Fitting 6, 8, 10mm Hinge

When fitting new lenses, we recommend high-index plastic (n=1.6), polycarbonate or Trivex.

The groove for metal frames will depend a little on the colour coating: for frames in eggshell, off white, desert, taubenblau and aqua the groove should be 0.65mm wide and the lens cut 0.03mm smaller all around.

For frames in all other colours the groove should be 0.6mm wide and the lens cut true to size. A correct fit ensures the perfect tension in the hinge and gives the frame the necessary stability: when a lens is cut to the correct size the space between the two sides of the hinge will be parallel:

4mm hinge

With the superfine 4mm hinge we streamlined the lens fitting process: you can now change the lenses without removing the temple. All you need is a little piece of ribbon or nylon, which can be ordered:

Fitting lenses -rubber

Fitting lenses into a rubber sunglass is simpler than you might think. It follows the same principles as fitting an acetate frame: the “pop-in” method, from front to back (from outside in).

Starting at the upper temporal corner, place the glass into the metal ring and then into the upper nasal corner; the top half of the metal ring should sit snugly in the groove. Continuing from the nasal corner in an anticlockwise direction, press the lens into the frame bit by bit until the it clicks into place back at the temple.
CLICK = IN.

Please note:
_The groove must be a little deeper than by other ic! berlin frames: 0.4mm (instead of 0.3mm) and between 0.6 and 0.65mm wide.
_To avoid chipping, bevel the rear/inside of the lens at 42°.
_As with metal frames, only use high-index lenses (e.g. n = 1.6).

Sun lenses

All ic! berlin sunglasses are fitted with super lightweight, super strong plastic lenses that offer full protection against harmful UV rays. Our sun lenses took the dropball test and aced it (F.D.A 21-CFR 801.410).

The table explains filter category levels of sunglasses but please note: the filter category is the amount of light allowed to pass through the lens and does not represent UV absorption.

If your sunglasses are fitted with polarized lenses please be aware of possible colour distortions or blackout with some LCD screens.
