SeawiscopeSpectacleRetainer is a strong, durable lanyard of elastomeric synthetic fibers.
On top of all the functional features of ordinary spectacle retainers, it has been specially designed for outdoor activities, in particular for water-sports, including scuba diving.
It has a section of 5 mm diameter. The standard size has a loop length of about 76 cm (30 inches). This length fits most people nicely. A modest size, loop length about 66 cm or 26 inches, is also available for those needing a shorter lanyard.
SeawiscopeSR is equipped with an adjustable slide. A slip-fit frame attachment goes over temple ends (earpieces), holding the eyewear securely. It is flexible and fits almost any eyewears.
A loosely fitted lanyard around the neck rests the eyewear at chest level when it is not in use, handy for those who put on and off spectacles frequently.
For vigorous sports, the lanyard may act as a headband with appropriate slide adjustment. This keeps the eyewear stable and snugly in their optical position.
