The range of lenses available have never been better. Understand the pros and cons typical types of lenses and also the basic rules for the prevention of eye problems.
Soft contact lenses
Contact lenses that are soft among the most commonly prescribed contact lenses. They can help solve a wide range of problems with vision that include:
Vision blurred (astigmatism)
Deterioration of close-up vision as we age (presbyopia)
Soft contact lenses are comfortable and are more comfortable to use than gas permeable rigid lenses. There are a variety of soft lenses comprising:
The lenses are designed for wear every day. One-day lenses are intended for use during one day. They are able to be taken off and then disposed of in the evening. Additionally, you can get disposable lenses which can be used for up to two weeks along with quarterly disposable lenses. They are generally cleaned each night, to keep them clean and cleanse them.
Overnight (extended) wear lenses. Some soft contact lenses can be used for as long as 30 days in a row, even in the night. This type of lenses can lead to complications like the accumulation of debris under the lens cornea, cornea problems, or cornea infections.
Rigid gas permeable contact lenses
Rigid gas-permeable lenses provide clarity and sharp vision for individuals with vision impairments of all kinds. Contact lenses may prove beneficial to you if your attempted soft contact lenses but were not satisfied with the results or if you’re suffering from “dry eyes.”
The rigid gas permeable lenses are more durable in comparison to contact lenses that are soft. They’re also breathable, allowing more oxygen to the cornea. Contact lenses should be taken off for cleaning and cleaning at night. However, some can wear for as long as a one week or up to 30 days.
The lenses may need adjustment your gas-permeable, rigid contacts for a duration. If your prescription does not change, and you maintain your contact lenses, then you’ll be able to use the same pair from two to three years.
Specialized contact lenses
Depending on your vision needs, you might consider specialized contact lenseslike:
Hybrid contact lenses. They consist of a gas-permeable center as well as a soft outer. They can be used to correct farsightedness (nearsightedness), astigmatism, and other age-related changes in close vision. They also have the ability to correct the irregular curvature of the cornea (keratoconus) Additionally, they may be more comfortable to wear in comparison to conventional gas permeable lens.
Contact lenses with multifocal lens. They’re constructed from different materials and are used to correct presbyopia and also as to correct nearsightedness.
Tinted contact lenses. Tinting contact lenses for therapeutic and cosmetic uses is possible. Tinting could enhance the color perception and help compensate for colorblindness like.
Contact lenses to treat Scleral. The gas-permeable rigid, opaque lenses are often larger than others and extend to the outer white layer of your eyeball (sclera). If you have a distorted or uneven cornea, these lenses could correct your vision.
Orthokeratology. These special rigid gas-permeable lenses are worn while you sleep to change the shape of the cornea. This creates clear vision while you’re awake.
Contact lens coatings. This process makes the exterior of the lens slippery , and less prone to bacteria adhering to it. This coating is able to be applied to soft and rigid gas permeable lenses.
Finding the perfect fit
When you first get contact lenses visit your doctor to have a comprehensive eye examination and fitting. It is possible that you will require a follow-up check after one week, 6 months and one month after which you will need to visit once a year , or every two years.
