The use and safety of the laser pointer

What is a laser pointer?

The laser pointer is a tool used to point to objects or places, and is defined as "measurement, leveling and laser product positioning" under FDA regulation. They are usually used in meetings, astronomical presentations, and laser Pointers in both mental and manual tools are also very popular. In recent years, laser designators have become readily available and are usually sold in hardware stores, animals, hobbies and office supplies.

Are laser Pointers safe?

When using the laser pointer correctly, the risk is minimal if they meet the laser power limit. Laser Pointers are abused when they are directed to the eyes or treated like toys. Aimed at the eyes of a laser designator light more destructive than looking directly at the sun. In addition, the striking effects of the beams used to drive cars or other machines could lead to serious accidents.

The FDA is concerned about the availability of various laser products that can be used under dangerous conditions. Green, blue and purple laser Pointers have special concerns. Although these laser designators have a legitimate purpose, they can be modified to be more powerful and dangerous if they're not used responsibly.

Is the brightness of the floodlights a good indicator of power and eye risk?

Never assume that the color of a laser beam indicates its power. Under the bright conditions (indoors or outside), a powerful laser beam may look the same or weaker as a low-intensity laser beam. In the photos below, for example, the green laser beam is much brighter than the red, much brighter than the blue. In fact, these lasers are also powered, and all three of these lasers are at the same risk as the eyes. If you see a bright blue or purple laser beam with a brightness similar to that of a green laser, you can think that the blue/purple laser is more powerful, and the direct fixation of the beam causes serious damage and direct eyes.

In general, you shouldn't look at any laser beam.

How to safely use a laser pointer?

Keep in mind that powerful blue laser is not toys and can only be used by adults or supervised by adults.

1. do not aim or illuminate the laser pointer.
2. only activate the laser pointer when used to point to nearby objects.
3. don't buy laser Pointers for your kids. Lasers are not toys.
4. before purchasing a laser pointer, make sure that the following information is included on the label:
   • Stating that it meets the provisions of chapter 21 CFR (federal regulations)
   • Manufacturer's name and date of manufacture
   • Warning against exposure to laser radiation
   • Category names, from category 1 to category 3. IIIb and IV products can only be used by properly trained personnel and should be used in applications where the high power products are legally required.

What is the FDA's role in regulating lasers?

FDA manages medical and non-medical lasers. The FDA may check laser product makers and demand that the recall do not comply with federal standards or radiological safety defects. The agency can also test laser products and check the display of laser shows to ensure public protection. The makers of the floodlights must tell the FDA that they are planning the fair, which can be inspected and acted upon if possible.

Is it legal for consumers to use a laser pointer?

Some lasers are strictly used by doctors, professionals or entertainers, and can only be used by properly trained and licensed personnel. The FDA requires labeling of laser products that include laser radiation and other hazard warnings, and says the laser meets FDA safety standards. The label must also indicate the product's power output and hazard rating. Consumer laser products usually belong to class I, class II and IIIa classes, while professional laser classes may belong to class IIIb and class IV.
