Hi quality laser pointers are a must nowadays for presentations at seminars or conferences or even regular classroom teachings.  For one thing they make your life so much easier.  When making presentations it helps to emphasize and point out things on a screen without getting in the way of the projectors.  But with all the other colored laser pens available why choose a green laser pen?

Highest Visibility With the Color Green

The green laser is ideal because it is the most visible to the naked eye at low light levels.  It has been tested that for the same level of output the green laser beam always seem brighter at low light level. The human eye is most sensitive to the color green.  Ever wondered why the chalkboards at school or the stop lights are green.  They are designed that way because the eye is drawn towards the color green.  Studies have shown that the eye is 50x more like to seen green than any other color.  That is why when choosing a laser pointer you should always choose green.  What ever it is that you want to draw attention to, your green laser pointer will certainly attract more attention.

Where to buy?

Buying a laser pens are easier than you think.  Just doing an online search will get you massive results but I like Amazon.  I like them because they have practically everything and their site has reviews from previous buyers so you can get others experiences before you buy.  Amazon has just about any type of laser pointer you can get that is legal.  They have from the basic 5mw to the massive 500mw.  See below for a sample of their laser pointers.

Caution: If you don’t know already, anything that is more then 400mw cannot be advertised as a laser pointer because of it harmful effects.  Also, do not point laser directly at the eyes as any laser greater than 5mw can cause permanent eye damage within 10 seconds of time.
