Press Release Summary: High power lasers can cause serious and permanent damage to a
persons eyes so laser safety glasses are an essential accessory. The glasses need to
match the wavelength of the laser, provide suitable protection and adequate
visibility.

Press Release Body: High power laser pointers and laser modules are both
entertaining and widely used for a large number of applications. There is just one
serious problem though with the spread of high power lasers. High power lasers can
cause serious and permanent damage to your eyes in less time than it takes to blink.
Governments and health organizations are aware of this and use and ownership of
lasers is becoming increasingly regulated to reduce the dangers of lasers.

The best solution though to the danger of high powered lasers is laser safety
glasses or goggle for eye protection.

Laser safety glasses work by using a polymer containing dyes that block light over a
specific range of colors or wavelengths. For example some laser safety glasses will
block light with a wavelength of 500nm to 540nm which provides protection from green
lasers.
With laser safety glasses, quality depends on two points. How well they block light
at a certain wavelength and how much visibility they provide. The ability to block
light is determined by optical density or OD for short. The higher the OD, the more
light that is blocked.

For most applications the preferred OD is from 3 to 4. If the OD is lower than 3,
not enough of the laser beams energy is blocked. If the OD higher than 4, visibility
while wearing the safety glasses will be too impaired.

Laser safety glasses are designed to protect users from accidental exposure to laser
beams not deliberate extended exposure. After several seconds exposure to a laser
beam, the dyes in the glasses will be destroyed and the glasses will no longer
provide protection.
