Dear Sir, Now I am very happy to introduce brand new cosmetic contact lenses. Holes and grooves...I know it 's not easy to understand that. But.... it has realized now. Cosmetic lenses....it's based on medical devices. not olny for cosmetic. Holes and grooves inside the lens give patients who wants cosmetics use enough medical environment as a lens. It could be a " Binggo" on your business. Feel free to contact me at anytime you want. I can help you. Thank you
