Our lenses are made of PC Hydrogel. PC Hydrogel means a product containing this substance in a lens material or coated with this substance.
PC is short for Phosphorylcholine, a biocompatible material commonly used in medical implants and prosthetics. It is safe and non-rejective material in the human body, as it is used in medical devices for human implantation, with the same molecular structure as protein cells in the human body. Also, because they tend to stay hydrated than other materials, lenses contain this substance can stay moist for longer.All lenses made by COLORCL is made of PC Hydrogel. But, there's a slight difference. As mentioned above, PC Hydrogel means a product containing PC in a lens material or coated with PC. COLORCL is using both types of materials.
Siesta collections that are designed for up to six months of use are PC Hydrogel based on Polymacon. The lenses made by mixing the polymacon with the PC and coating it with the PC.
Lenses that are designed for a week or a month use are upgraded PC Hydrogel based on Polymacon. The amount of contents of PC is higher than the lenses for up to six months of use. Relatively, lenses can stay moisturized longer, but they are slightly less durable and can be difficult to use for longer periods of time than a week or a month.
Blanc Rosé, Herrys Blossom and Lucid Dream collections are the latter cases. These products are also Silicone Hydrogel and PC Hydrogel because it contains Silicone Hydrogel for lens material and coated with PC. It also called Si-PC Hydrogel. (Label can be marked silicone hydrogel or PC Hydrogel.)
