- Soft Contact Lenses
- Rigid Gas Permeable (RGP) Contact Lenses
- Disposable/ Frequent Replacement Contact Lenses
- Toric Contact Lenses
1. Soft Lenses
Benefits:
- Soft contact lenses are simple to wear because of their flexible plastic material
- They are more comfortable than rigid gas permeable lenses
- They are compatible with almost anyone who wants to wear contact lenses because of their adaptable design and material
2. Rigid gas permeable lenses
Rigid gas permeable contact lenses (RGPs) are more durable and resistant to deposit buildup, and generally give a clearer, crisper vision. They tend to be less expensive over the life of the lens since they last longer than soft contact lenses. They are easier to handle and less likely to tear. However, if you choose these types of contact lenses, it may take you a few weeks to get used to wearing them as they are not as comfortable as soft lenses. Not very common among Contact lens wearers due to a steeper adaptation curve in terms of comfort.
Benefits:
- Such type of contact lenses lasts longer as they are less likely to tear because of their durable material
- They are also cost-effective because of their long life
3. Disposable/Frequently Replacement Contact Lenses
The majority of soft contact lens wearers have been prescribed some type of frequent replacement schedule.“Disposable,” as defined by the FDA, means used once and discarded. They are available as daily disposable, monthly disposable, quarterly disposable, and yearly disposable. Some soft contact lenses are referred to as“disposable” by contact lens sellers, but actually, they are for frequent/planned replacement. With extended wear lenses, the lenses may be worn continuously for the prescribed wearing period (for example, 7 days to 30 days) and then thrown away.
- Daily Disposable lenses are easy to manage without any hassle of cleaning or disinfecting them
- Daily Disposables are also beneficial for traveling purposes when you can easily stock up on contact lenses to last the trip
- Monthly disposable, quarterly, and yearly disposable contact lenses are easily reusable after cleaning them with a soft contact lens care solution
4. Toric Orthokeratology(Ortho-K) Contact Lenses
Orthokeratology, or Ortho-K, is a lens fitting procedure that uses specially designed rigid gas permeable (RGP) contact lenses to change the curvature of the cornea to temporarily improve the eye's ability to focus on objects. This procedure is primarily used for the correction of myopia (nearsightedness). Overnight Ortho-K lenses are the most common type of Ortho-K. There are some Ortho-K lenses that are prescribed only for daytime wear. Overnight Ortho-K lenses are commonly prescribed to be worn while sleeping for at least eight hours each night. They are removed upon awakening and not worn during the day. Some people can go all day without their glasses or contact lenses. Others will find that their vision correction will wear off during the day. The vision correction effect is temporary.
Benefits:
- Toric lenses have different focusing or refractive powers on the vertical and horizontal orientations
- These contact lenses can be worn for extended periods at a stretch as they have high breathability
- They are also available as daily disposable contact lenses
