Why is it absurd?

I'm assuming your total compensation is the same either way. So it's not that you're not being compensated for staring at computer screens all days, it's just a question of whether your being compensated by being given dollars or being compensated by your eye doctor and glasses manufacturer being given dollars.

Upon rereading your post, your point makes more sense. But don't you at least get discounts on the exams and eyewear? I would assume there's some justification for why vision insurance exists beyond the serious conditions you mention, and thus be an additional benefit from employers of workers who experience ocular wear and tear all day.

You get fake discounts off egregiously inflated eye exam/eyewear prices

You can easily buy prescription glasses online for less than $20 a pair, and you can get an eye exam done for $50-$100

If you use your vision insurance to buy glasses in person, though, good luck getting them for less than $150. The price of the glasses magically inflates to whatever your insurance will cover.

If my vision insurance weren't bundled with my employment as a "free" benefit I'd definitely just use $80 out of my HSA to pay for an eye exam and then buy a sack of glasses online
