A strap lengthening arrangement for eyewear incorporating an extendable and retractable retaining strap in a hollow temple to form a part of and be attached to eyewear such as eye sight correction glasses, sunglasses, safety and protection goggles, and the like. The temple has a longitudinal passageway extending the length of the temple and an eyewear retaining strap, a moveable or traveling strap retaining block, and a block retractor are disposed within and along the length of the temple. The strap is arranged to fold back on itself first about a pivot positioned proximate the end of the temple and then again about a second pivot attached to or made part of the block effectively tripling the length of the strap within the temple. An improved block retractor and lock and release mechanism for the block are also disclosed.
