How do I insert Frels® on my glasses?

To attach Frels®, you must insert the end of the temple tips into the insertion hole and press it slightly up and down by approx 5-6 mm (see attached photos). Sometimes moistening the Frels® makes insertion easier (Frels® are washable).

Frels® are flexible and can be expanded and adapt to the shape of most spectacle temple tips. Please note, however, as described in the e-shop, that they are not suitable for heavy spectacles, thick temples (over 8.0 mm) or very narrow frames (under 2.5 mm). For an optimal fit, please ensure that the distance between the ends of the glasses is no more than 9 cm.
