Rigid LONG Clear or Black
A solid choice for extra spectacle slipping stopping power. RIGID; made of allergy-free rigid silicone which doesn't stretch much. The aperture (the hole in the middle of chassis which your temple tips slide through) is about 4mm. At most, it stretches to about 7mm. (Slightly more if you warm them up a bit first by dropping them into hot water for about 30 seconds.) As such, it's ideal for temple tips that have a cross-sectional diameter of about 4-7mm; the kind of temple tips one usually finds with metal or thin plastic frames. This is in contrast to sunglasses temple tips which measure at 10-12mm. LONG means that the hook portion (the part that goes over your ears to stop your spectacles from moving forward) is long compared to the hook lengths of other models. It works great in stopping your glasses from slipping and is very comfortable when worn, but unlike a short hook which when worn is almost unnoticeable, long hooks aren't inconspicuous.
