The Different Varieties Of Biofinity Contact Lenses
Contact lens technology has developed considerably over the past decade. There are many different brands and types of lenses. However, until recently, options for individuals who had particularly sensitive eyes were limited. Fortunately, Biofinity Contact Lenses were introduced as a solution to this problem. These contact lenses are constructed of a soft silicon material that permits a greater flow of oxygen to the eye. This, in turn, keeps the blood supply flowing to the many blood vessels that are located in the eye and helps keep it healthy. Unlike rigid gas-permeable lenses, these lenses require less time for adaptation and do not slip off the center of the eye. Because they fit snugly and well, less debris gets under them and they feel comfortable and natural.
The special silicone hydrogel used in these lenses is ideal for people who suffer from the irritation that can be caused by having dry eyes as well. This type of silicon is naturally wet and does not require any type of extra wetting solution or surface treatment. The water is retained inside of the lens while it is being worn, creating minimum dehydration, while keeping the eyes healthy looking, clear and comfortable.
Astigmatism is caused when someone has an eye defect caused by an irregularly spherical curvature. This prevents the light rays from meeting at a common focus. Biofinity has also created contact lenses for people who have this condition. These Toric Contact Lenses work by correcting the eyes' refractive errors. These lens are created with curvatures that are at different angles and with special engineering that prevents them from rotating while on the eye. This is another example of contact lenses that are comfortable and natural feeling.
A third type of lens that is manufactured using the same silicone hydrogel technology, is the multifocal lens. This lens helps wearers experience improved vision whether they are nearsighted, have presbyopia or have vision that is anywhere in between those two parameters. Presbyopia is the condition that many people incur as they age. As people age, their natural lenses become thicker and become less flexible. When this happens, the muscles surrounding the lens become weaker, and it becomes more difficult to see. Multifocal contact lenses work by focusing light from far, intermediate and near distances to the rear part of the eye. This creates an image that is as clear as possible.
Through the years, contact lenses have helped to improve the lives of millions of people throughout the world. As contact lens technology continues to improve, there is an increased likelihood of even greater advances in vision enhancement. Whether one chooses contact lenses for cosmetic purposes, for corrective vision or simply because he or she does not care to wear eyeglasses, there are many exciting possibilities available with more being developed each day. To find out which contact lens options are best suited for a particular individual, he or she should consult with an eye care professional that can explain the various possibilities and offer guidance with the selection process.
