The only thing I’ve learned about cataracts is that they reduce the amount of light entering the eyes and they’re slightly yellow in color, so I wonder what effect that has on processing images in post.

Ah yes, cataracts will discolor your vision. I had mine fixed very early in the process as I didn't want several years of prints coming out too blue.

Poorly stated but perhaps you can get the feeling that I'm talking about compensating errors.[/quote]

Couldn't agree more. Makes no sense. adding more yellow to yellow makes more yellow, not less.

Yup. Well, I am enjoying the improvement in color and clarity, for sure.

I was really happy at the idea that I wouldn’t need glasses except for reading. While that’s true, now I have to put glasses on and off, or just get bifocal glasses that are clear on the top part and with a diopter on the bottom for reading, and just wear glasses again. Oh well, I can see, and that’s what counts.

I made the choice to go with glasses all the time. I have a very mild correction in the top, to about 20-10 or 15, but I don't absolutely need it. But what I do need is reading glasses. An I understand that I will lose about two pairs a week. So if they are always on my nose, I'm ok.

And anyway, I discovered through the two weeks after I go my surgery that the reading glasses sold in drugstores are crap. Never found a pair that was anything but one of those $40 135 teles that were sold under a number of different names in the late sixties.

I’ve been experimenting with some cheap glasses. I found a pair at Walmart, but like you said, junk. Then I found some clear and dark tinted safety glasses that are also bifocals, at a hardware store. They work well for driving, but not so much otherwise. I go in next Thursday to get my final check and determine my exact prescription. Since my insurance covers all of this, I’ll pick a set of new frames and have some custom lenses done, and just continue wearing glasses. It’s nice to know I don’t need glasses for far vision, but I might as well just wear proper glasses.

"Spec" I am in same situation. I go on Jan. 7 for exam for glasses for closeup. Thankful for great distance vision but this taking on and off of glasses gets old. I would still do surgery again as vision is so clean and sharp.

It should not have made a difference, but I guess it does.. your brain adjusts color so that you see what your brain thinks is normal.. remember putting on a yellow ski mask, the world turns yellow fer a few seconds, the back to normal, when you take the ski mask off, the world turns blue for a bit......your brain at work.. I had both eyes done years ago, greatest thing since sliced bread..... Ed

I imagine the effect on post processing would be pretty dramatic. A neighbor who recently had cataract surgery said that afterward she saw colors in a whole new way: accurate and brilliant. If your color shift continues, you may be able to adjust your monitor to match your color perception, so "what you see is what you get." As the problem improves you can tweak the monitor settings to match.

Things are looking pretty good right now. I haven’t done any photo editing yet. For the most part, what I see is that whites are so much whiter and colors are just clearer and “pop” more.

All this interests me. Soon I will have cataract surgery. I'm wondering, in particular, how surgery and/or vision correction has affected your ability to use your camera and viewfinder.

Right now I take off my glasses to look at the settings on my camera. Yet I use my glasses (distant section of bifocals) when composing through the viewfinder. (DSLR) I am especially interested in anyone's experience if they chose to have cataract surgery done so that CLOSE VISION does not require glasses.
(I will ask my opthamologist about the diopter adjustment on my viewfinder.)

I chose the "near" correction so that close vision doesn't require glasses - both eyes were done. As you mentioned, just change the diopter adjustment on your camera to compensate for distance vision.

yssirk123 Thank you for sharing your experience! I've found few people who have opted for near correction.

I no longer require a distance correction, just near correction for reading. I’m really appreciating that now. So my new glasses are the “progressive” lenses, no line bifocals, with a near correction, but no distance correction. I chose to just wear glasses because it’s just plain inconvenient to deal with reading glasses. I guess I’m just used to wearing glasses after over 30 years of wearing them.

As for the viewfinder in the camera, I just adjusted the diopter to match my eye. Unless your vision is bad enough that there isn’t enough range with the diopter adjust, you shouldn’t need to consult your eye doctor. At least that was my experience. Just a quick turn of the little knob and all is good.

I'm happy for having no glasses for distance correction, although I still wear bifocals. I can get up i the morning and find my way to the bathroom without hunting for glasses, and it's no problem for having glasses for close work. AS far as the VF, adjusting the diopter is no big deal. Do it once and you're done.

Thank you all for your feedback! I've worn glasses for 55+ years and eventually progressed to progressive lenses. (No pun intended.) I now have bifocals, which the opthamologist recommended, but I hate them! Ever since I got my first DSLR in 2006 I have maxed out the diopter adjustment.
