Silicone Eyewear Retainer Strap - Black

Silicone Eyewear Retainer Strap - Adjustable Non-Slip Cord for Sunglasses & Reading Glasses

With sweat-proof, salt-proof construction, it’s a small upgrade that saves big on dropped-lens repairs and replacements.

Interesting Facts About Eyewear Straps
- Silicone retains flexibility from about -40 C to +200 C, making it ideal for hot summer hikes and winter skiing
- The first retainer cords were invented by river guides in the 1970s to stop glasses sinking while rafting
- A 55 cm strap offers enough slack for quick on-off swaps but is short enough to avoid snagging on backpack straps
- Non-slip loops eliminate the pressure points some metal chain ends create behind ears
- Using a strap can extend frame life; fewer drops mean fewer scratched lenses and bent hinges
