If you suffer from astigmatism or presbyopia and have discomfort during wear of contact lenses due to dryness, the Proclear Multifocal Toric contact lens might just be the right thing for you. The Proclear Multifocal Toric contact lens is a type of toric lens that helps correct astigmatism and presbyopia, which is caused by the aging of the eyes which makes reading small or seeing close objects difficult. It is the only one available that requires monthly replacement carrying such function.
In order to address both astigmatism and presbyopia, the Proclear Multifocal Toric contact lens is designed using Balanced Progressive Technology TM, and is combined with a material called PC Technology TM, which allows a person to have good vision at any distance, and at the same time, remain comfortable and moist throughout the day.
How the lens functions is very simple indeed. Basically, the lens allows light to be focused to the back of the eye, regardless of objects of near or far distances. As a result, the image is clear. In order for the lens to allow light to focus properly and comfortably, the two different systems – Balanced Progressive Technology TM and PC Technology TM – complements one another to make that possible. The PC Technology TM is a material that contains the phosphorylcholine (PC) molecules which are naturally found in the membranes of human cells. These molecules have the ability to attract and surround itself with water, making the lens able to stay moist and comfortable. On the other hand, the Balanced Progressive Technology TM is a process that combines spherical and aspheric optics as there are unique zones of the lens that holds different sizes.
As it is able to provide comfort in wear, the FDA has claimed that contact lenses that have symptoms of discomfort during wear of contact lenses due to dryness would be able to feel much comfortable with these.
