Thanks. I’ve wondered about that. ...getting my first prescription bifocals soon after relying on cheap reading glasses for too long.
I got LASIK six years ago. No regrets, whatsoever.
I think it is safe. It was new in the early eighties. Read about its early trials. Opthalmogist cut on corneas every day. They perform cataract surgery by implanting new plastic lenses. They replace corneas from doners to those sightless. My opinion, the cutting of the cornea to correct astigmatism has been shown to be safe.
“Thanks. I’ve wondered about that”
One of the dirty little secrets of LASIK is that it doesn’t really help presbyopia. All it does is change when you need classes. If you happen to be like me and are near-sighted, then you wouldn’t need glasses for distance usage, but would have to use them for close work, which I can do fine now without glasses at all.
To overcome this, they try to convince you to surgically set one eye with a close focal length and one eye with a far focal length, sort of like having one eye set to macro vision and one set to telephoto vision. I simulated this with contacts and felt I had sub par vision all the time, so was smart enough to not go through with the surgery.
My wife and I both had LASIK in ‘03 doing I’m still 20/15, 20/20. It’s better then 20/2600 and wearing coke bottle glasses.
I know that anything with the word "progressive" in it is suspect around here, but they have some advantages over bifocals, along with some disadvantages.
Basically the prescription changes from the bottom of the lens toward the top. The top of the lens is set for long distance vision, and the bottom for close-up. There is always some point along the lens where you can see a specific distance with extreme clarity and focus.
The only downside is that if you are looking at a particular point in space for a long time (ex. a computer screen or TV) then you tend to keep your neck in a very specific spot and it can get stiff and sore.
I have progressives which I use when moving about, driving, etc. I have another prescription which is specifically set for the distance between my eyes and my computer screen. That way I can move my neck around while working or Freeping. My computer glasses are the cheapest I could get with the cheapest frames, and no coatings. I didn't want to spring for two sets of fashionista specs.
Best of luck with your new glasses!
