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.
High power lasers can cause serious and irreversible 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 has become increasingly regulated to decrease the dangers of lasers.
Laser safety goggles work by employing a polymer containing dyes that block light over a particular range of colors or wavelengths. For example, some safety glasses will block light with a wavelength of 500nm to 540nm that offers protection from green lasers.

With laser safety goggles, quality depends on two points. How well they block light at a certain wavelength and how much visibility they provide. The higher the OD, the more light that is blocked.
If the OD higher than 4, visibility while wearing the safety glasses will be too diminished.
After several seconds exposure to a laser beam, the dyes in the glasses will be ruined and the glasses will no longer provide protection.
Lasers are used in many applications as a consequence of the property of being both concentrated and highly directional. We even use them in the supermarket, as the checkout scanners contain lasers that read the bar codes on our purchases.

Semiconductor lasers are used as the reading and writing sources in laser printers, CD players, and DVD players. Cutting, welding, and blasting of tough materials are often accomplished with the support of gas lasers, which project a sharp, intense light. And laser fiber optics are often used to transfer data on the internet.
In the health care industry, lasers are used in eye surgery, cancer treatment, and ulcer removal. In these treatments they act as a more accurate scalpel, making tiny incisions to attain its target. The incisions are clotted and sealed immediately on account of the burning action of the laser. In cosmetic uses, they are utilized to remove tattoos, hair, and many types of skin discoloration.
