Adjustable cameras are equipped with an iris diaphragm, a device located in or near the lens and consisting of thin overlapping leaves that fold together to create a hole of continuously variable size. In this way the aperture, or lens opening, can be adjusted to admit more or less light as required.

The AcrySof® IQ lens is transparent yellow -- the color necessary to filter blue light. The patented yellow tint does not alter the natural colors of the things you see or the quality of your vision.
