Entry Twenty-Seven: I Wear Glasses Yall

We just took our test on lenses. I hope that Doc posts our updated grades soon . . .

I wear glasses because I have myopia, or nearsightedness. This means that I cannot see objects that are far away due to an imperfection of the lenses of my eyes. The light that enters them converges at a point that is slightly in front of the retina, where the light should converge to. So, the lenses of my glasses refract the light before it enters my eye so that the light can converge right on me retinas. The lenses of my glasses are diverging.

That is all.



Notice the delicate curvature of my spectacles . . .
