Lentils: Best ways to cook them?

Hey everyone... so, I’ve been rocking glasses for about four years now—my prescription is -2.0 in the left eye and -4.5 in the right. Since my next eye exam at the clinic is coming up pretty soon, I’m thinking it might be time to give contact lenses a shot... I was wondering if anyone could give me an idea of what the costs look like with my specific prescription, and also how long a pair typically lasts before you need to swap them out... thanks much

Nah, that's only for the semi-firm ones. If they're soft, you can just pull them right out—either by gently scraping them away from the rim or just giving them a little pinch between two fingers. It's pretty straightforward, really.👍

It really depends on whether you go with soft lenses or something a bit firmer. With soft lenses, you've got options ranging from daily disposables to bi-weekly, monthly, quarterly, or even yearly supplies. Prices can vary quite a bit—you're looking at anywhere from $200 to $167 for a three-month supply. Just so you know, the cost isn't actually tied to your specific prescription strength. Honestly, your best bet would be to browse some prices and deals online (check out Walgreens for example) just to get a feel for what's out there. But look, at the end of the day, just head to the optometrist first. Let them do the exam and they'll tell you exactly what will work for your eyes.👍

Hey everyone!
I’ve been dealing with corneal keratoconus for quite a while now, so I've pretty much lived in hard or RGP lenses for years.
I was wondering if it would be okay to switch over to soft contact lenses just temporarily during sports or physical activities?
Mainly because they don't pop out as easily and they're definitely easier on the wallet. I'm just not sure if wearing soft lenses would have any negative impact on my keratoconus...
🤷
Thanks

From what I understand, soft contact lenses aren't really an option for managing keratoconus, since you essentially need a lens that can provide enough structural pressure to reshape the cornea; this ensures the image projects more clearly onto the retina without causing any double vision or blurring.
I haven't actually heard of anyone living with keratoconus who uses soft lenses... 🤷

I have one simple question: what exactly are these so-called silicones used for breast implants and soft contact lenses made of?
I get that it’s some kind of silicone, but does anyone actually have a specific answer?
I need a material with those exact properties...
Thanks.

I don't know about your specific situation, but honestly, finding a concrete answer to that question is going to be tough.
Regarding contact lenses, you won't find an exact chemical breakdown anywhere.
With silicone hydrogel lenses, all you'll ever see is that they contain silicone fibers and water; the specific type of silicone remains a mystery.
The best you'll get are labels like balafilcon A or polymacon,which doesn't actually tell you much of anything.
I've tried to figure out the precise composition of my own lenses before, and I came up empty-handed.

As for implants, it depends on the procedure—they use various types of silicone and different additives.
Again, pinpointing the exact chemical makeup is nearly impossible.

Unless someone here is a specialist in this field who can give you a technical answer, you're out of luck.

If you are truly hunting for that specific material, maybe try looking into industrial suppliers, though I haven't the slightest clue where you'd even start.

Thanks for the reply. People suggested I ask at a lens retailer, maybe they'd have more specifics... I'm actually in manufacturing and I'm looking for an extremely soft material, so I'm trying to track down some real data!
