Know Frels®

Technical description

Frels come as a set of two end caps which can be slid over the temple tips of reading glasses or sunglasses.

Extending the temple tips and forming a curve towards the inside, Frels narrow the space between the temples, making it possible to rest the glasses around the neck.

Frels are made of high-quality polymers giving the product extreme flexibility in terms of elongation, tear strength and tensile strength.

Frels’ interior is specifically designed to suite several types of temples tips. A small hole at the end of the cavity releases air pressure when inserting the temple tip.

Frels have excellent biocompatibility for a safe skin contact and are manufactured in Switzerland in a ISO 9001 and ISO 13485 certified facility, in compliance with BfR, FDA and REACH regulations.
