Unlike ball mice optical mice don’t retain any moving parts which which is why they mostly don’t have mechanical malfunctions and optical mice are more durable.

The light emitting diode (LED) of battery-powered wireless optical mice only glows steadily when movement is detected. The rest of the time it flashes every so often in order to save energy.

So what’s the difference between the optical mouse and the laser mouse?

In lieu of using a light emitting diode (LED) the laser mouse is supplied an infrared laser diode. The small infrared laser the mouse is equipped with principally increases the resolution of the photo made by the mouse. The laser facilitates for around twenty times greater surface tracking ability than conventional optical mouse technology.
