It is not a question of Class 3 being "better" or "worse" than Class 2. Different classes are more suited than others for different applications. A Class 3 Laser is more powerful than a Class 2 laser, and so offers more opportunities to cause injury while being used.
It is very powerful, falling into the "3B" class. Classes were determined by levels that can cause a lesion. The UltraViolet laser is far more dangerous than the visible laser. In the visible range, a continuous laser classes are: Class 1: up to 0.39 mW. Class 2: 0.39 mW to 1 mW. Class 3A: of 1 to 5 mW. Class 3B: 5 to 500 mW. Class 4: beyond 500 mW.
Laser Safety procedures are often specific to a particular laser installation. In general, however, the following apply:don't look directly at the laser beamknow where the laser beam path isenclose the beam path as much as possibleensure that warning signs and labels are properly placednever point a laser beam at a personuse appropriate protective eye wear if exposure to a Class 3B or class 4 beam is possiblewear protective clothing is exposure to a Class 4 beam is possiblenever stare into a Class 2 laser beamensure that laser users receive adequate laser safety training
Check the label. If it is marked "Class II", "Class IIIa", "Class 2" or "Class 3R", it is safe. All of those have power less than 5 milliwatts. The "Class II/Class 2" pointers are the safest--they are limited to 1 milliwatt. Do not use blue or green laser pointers as toys, even if they are rated Class 3R.
Yes, a class 2 laser can potentially damage your eyes if you look directly at the beam for an extended period of time. It is important to always follow safety guidelines when working with lasers to protect your eyes from harm.

Class 2 lasers can cause eye damage if directly viewed for an extended period. Safety precautions include wearing appropriate eye protection and avoiding direct eye exposure to the laser beam.

The human eye has its greatest sensitivity around 555 nm (540 THz), in the green region of the visual spectrum. This makes green lasers appear to be brighter than other lasers of the same power but different color. go to this site you can get from 1mw all the way up to 1000mw's on this site have fun and you be on this site for a long time they build good inexpensive laser's. here is the site and sure fire are good battery's they use them. laserpointerpro.com
