typical laser power density threshold that causes flash blindness is 100 μW/cm2 and prolong exposure at that intensity can cause permanent eye damage. Derive laser power density at the retina surface, for a laser beam with an initial beam waist, w 0 distance, d from the eye. Assume w0 =1 mm, λ=500 nm, and emmetropic eye calculate as a function of laser power ranging from 1 mW to 10 Watts, the eye-safe threshold distance from the laser source. Assume aperture of retina is 4mm in diameter and circular
