plastic frame, sized at a 50mm eye and 140mm temple. The lens is UV400 polycarbonate, with tint choices spanning solid colors, gradients, mirror coatings, and a photochromic finish.

The matte coating on this version flattens the surface finish so it doesn't catch a shine the way a standard black frame does, and that lack of gloss also hides the light surface scuffs and fingerprints that build up on a frame you fold and unfold daily. It's the better pick if you want the black colorway without the upkeep of wiping down a glossier finish.

Frequently asked questions

Will my optician be able to fit lenses into this frame without issues?

Yes — the SR4105 uses a standard Square rim and groove that any local optician can glaze exactly like they would with any other frame, whether you need single vision, progressive, or reading lenses.

Can I just pop clear lenses in myself without going to an optician?

If you don't need a prescription, you can fit a clear CR39 lens into the SR4105 yourself along the Square rim's groove — this is an independent SR design, not a Ray-Ban or Oakley product — though an optician is recommended for anything requiring correction.

Is this just a Ray-Ban or Oakley shape with a different label on it?

The SR4105 is an independently designed SR frame — its Square shape takes inspiration from popular styles, but it isn't a replica of any Ray-Ban or Oakley model, and it isn't affiliated with either brand.

What material is the frame made from, and how sturdy is it?

The SR4105 is built in durable acetate or metal depending on the Square style, designed to hold up to daily glazing, adjustment, and wear at the optician's the same way any other everyday frame would.
