Notes

“Prior to the 1930s, eyeglasses were only available without any kind of coating. Developments since then have allowed multiple coating types to be added to a single lens. This allows for clarity and lens longevity that were previously impossible, giving those who wear eyeglasses the freedom to purchase the best possible pair of eye wear for their needs.

The types of coatings with which eyeglasses can be treated vary depending on the type of material from which the lenses are made. The most common options include anti-reflective coating, scratch-resistant coating, anti-fog coating and ultraviolet (UV) treatments. Anti-reflective coatings eliminate glare and can improve the wearer's vision at night. Scratch-resistant coatings drastically reduce scratches to the lens over time, while anti-fog coatings prevent lenses from fogging up. UV treatments block all UV rays from passing through the lens.

As processes developed to allow multicoating, the available varieties of eyeglass lenses increased. Lenses today can be uncoated, fully coated (FC), multicoated (MC) or fully multicoated (FMC). Uncoated lenses involve no extra coating on the surface, while FC lenses come with one full coating. MC lenses have multiple types of coating and come in a variety of combinations. FMC lenses are basically MC lenses with all coating layers dispersed across the entire lens.”
