I was offered eyeglasses frame with an add-on sunglasses, attachable
with magnets. There are magnets (pretty srong !) on both eyeglasses
and sunglasses frames. I am wondering, is it Ok to have such strong
magnets so close to the brain, pretty much all the time ? How old is
this magnet add-on technology ?

Been around at least ten years. I am not aware of any evidence that
magnets near the head cause problems.

Bowden in his "Faster Than Thought" book reported that Charles
Babbage stuck his head between two very large electromagnetic poles
and saw "visual effects" (i.e., sparks). But that was presumably a
very strong field.

Dear Don,

And then Babbage said, "...boy, that does not COMPUTE".

Maybe I can design a "differential engine" that will.

And the rest, as they say, is history.

Brains operate on chemical and electrical basis. Magnets are neither
chemical nor electrical and produce no energy unless moved over a wire.
Unless you have wires in your brain and regularly wave your glasses over
your head, I wouldn't worry. We've had magnets for over 200 years now,
and so far nobody has ever had any brain problems caused by them.

....that we know of...

I read something about the possibility of birds being able to navigate over
water over long distances by somehow sensing the earth's magnetic field.

You will, of course, do what you think best -- but I just relined my tinfoil
hat.

Right,

Have any suggestion how alternating current in your socket , which has
form of wave
fits inside wire which is straight ?

Firm proof here that there is a such thing as stupid questions.
