Yeah, but it's the quality of the material that you have to pay for. The
best liquid crystal material shaped into the size of a lense will set you
back about $1000. The better the material the faster it can switch states
(opaque and clear) and the greater the diversity between the two states (ie
the darker and the clearer the material gets, respectively). To be able to
go completely opaque and back to completely clear in 1/60th of a second or
faster is quite a feat!
