My hovercraft is full of eels.
My left foot does not have eels or salmon

Well I thought this post could have some useful discussion,
Most people in the 70 years old develop cataracts.
I se a lot of bs.
Some lenses are made from Acrylics, some modified silicone, some are soft, when cataracts lense is inserted what are the material is in the replaced lense .
There are 41 million American using contact lenses
The contact lenses is a business 7.2 billion.
This is supposed to be a chemical forum
The problem was that your question did not make sense.
Read your original post
It does not make sense
Your post above also is nonsense
Millions develop cataracts which are a natural occuring clouding of the lens of the eye and a quick Google shows
What are Cataracts?
A cataract is defined as the clouding of the eye’s natural lens, which is located behind the iris and the pupil. Cataracts are a natural eye condition and are the most common cause of vision loss in people aged over 40. In fact, cataracts are the leading cause of blindness worldwide. Thankfully, they can be easily treated with corrective lenses or cataract surgery

Contact lenses are glasses
Lot smaller
Sit on the surface of the eye not perched on the nose
Don't have a frame
Having personally undergone removal of cataracts from each eye and having intraocular lens inserted as replacements I definitely noticed a difference
Mostly brighter more vivid sharper colours and allover clarity of vision
Still require glasses although some may not
Aside from confusion about cataracts and contact lenses I find it odd that a Government would allow a 7.2 billion dollar business to operate which turns people blind???

Thank you for informing me . I had cataracts and my lenses were replaced. I am familiar with That.
The point is what chemical materials are used in the replacement and what chemical material are used in contact lenses.
That can not be more clear of a question.
I would not expect from you since you are a retired nurse and I am a little familiar in the limitation of your profession in chemicals, my 2 wives were nurses.

Correct
Then step carefully and get out of the cattle field.
Look at this Wiki entry Introcular lens
OK.
OK.
This is the chemistry section.
Is there some sort of point to your post?
That is a clear question - your earlier attempts were not clear at all.
I already gave you a link to what cataract replacement lenses are made of and here is what contact lenses are made of: Contact Lense Material.
Yes to discus chemistry of the material used in lenses and in material used in cataract surgery.
Great ! so we have something in common > English language was not my priority nor is now. Material and science behind it is of more interest for me.My first job was as a analytical chemist in London
