Soft lenses are usually disposable and can be thrown away after a short period of use. They are worn generally two to four weeks or daily, depending on the prescription. The risk of developing infection is significantly low with this type of lens. Soft lenses are made of a soft plastic and are very comfortable because they hold more water than rigid gas permeable lenses and many of the new materials provide ultraviolet (UV) protection. While most people choose soft lenses because of their benefits, there are also more fragile than hard lenses and can rip or tear while cleaning.
The latest revolutions in soft contact lens technology are Daily Disposables and New Silicone Extended Wear Disposables as they are only worn one time and then thrown out, being excellent for allergy sufferers. The Silicone Extended Wear Disposables are made with a new material and can be worn for up to 30 nights and days, providing the highest level of oxygen transmissibility. The new silicone material also allows the lens to avoid deposit buildup and reduce dry eye irritation.
Rigid gas permeable (RGP) lenses are more rigid, therefore more durable for an active user. It is made with silicone polymers, allowing oxygen to circulate to the cornea of the eye. They are also extremely durable and easy to take care of, another good quality being that deposits from tears and outside irritants are not as easily absorbed.
Extended wear contact lenses are available for overnight or continuous wear ranging from one to six nights or up to 30 days and are usually soft contact lenses. They are made of flexible plastics that allow oxygen to pass through to the cornea.
Plano, zero-powered or non-corrective lenses are not to correct vision, but intended to change the appearance of the eye. They can temporarily change a brown-eyed person’s eye color to blue, or make a person’s eyes look “weird” by portraying Halloween themes, cat eyes, USA flag and more.
Whether you wish to use only decorative lenses or need a corrective contact lens, it is recommended to ask for professional help, as your eye care doctor can help you decide what lens care solutions are best for you.
