Have you ever worn progressive lens eyeglasses?


I've heard people say their favorite form of eyewear is progressive lenses -- but I'm baffled as to how these could work for sustained computer usage. Usually I'm using my laptop, on my lap, and my new progressive lenses seem to never show clear letters except at a certain angle, requiring an uncomfortable tilt of the head.

The conventional wisdom is you get used to them after two weeks and then can't imagine wearing anything. Any HN readers have their own experiences they'd like to share?

Yes, the screen is a plane at almost constant distance from the seated eyes = a single constant correction for the correct range is best. So carry the correct single range reading glasses for when you use a screen. For the real world where far away is typically glanced up to view and the flat desktop ranges further fits the progessive lens. This is what I have. Glasses of real glass that I use for the screen only and keep them there, both my eyes differ, so Walmart plastic readers do not work (I suppose I could buy two pairs and swap the lenses using a blow dryer to soften the frame to swap the lenses.) I prefer true glass lanses = they do not scratch at all in daily uses - the plastic lenses soon accululate all mannr of tiny scratches which I hate. For real world use I have progressive lenses and you soon adapt to the slight head motion to move the perfect focus zone onto your eye (fovea range fitting) I have seen some glasses sold online a few years ago with a hydraulic squeeze bulb that moves the lenses apart/together as you adjust the squeeze.A google just now could not find them = failed idea?? A tesla type radar that autofocussed would work? Many cameras have autofocus and a light weight focus adjuster that moved the lenses should be makeable? (there might be one sold now since they have autofucus on cell phones = why not eyeglasses??) The Chinese sliding lenses made of molded plastic to achieve a similar effect, but fail badly in execution. The lenses are terrible ripply quality. I bought a pair from Aliexpress for $4. All plastic = not worth buying. The same thing is being spammed at $50 or more in the USA, same crap, you will toss the same day you get them.. That said, the idea is valid and of they made it with glass lenses they could work for many uses. I expect they are out there somewhere?

I got upsold on progressive lenses at my last eye exam. It was an expensive mistake. They literally make me dizzy and sick when I turn my head, which happens constantly with my multiple monitor set up. I ordered a new pair of fixed plane computer vision glasses, but I think the manufacturer gave me reading glasses. From what I can tell, the focal plane seems to be nearer than my last pair, so I find myself leaning into the screens to find the optimal focus. Turns out that computer vision lenses are not exactly the same as reading glasses, so I have now paid for two pairs of glasses this year that are not suitable replacements for my last prescription. As a result, I now get to suffer until I can afford to try again next year, and my trust in the eye care industry has reached a new low.

I talked about this with my optometrist and optician and they recommended I get a pair of reading glasses and a pair of distance glasses.

Any kind of bifocal is a compromise and might be convenient for some people, but if you are trying to maximize your sensory acuity they aren't a good choice.

I had them and I think I was ok with them on my 13" laptop screen, but definitely not when I used a larger external monitor. I was constantly having to turn my head to get text into focus which was frustrating and distracting.

I've heard that there's a large variety of progressive lens types and I suppose that might explain why some people are ok with them and others aren't, though I'm not going to try again for a computer distance prescription.

I now have single prescription lenses for working at my computer and bifocals for everything else, though I'd consider replacing my bifocals with progressives at some point.

I got my single prescription lenses at Warby Parker for $100 and I'm really happy with them.
