So don't buy the cheap glasses from laserpenshop.com. Don't spend your money for inviting a doctor. These cheap anti-laser glasses is far not enough to protect your eyes from output power over 300mw. At leat it is dangerous to venture. After all, it is your eyes. I think, laserpenshop.com staff don't experience and test this for you.
But I do recommend a kind of good anti-laser glasses. It is also a new arrival of laserpenshop. It listed below:
