I had a tear, a retinal detatch, emergency 10PM surgery with
vitrectomy, laser retina welding, secondary cataract lasered twice.

They look the same to me.

It's time to do the other one.

You may not be able to see it yourself, or at least yet, but they stand
out like "noise" in dark scenes of a DVD. Once you see it, you can never
not notice it again,

What is the spectral characteristic of the sensitivity of an ultraviolet LED used as a photodiode?
My 280nm UV LED OSRAM picks up light from a low pressure mercury lamp with a wavelength shorter than 300nm.

I make amps for photodiodes that work at 193 and 13 nm. Windowless of
course.

Fortunately there's no sun where these go.

We also process a fast (<1 ns) IR detector, a photo-electro-magnetic
thing. They cost around $1K each.

My right eye, with the plastic lens, doesn't look flat. In fact it
looks curvier than the other one.

I'm thinking that most people elect to have 20/20 distance vision, so
get flat lenses. I decided to have one eye focus at about 24" and one
at about 10, so I can use a computer or read a book without glasses.
So I'll have two fairly thick lenses.

I also have had cataract surgery, now on both eyes, with focus
distance intentionally set to something like 12 inches, for easy close
work. But each eye can see the reflection off the other eye's lens if
the light is just right. I would assume that others can see the lens
reflections as well.

It's an odd reflection, nearly as intense as a cubic reflector, but more
angle sensitive. There has to be a flat surface in whatever those inserted
devices are.

I have good vision for reading and computer work. It's amazing how
both eyes work together when they have different focal distances.

"Red eye" reflection is common with natural lenses.
