Any opthalmologists or other occular medical experts out there? For decades, I've been making my own (usually elaborate) Hallowe'en outfits, including latex appliances. My avatar is one example of that. One thing that I've never been able to justify buying is costume contact lenses such as cat's eyes, red demon eyes and the like. Rather than latex in some cases, I've made small prostheses from pure gelatine mixed with about 6-10 times less water than is used for dessert Jell-o (depending upon desired consistency). It's very similar to latex or even harder rubber when set. It suddenly occurred to me that I could make my own contacts from that, using distilled water. That is no problem whatsoever to do, but I have no idea of whether or not it would be safe to wear them. Discomfort is not an issue, but possible damage certainly is. Do any of you (EXPERTS ONLY, PLEASE) have some thoughts about this? Thanks in advance.
