Why Most Luxury Sunglasses Require Continuous Tightening (And Peeqs Do Not)
Peeq Sunglasses Utilize Unbreakable Technology
Have you ever noticed that your glasses and sunglasses require continuous tightetning of the hinge screws?
Even the most luxurious sunglasses brands will feel loose every so often, until you take that mini screwdriver and tighten at the corners where the frames meet the temples.
That's because most luxury glasses and sunglasses utilize a material called cellulose acetate, often referred to simply as acetate.
Cellulose acetate is a bioplastic meaning it contains certain renewable biomass sources - in the case of glasses frames usually woodpulp and/or natural cotton fibers.
For those reasons, acetate offers various advantages, most notably its ability to produce a beautiful array of colors and havanas. However, acetate does contain plant fibers, which can lead to water absorption and subsequent shrinkage.
Essentially, your acetate frames are shrinking over time, ever so slightly, and hence requiring the tightening of screws and hinges in order to maintain a snug fit.
In an effort to produce to the most durable and verstaile glasses, Peeq opted against using acetate, and instead utilizes a Swiss technology thermoplastic referred to as TR90. TR90 is a form of nylon often called "unbreakable". To learn more about Peeq's frame materials, check out the article entitled "Glasses Frames: TR90 Nylon vs Cellulose Acetate vs Titanium".
