lenses

It may be worth mentioning that the Halo-ing is also present with contact lenses, at least for large lens strengths.

But generic code is just always going to be cray-cray (See: Haskell lenses, C++ Boost, Scala collections).

You should never put water on contact lenses as water is a strong vector of bacterial infection.

Both of these flaws relate to how toric lenses work: they're weighted to maintain their orientation.

They don't need weighting for correct orientation, which eliminates the aforementioned limitations of soft lenses.

This required me to get toric lenses and they were much, much more expensive.

If you need contact lenses in the future, they'll have to be rigid (eg.

By engaging directly with consumers, we’re able to offer ultra-high-quality, vintage-inspired frames for $95 including prescription lenses and shipping.

As such, when I'm in for an eye exam no one recommends soft lenses for me anymore.

It's normal to need a Lasik redo or lenses again after 10-20 years.

If I wear corrective lenses my eye tries to merge two images that aren't the same size.

The visual acuity for my correction is in all ways superior to soft lenses I've tried.

Astigmatism with soft contacts means toric lenses, which have a few annoying "quirks".

It was only looking at people using daily lenses (the variety that I use) so things might be worse for monthly or "permanent" lenses depending on what you clean them with.

A quick Google search revealed the paper "Reactive Lenses" [1], which seems relevant.
