Contact Lenses are designed to change with the wearer’s eye
Contact Lenses, also known as simple lenses, are thin plastic lenses usually placed directly on the cornea (the transparent covering of the eye). Contact lenses have been worn by more than 150 million individuals worldwide, and they are worn for medical or cosmetic reasons or to correct vision. Contact Lenses are made of a complex composition of plastic and/or gel, and they are shaped and designed to bend and curve to reflect light for an optimal contact lens user experience. These extraordinary lenses are made to provide optimal comfort, and most Contact Lenses come with an adjustable soft-contact-lens holder that allows users to wear the lenses in a variety of sizes and styles. Contact Lenses are designed to change with the wearer’s eye, allowing the individual to adjust the level of vision they need through the lens system.
Contact Lense users should follow the instructions provided by their optometrist. The instructions will specify how many contacts to purchase, when to switch them, what brand and type of lens, what type of cleaning and care to do, what to avoid, etc. The instructions will also specify which contact lenses are appropriate for each eye, and how to care for and maintain the lenses. It is important that patients follow the recommendations of their optometrist so that their vision remains safe and their eye care is successful.
the degree of softness needed to correct vision
There are two basic types of contact lenses – Soft and Rigid. The difference between the two is based on the degree of softness needed to correct vision correction. Soft contact lenses require a lower level of softness than rigid ones, but Rigid contact lenses require a higher level of softness to enhance vision correction. Some contact lenses are available in both forms.
The daily disposable contact lenses are the perfect solution for people who do not need continuous wear or long term wear, as they are used once and disposed of. These types of contact lenses are available in disposable, weekly, monthly, quarterly, six-month, and three-year designs. They can be easily worn throughout the day and can be stored in a drawer or a purse until needed. Once worn, these lenses can be discarded and replaced with a new pair without the hassle of ordering a new set from the optometrist or pharmacy.
daily basis need to consider extended-wear options
People who wear contact lenses on a daily basis need to consider extended-wear options. These lenses may be worn for an additional period of time, anywhere from several weeks to several months. However, extended-wear contact lenses should be worn only for the recommended amounts of time, depending upon the lens’s design. If contact lenses are worn beyond their recommended periods of wear, the eyes may become irritated and dry, which can cause discomfort and other issues.
Some people prefer gas permeable lenses, also called gas permeable (GP) lenses. Because they are designed to allow a small amount of air to flow through the lens, many people prefer to have this type of lens, even though they don’t require continuous daily wear. A small amount of oxygen flows past the gasket, carrying oxygen molecules through the lens to the eye. Because these types of lenses are designed to allow some breathing space, they do not irritate the eyes or cause other problems. This is unlike rigid contact lenses, which can overheat and become uncomfortable, if worn continuously.
