Why Does CJ Wear Glasses?

Eyeglasses are a marvelous invention. When they are matched to one’s own eyes, the results can be nothing but spectacular (which is related to “spectacle” which leads us to “eyeglasses”…language is nifty like that). My life would be so different without these wondrous bits of glass/plastic.

This is a Photoshopped approximation of what my computer screen looks like to me: with glasses on the left, without on the right; at a distance of about 75 cm (30″) — about arm’s length away. Some of the edge-detection compared to real life is missing, but with the slight doubling of the image it’s in the ballpark. (For the curious: I’m in the between -4 and -5 diopter ballpark, and getting increasingly “-” as the years go by.)

Now, at around 7 cm (about 3″) my vision without glasses is as sharp as the image on the left…and slightly magnified. It’s great for close-up work. Unfortunately, most of the world exists far beyond the tip of my nose. Without glasses, I’d be missing out on a lot.  I have to say that along with antiseptics, antibiotics, and analgesics, corrective lenses are the greatest of medical inventions.
