According to Google, "daily/monthly contact lenses" receives about 1% of searches in the more general "contact lenses" niche, which by itself isn't too big - so %1 is not alot.
Educating market is always a problem, experience shows that only big brands can do that successfully. Take me as an example, I don't wear lenses. However, i know many people who do. No one of them ever mentioned "daily contact lenses" so that niche was a complete surprise to me (i'm sure it will be surprise for them as well). Now, when I think of it, it makes sense. But I would never come to the idea that lenses can be 'daily' without your post.
The second problem you'll be facing is trust.
I wouldn't trust Chinese products when it comes to my eyes, neither will others. You'll need a brand behind these lenses.
