I have astigmatism (-3.75 diopters of it in one eye), and there has never been any extra charge for making my lenses. Where are you getting this idea that astigmatism-correcting lenses are quite a bit more expensive?

I’ve seen some glasses manufacturers charge me more for astigmatic lenses specifically. Never to the magnitude the other person mentioned but also not at the same cost. It was part of the cost breakdown on the receipt, but likely they’re just fleecing people. I didn’t end up buying from them.

But in general, it’s been the same cost as non-astigmatic lenses.

What I meant to say is, lenses “may” be more but I accidentally dropped the “may ”. Too late to edit now

For that size of astigmatism I would think there was an extra price you don't get the price of a lens broken down like that (bi focals and the blue filter will show up as extras) So how do you know there is no extra.

I just had to pay more as my prescription on astigmatism went from 2 to 2.5

I go to https://www.goggles4u.co.uk/

There are frames advertised, with prices, before they have any idea what my prescription is. I add to cart, and give my prescription. The price is the same. So, they can't be adding extra for my astigmatism.

You likely had to pay more to get the thinner "high index" lenses. Otherwise lenses get pretty thick at that power, but they don't cost much more as long as you're willing to live with that thickness.

Ah - they all look thin to me.

I had my cataracts replaced and before that astigmatism was the least of the issues -20 diapotre for short sight are quite thick
