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.

What are Laser safety procedures?

Is a red laser pointer dangerous for cats?
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.

How far can a laser beam travel?
It depends on what colour it is, the type of laser it is, the output level, the quality of the optics and the media it's travelling through. In a perfect vacuum, they'll travel much longer than through atmosphere. For example, green lasers travel further than red or blue. Class 1 and 2 lasers have an output power level of <5mW. Class 3 can go up to 100mW. See related link.
