Hi All, Wanted to tell you about a new product I just learned of from my ocularist, John Imm. Nope, not a phone or texting or anything technology. <Smile> It's called Boston Conditioning Solution and is for rigid & gas permeable contact lenses. However, it works great for artificial eyes. It greatly reduces the protein build up, allowing the natural tears produced by your eye to remain on the prosthetic. This in turn allows for better lubrication and natural cleaning. John, who is one of the best prosthetic artists I've ever had the good fortune to see, cautions to be sure that the Boston Conditioning solution you purchase says for rigid or hard contacts. Hope this is of help to some. Still can't tweet though! Haha! Take care, Sila
