Adaptive Optics (AO) is a method for removing the blurring of images caused by changing distortions within optical systems. Turbulence in the Earth’s atmosphere causes blurring of astronomical images. In an analogous manner internal imperfections and fluids in the eye cause the image of the retina to be blurred. The use of the AO allows ground based telescopes to see as clearly as if they were in space, and these technique, when used to look at the retina of the human eye, dramatically sharpen the images of the retina.
