Everyone else has focused (!) on wavelength, but no one has mentioned
radiated power.

That's because the question was "does my lens focus the radio waves", not
"is my retina being cooked".

There have been cases of people getting their eyeballs and other body
parts "cooked" by exposure to strong RF, particularly microwaves, due
to the same principle by which your (duh) microwave oven works. Tissue
damage occurs because of simple heating of molecules of matter from
the sheer raw power of the RF, not due to any "focusing" of
wavelengths.

The eyes, due to the high water content, are especially susceptible to
such damage.
