Laser Mouse

A laser mouse is a type of computer mousing device that uses a laser beam rather than a ball to track the movement of the user's hand.

Users immediately began to sing the praises of the optical mouse, saying that it made mousing work much easier than traditional mice, and it is becoming increasingly difficult to find a ball mouse as a result.

A laser mouse, on the other hand, which is a type of optical mouse, is different because it uses a laser beam which is invisible, or nearly invisible, to the human eye.

In general, the laser mouse moves very smoothly and accurately, although if the system memory is bogged down, it will cause the cursor to lag, along with everything else. In addition, the laser mouse can reflect from almost any surface, meaning that a mouse pad is not necessary.

The light is uncomfortable so it might damage my eyes. i feel a slight numbness in index finger due to laser mouse excessive use. i use the index finger with my computer. dr arshad "With the introduction of a graphical user interface in the late 1980s, computer companies saw the need..."


I just stared into mine for a prolonged period. :) *Laser mouses are lasers, quit saying they aren't.* there is a difference between a laser and optical mouse and there is a difference between a laser emitting diode and a light emitting diode. laser mouses are class1 laser devices which cannot harm you even if you stare at it all day(A class 1 laser is safe under all conditions of normal use. This means the maximum permissible exposure (MPE)*cannot* be exceeded. This class includes high-power lasers within an enclosure that prevents exposure to the radiation and that cannot be opened without shutting down the laser.

Laser mice use infrared wave range, so you will not see any light because the most of infrared light would be absorbed by your cornea and lens. But it does not mean that laser mice are safe like LED.

Laser diode mice are new, relative to old LED mice. poster: '"Laser" mice do not actually use a laser.

Always worried about laser mice. actually laser mice use the same type as your tv remote, if you have the mouse opened up and look at the "led" you will see a small red dot which is the same what you have from your tv remote

Anon12000 - I don't know much about laser strength classifications, but I have read specs to certain brands of laser mice and they say that the mouse is safe, even though they are Class 1 laser products. Also, I think manufacturers build in safety mechanisms to protect against potential harm.


That said, it'd probably make sense not to put the mouse up to your eye! :) And just another interesting tidbit... Laser mice are 20 times more sensitive to surfaces than LED optical mice, meaning they can be used on more surface types than optical mice.

Look up some of the laser mice on the market, like Logitech and Microsoft, and you'll see in the specs that it includes a laser, not a LED. is the invisible laser light shining out of my mouse dangerous to the eyes?
