history: I have really great eyesight, I don't need glasses. What about you?
knowledge: These anomalies can mostly be corrected by optical means (such as eyeglasses, contact lenses, laser surgery, etc.).
response: I have no such issues but did you know there are other methods to correct them too like contact lenses?

Oh yeah I know but I think glasses is like the most common one, my guess at least. How well are contact lenses doing anyway money wise?
knowledge: Multiple analysts estimated that the global market for contact lenses would reach $11.7 billion by 2015. , the average age of contact lens wearers globally was 31 years old, and two-thirds of wearers were female.
response: Well, a bunch of analysts approximate that the market for them hits over 11 billion dollars in 2015.

Whoa that is a lot. But aren't they just daily stuff? Feels sort of like daily use would change your eyes over time right?
knowledge: Long-term contact lens use can lead to alterations in corneal thickness, stromal thickness, curvature, corneal sensitivity, cell density, and epithelial oxygen uptake, etc.
response: Yeah, they can lead to changes in cornea thickness and other various changes.

I didn't know that. Does surgery help at all?
knowledge: Decreased corneal sensitivity, vision loss, and photophobia have also been observed in patients who have worn contact lenses for an extended period of time.
response: I don't know but long term wearing has lead to also things like vision loss as well.
