> The ultrasonic cleaner and distilled water are more expensive and have greater ongoing costs, although it looks like £13 of distilled water will last for about 3 years Weird complaint, because distilled water is $1 CAD for 4 litres here at any supermarket.

Paying more can get you thinner lenses? This is of interest to me as I do have coke bottle-thick glasses.
Mine vary from "too thick for almost any frames" to "looks like a normal pair of glasses until you look through them" depending on cost. Mine are somewhere around 1/3rd as thick on the edge as cheaper glass. Look for "high (refractive) index" lenses. It bends light further, so you need less material / less angular difference to get the same effect.

Even with Zenni my eyeglasses cost over $100. At Costco they cost $300, and at most other places they cost $600. I used to always go with Costco, but last year I tried Zenni. The frames are definitely flimsier than any others I've had, which I've heard is generally the case for their wire-frame options—I'm sure their heavy plastic frames are more sturdy, but that's not my style. But the lenses seem as good as usual.…
Be careful with using ultrasonic cleaners or using otherwise strong solutions because of the risk of taking off polarized/anti-glare lens coating, if you happened to have gotten it (you probably should have :)). Working in a lab that had ultrasonic cleaners, I used to do this and it happened with me after a few washes. It is indeed a bit of a pain to clean it (I'm lazy and just don't... unless it gets really, really…
I've never done anything other than breathe on them and polish with the bottom of my shirt. What am I missing?
Grease is not entirely caught by cloth; the stickier/large the grease patch, the more it will spread over the lens, making it time consuming to clean.
The best method I’ve found so far: 1. Get your glasses wet with warm water. 2. Apply dish soap to both lenses. 3. Gently rub the soapy water over the lenses. For some stubborn things (like sunscreen) in the edges I sometimes gently use a Q-tip. 4. Rinse under warm water. Gently rub with your fingers to agitate the soapy water and help rinse it off. 5. (This is the important step) Adjust the faucet’s flow to a low lam…
This final step is also how soldiers get those perfect mirror finishes on their boots and belts!
If you think you can withstand and are a candidate for lasik, I highly recommend it. Like any medical procedure, weigh options, cost, risk.

A good chunk of people require glasses that need to be custom-made. Once you also add amenities like photochromic lenses, it quickly adds up.

1) The glasses have to accurately hold my the lens at a specific location and orientation relative to my eyes in order that they actually work.
Off by a little bit and it's world of splitting headaches and crazy distortion
Achieving that positioning, while dealing with my wonky ears, size of head, eye locations etc - requires knowledge beyond current web systems before ordering and - unless completely bespoke fabrication of frames as well - some form of final fitting post delivery.
- The prescription is sufficiently rare that the lens are not mass produced and instead have to be custom ground and cut to fit the frames before the glasses can be assembled.

Depending on what your lenses are made of, and if you have fragile coatings on them, and if you live around or work with fine abrasives, this works fine. I miss actual glass, uncoated lenses.
