Jay,

a) If you've seen a prism (or the cover of Dark Side of the Moon), you see
that different colors are affected differently when they pass through glass.
The differences if these colors are the wavelength. I suspect eyeglasses are
designed to focus 'average' colored light. I also suspect they will not
focus radio waves.

b) The rods and cones in your eyes are not sensitive to radio waves. (Unless
there's something you're not telling us)

Okay, here's a weird one for the group: Radio waves are the same as light
waves, except they're not in the visible spectrum, right?

Here's why it matters: As we were departing from Muscatine, IA today (a
beautiful day to fly in the Midwest, BTW -- clear and warm) after a great
lunch, my gaze fell on their on-field VOR transmitter. Focusing closely
on
the "Hershey's Kiss"-shaped structure (with my new glasses -- wow, what a
difference a new prescription makes!), I wondered aloud if the lens in my
eye was at that moment focusing powerful radio waves onto my retina.

Mary, a scientist with a strong physics background, was not sure if radio
waves behaved the same as light waves.

I've never heard of anyone frying their retinas by looking at a radio
transmitter, but this begs the question: Can the lens in your eye focus
radio waves?

If not, why not?
