The Story of our Superior Lens Technology

It Started 20 Years Ago

Tajima Direct™ co-founder Steve Rosenberg
left his executive position at Oakley™ to build on his idea
for a superior polarized lens technology.
He sourced the very best polarized lens maker
in the world – in Japan.
They had the secret black box recipe’s,
techniques and skilled craftsmen to manufacture
unique 30 micron-thin polarized film in specific tints,
while controlling polarized efficiency and light transmission
that no other lens maker could.

Then, Steve introduced his concept for a new, uncompromising
and superior lens material that offered the optics of glass,
shatter and impact resistant, durable, and extremely lightweight,
to be combined with specific glare-free polarized lens tints
for practical market-changing use and applications.
It was, at this time 20 years ago,
that our partnership began and ultimately,
our patented Tajima Urethane™ lens technology was born.

Since then, we’ve evolved
our technology, lens treatments and applications.
We’ve also now made Tajima Urethane
available to anyone – for any frame –
for prescription lens replacement
or sunglass lens replacement,
for the first time ever!
