Do not allow minors to use a laser pointer unsupervised. Furthermore, only allow adults to use laser pointers after they have understood the responsibilities and risks that it carries.
-
2
Never shine a laser pointer at anyone, especially their face. Even temporary exposure can cause significant damage to the eye. Laser pointers are designed to point at inanimate objects.

3
Always be conscious of where you're pointing. Avoid pointing a laser at any reflective surfaces. Unintentionally reflected beams can easily violate Step 2.

4
Never use your laser pointer in the vicinity of airports, highways, construction sites or anywhere individuals need to constantly pay attention to their work for their own safety. A split-second distraction--a sudden laser light in a plane cockpit, for example--can be disastrous.
-
5
Be especially cautious around high-powered lasers, like green laser pointers used for stargazing. They are far stronger than the red pointers commonly used during lectures. And do not purchase a laser pointer at all if it does not identify its class or power.

how about a nice pair of laser safety goggles or glasses, then you don't have much to worry about. No better way to protect your eyes than blocking specific laser frequencys like green at 532nm and blue at 473nm , red at 650nm and so on. Some cool laser shades look good to and will do the trick.
