First of all the simplest and most commonly followed rule when using a green laser is "TO NOT " look directly at the beam with UNPROTECTED eyes. These protections are the safety goggles, looking directly at the laser's beam can cause retinal damages and can even cause temporary or even permanent blindness.
The next is "TO NOT TO POINT" your laser pointer to neither a human nor animals. Although pointing your green laser pointer to person or an animal is fun and looks like it might be safe, one must never point this device on either a human or an animal, this can cause slight burning or can even harm the eyes of the human or the animal being pointed at.
Lastly, "NEVER POINT" your laser pointer directly to any flying aircraft like airplanes and helicopters. This is a Federal offense and you can be put to jail for these actions. You must never do it.

Lens Cleaning for Laser Pointers - Tips and Instructions
One of the most common problems you can have with laser pointers and one of the easiest to fix is dirty lens. You can tell the lens is dirty when the beam point is spotted or out of shape instead of the normal small tight circle.
There are many ways to clean the lens of a laser pointer such as q tips, microfibre, cotton buds and alcohol solution. Some of these may work, others will not but they all run the risk of damaging the lens. There are only two methods of cleaning lens that work well AND will not damage the lens. Those two methods are using compressed air and using professional lens cleaning tools such as a lenspen.
Compressed air and lenspens
The most common sources of compressed air are cans of compressed air and hand pumps or squeeze bulbs. The main criteria for compressed air sources is the air must be clean and dry. This is one reason why blowing on the lens is not recommended.
The best professional lens cleaning tools are lens pens from the company lenspens http://www.lenspen.com These lens cleaning tools are safe and suitable because they are designed to clean fragile precision optics such as camera lens.
Instructions
Safety is always an issue with high powered laser pointers so the first thing you do before cleaning the lens is remove the batteries from the laser. After removing the batteries, leave the battery end cap off as an extra precaution.
Compressed air will be able to clean 90% of lens so try using compressed air first. Gently unscrew the lens cap and with the nozzle held two to three centimeters away from the laser, direct a flow of air onto the lens for several seconds.
Install the batteries in the laser and test the beam. It should now be clean. If it is not, remove the batteries again and use the lenspen.
First gently use the brush of the lenspen to brush dirt and debris off the lens then use the pad on the other end of the lenspen on the laser pointer lens for several seconds to clean and polish the lens.
By the end of this process, then lens will have been thoroughly cleaned. If there is still a problem with the beam point or beam, it may be due to damaged lens.

Does anyone know where I can get a cheap laser pointer that will stay on without holding down a button?
My cat loves to chase the laser pointer beam, but my hand gets tired from holding down the button. I don't want a fancy, expensive laser pointer, just something simple that can be turned on and off.
I just bought one of those laser beam level tools at Walgreens for about five bucks. The button clicks on and clicks off. I have yet to use it for its intended purpose. The cats seems to find it a lot of fun.
