Why amblyopia (lazy eye) cannot be surgically or anyhow treated at adulthood? I know that if treated properly at childhood that eye can function normally, but why is it hard to develop it later?

When I was 8 years old my right eye was injured and the lens had to be surgically removed. As this was 1990 we didn’t have the tech to implant anything so I was fitted with a corrective contact lens that gave me about 100/20 vision. Enough to easily identify an object and maintain stereoscopic sight but not enough that I felt unhindered. Being young I’m sure you can imagine how well wearing a contact that had to be removed nightly went. I hated it. My middle school I was barely wearing it. Eventually that eye began to drift. By high school it was nearly set but strenuous activity would somehow align it. Vision in that eye is SEVERELY limited. It’s pretty much good for detecting light and very large objects. It’s also much more sensitive to light period and the strangest side effect is that I can now see “black” lights as very bright purple objects. Anyway… So now I’m in my late 30’s not really self-conscious about it but I’ve asked my eye doc about it when being measured for glasses to treat my near-sighted left eye. He said there is surgery available to align it and there are now also implants I can get that would allow some ability to focus on near and far objects. He never once mentioned age being a thing for the alignment surgery.
