Students have asked these similar questions
A clerk at the local grocery store wears glasses that make her
eyes look smaller than they actually are. Is the clerk nearsighted or
farsighted? Explain.
During LASIK eye surgery (laser - assisted in situ keratomileusis), the shape of the cornea is modified by vaporizing some of its material. If the surgery is performed to correct for nearsightedness, how does the cornea need to be reshaped?
A virtual image, we always say, cannot be caught on a screen. Yet when we ‘see’ a virtual image, we are obviously bringing it on to the ‘screen’ (i.e., the retina) of our eye. Is there a contradiction?
