Sensitivity To Movement

• One of the main differences between laser and optical mice is the type of light they use to detect movement. Optical mice use a light-emitting diode (LED) while laser mice use lasers. The average laser mouse senses movement at around 2,000 dots per inch while the average optical mouse senses movement at 400 to 800 dpi.
  
  

Versatility

• Laser mice are more versatile and can function on almost any surface. Optical mice perform well on a wide variety of surfaces but have problems performing on black or shiny surfaces.
  
  

Application

• Both laser and optical mice are improvements over ball-mice and are suitable for average consumer use. Certain professions or hobbies, such as those involving gaming and graphic arts, make use of the laser mouse's higher sensitivity.
  
  

Price

• Laser and optical mice have roughly comparable prices, depending on manufacturer, ranging from less than $40 for basic mice to more than $100 for specialty mice for gaming and graphic arts.
