There are various types of contact lenses that can help improve vision depending on individual needs and preferences. These lenses can fix common vision problems as well as specific eye conditions, providing a convenient and efficient alternative to regular glasses.
Let’s take a closer look at some popular contact lens types used for vision correction:
- Daily wear lenses refer to contact lenses that are worn throughout the day and then taken out for cleaning and disinfecting before going to bed. These types of lenses can come in different choices such as soft lenses, toric lenses designed for astigmatism, and multifocal lenses for presbyopia. These lenses offer convenience and comfort for everyday use.
- Extended wear lenses are specifically created for long-term use, typically lasting up to 30 days. These lenses provide convenience and eliminate the need for daily removal. They are manufactured using highly breathable materials that enable a greater level of oxygen to reach the eyes, minimizing the likelihood of discomfort and complications.
- Disposable lenses are commonly chosen for their ease and cleanliness. They are designed to be used only once and thrown away after a certain timeframe, which is usually every day, every two weeks, or every month. This eliminates the need for cleaning and decreases the chances of getting eye infections. There are various types of disposable lenses to choose from, including soft lenses, toric lenses, and multifocal lenses.
- Orthokeratology lenses, also known as Ortho-K lenses, are a type of gas-permeable lenses that can reshape the cornea while sleeping in order to correct vision problems. These lenses are only worn at night and can temporarily improve vision during the day without needing to be worn during the day. Ortho-K lenses are especially beneficial for people with nearsightedness or myopia.
- Scleral lenses are bigger and cover a larger part of the eye, including the white outer layer (sclera). They enhance vision and provide comfort, especially for people with irregularly shaped corneas or those with conditions like keratoconus.
- Specialty lenses cater to specific eye conditions or abnormalities. They consist of toric lenses for astigmatism, multifocal lenses for presbyopia, and personalized lenses for individuals with severe refractive error or corneal irregularities. These lenses are tailored to meet the unique requirements of each person.
The presence of a variety of contact lenses allows people to discover the perfect option for enhancing their eyesight. It is important to seek advice from an eye specialist or optometrist to identify the best type of lens according to individual needs and eye condition. By choosing wisely and taking good care of them, contact lenses can correct vision effectively and provide comfort and convenience in everyday activities.
