All GEEK EYEWEAR is 100% ophthalmic quality, which means you can take any frame you buy from us to
your favorite eye care shop or optical lab and have your own prescription lenses installed. Not all frames
are 100% ophthalmic quality but ours are. This means you are getting the same quality glasses you
get from your local eye doctor.
All GEEK EYEWEAR are brand new frames, mint condition, uncirculated, never worn before.
These are not ratty old glasses that smell, have turned green and have been used for years by other people.
All GEEK EYEWEAR is hand made from sheets of acetate. These are not cheap injection-molded car wash
glasses designed to look old.
All GEEK EYEWEAR frames are supplied with “Plano” (i.e., zero prescription power) CR-39 optical lenses.
There are three (3) main reasons we offer this upgrade for no charge:
1. Most glasses (without prescriptions) purchased on-line are supplied with acrylic demonstration (“demo”)
lenses
2. Demo lenses are designed to be thrown away when an optician cuts and installs a prescription pair of lenses
3. Even though they have no power and are clear, demo lenses are not designed to be worn or used.
They have a lot of distortion and aberration and will strain your eyes.
So we supply all our frames with CR-39 "ophthalmic quality,” lenses (the same lenses you get from the eye doctor.
If you wear your Geek glasses for fun, with no lens vision correction, our CR-39 lenses won’t hurt your eyes!
CR-39 refers to the material that is used. It is an optical grade plastic polymer recognized for its light weight,
chemical resistance properties . CR-39 lenses are the most common type of lenses used in the eye care
industry world wide.
CR-39’s impact resistance is greater than glass but CR-39 should not be considered for applications where
impacts are prevalent such as playing sports and motorcycle riding for example.
