416. When you look through the outer side of your eyeglasses, sometimes out of the corner of your eye, you can see a light star like all the light came together and lit up. Why do we see this? Where does it come from? Is it reflected light?
I'm not sure what effect you are observing. I do not see it myself. However, different types of lenses behave differently, so my nearsighted correction may not behave the same way yours does. There is certainly a reflection problem in some glasses. Although the main beams of light passing through the lens are handled well, internal reflections or reflections from behind the lens are not handled properly. They can form strange patterns of light on your retina, such as the light star you mention.
