I believe many computer repair technicians have ideas about what the geek squad charge for computer repair services or are unsure. I created this simple table which shows what services they do, and charge for. Everything is taken directly from their website.
Iris (anatomy) The iris (plural: irides or irises) is a thin, circular structure in the eye, responsible for controlling the diameter and size of the pupil and thus the amount of light reaching the retina. Eye color is defined by that of the iris. In optical terms, the pupil is the eye's aperture, while the iris is the diaphragm.
When the front part of the iris has pigment, it absorbs different kinds of light rays, and the light bouncing off the rear of the iris appears brown or gray. Often a person has blue eyes when young, and brown eyes later in life, because it takes the eyes time to produce pigment at the front of the iris.
