≥ If vision correction surgery is too expensive for you, you can wear glasses or contacts instead and be totally fine.

As someone who had lasik to correct a 9 dioptre astigmatism/myopia, I can tell you there is a world of difference between prosthetic correction and native correction. It's not just in terms of comfort. I can see better than I did with the perfect prescription glasses. I have a much wider viewing angle. I don't have to worry ever again with lens angle rotation.

For high corrections, glasses are anachronic, and should be considered the wrong treatment.
