Eye warming devices

[Mario]

I see alot of studies involving eye warming devices for dry eye treatment, but I don't see any of this eye warming devices being sold to general public. The only eye warming device I know is EyeFeel, but it is a little bit expensive to me.
Check this patent for an eye warming device (it's not disposable):

Mario, I only gave this a quick glance. I noticed there were no pictures of this elaborate contraption. Unless I missed the pics, and that's possible. If someone wants to read and decipher the jargon, I'd take another look at it. Is this actually a product, or has a patent merely been applied for, or granted? I can't read long articles.
