Abstract: An eyewear with a pair of light emitting diodes (LED) matrices is an apparatus that enhances the aesthetic appeal of the eyewear by illuminating different patterns and letterings with the pair of LED matrices. A left lens and a right lens each have an LED matrix, which traverse through and protrude out of their respective lens. Both LED matrices are electronically connected to a programmable microcontroller, which is able to turn on/off each individual LED in order to create the patterns and letterings on the LED matrices. The microphone and VU meter also allows the LED matrices to display patterns and lettering that relate to the music or sounds around the apparatus. Each individual LED for both LED matrices are properly spaced apart from each other so that visibility is not significantly reduced while wearing the apparatus.
