If they’re thinking about discontinuing them, I don't think it's because there's anything wrong with the product itself. It's more likely because everyone is switching to silicone hydrogel lenses now. Those allow for much higher oxygen permeability, which makes them significantly healthier for your eyes. I'm not sure how familiar you are with this, but wearing low-oxygen soft lenses long-term—especially from sunrise to sunset—can lead to complications due to oxygen deprivation.
The cornea doesn't have blood vessels; it gets its oxygen directly from the air. Since lenses act as a barrier, the cornea starts growing blood vessels into itself just to try and get enough oxygen.
This is called corneal neovascularization, and it damages your vision by reducing the transparency of the cornea.
Just for context, Optima lenses have a Dk (Oxygen Permeability) of 8.5, whereas silicone hydrogel lenses have a Dk of over 100.
That's exactly why I switched from Optima to silicone hydrogels (Air Optix).
Specifically, those have a Dk of 110.
So, it isn't just some attempt to "upsell" you on more expensive lenses.
I’ve been wearing soft lenses for 15 years, and I've actually started seeing early signs of neovascularization myself. It's nothing serious; it clears up once the cornea starts getting sufficient oxygen.
Since it only showed up after 15 years, it suggests that oxygen deprivation isn't an immediate crisis for everyone.
However, it's highly individual and depends entirely on how your specific eyes react.
The bottom line is that the cornea needs oxygen, so your ophthalmologist definitely wasn't giving you bad advice.
Now, whether it's absolutely mandatory is a bit debatable. But it is undeniably better for your eye health.
Uh, now you've got me worried too. I've been wearing soft contact lenses for 15 years.
Every time I place a new order, I have to switch manufacturers because the ones I used previously aren't available anymore.
I've tried Johnson & Johnson, CIBA Vision, Bausch & Lomb, with prescriptions of +2.50 and +2.75, and various water contents—most recently 74% because my eyes get incredibly dry.
Now I'm being offered Bausch & Lomb Optima again, claiming they're the best, with 38.6% moisture.
They come in packs of four, which lasts three months, so that covers a year.
So two packs would be $187.
They also offered me silicone versions, but I didn't know enough about them, so I passed.
I actually ordered them, and they should arrive tomorrow, but what exactly is oxygen permeability, and where is it noted on the boxes? What labels should I look for?
The big issue is that the salespeople often don't have a clue what they're actually selling, so how are you supposed to decide what to buy? That's just my experience.
