Definition of Contact Lenses
Contact lenses are medical devices worn on the surface of your eyes that provide vision correction. They are thin, curved pieces of plastic that sit directly on the cornea and can be used to correct nearsightedness, farsightedness, astigmatism, and presbyopia. Contact lenses come in both hard (rigid gas permeable) and soft (hydrogel) varieties.
Hard contact lenses are made from a rigid material such as polymethylmethacrylate (PMMA). These lenses provide excellent vision correction but take some time for users to become accustomed to them as they don’t conform to the shape of the eye like soft contact lenses do. Hard contacts also require more maintenance than soft contacts as they need regular cleaning and disinfecting with special solutions.
Soft contact lenses have a greater range of prescription powers available compared to hard contacts and therefore may be better suited for people with more severe vision impairments. Soft contact lenses are made from hydrophilic plastics that allow oxygen to flow through them which is beneficial for eye health. Unlike hard contact lenses, they form a suction cup effect when placed on the eye allowing them to fit snugly against its surface providing better comfort and stability during wear time. The implantable contact lens cost can vary greatly depending on the type of lens, the procedure itself, and other factors.
Types of Contact Lenses
Contact lenses are a great alternative to glasses, providing a comfortable and convenient solution for vision correction. The two main types of contact lenses available today are soft and rigid gas permeable (RGP) lenses. Each type varies slightly in terms of design, material, and how they interact with the eye.
Soft Contact Lenses:
Soft contact lenses are made from flexible hydrogel materials that help keep the lens moist against your eye. These special materials also help make it easier for oxygen to reach the cornea, helping to keep your eyes healthy while wearing them. Soft lenses typically provide more comfort than RGP lenses due to their flexibility and ability to conform easily to the shape of your eye. They come in both disposable daily wear options or extended wear options which allow you to sleep with them overnight without needing to take them out each day. A soft contact lens can also be used for vision correction as well as cosmetic purposes such as changing or enhancing eye color or enlarging pupils for a more dramatic look.
Advantages of Wearing Contact Lenses
Contact lenses offer a number of advantages to those looking for an alternative to glasses. They are more discreet, allowing you to go about your daily activities without the bulk and weight of glasses. They also provide a wider field of vision than glasses, as they cover the entire eye area. Additionally, contact lenses can help improve peripheral vision and depth perception.
One of the most significant advantages of wearing contact lenses is that they allow you to maintain your appearance without having to hide behind a pair of glasses. Glasses can be uncomfortable and unsightly, making them an unattractive option for those who want their appearance to remain unchanged by eyewear. Contact lenses provide a natural look while still providing clear vision.
Another advantage is that contact lenses may be easier on the eyes than glasses because they don’t have frames or edges that could cause irritation or pressure on the sensitive areas around your eyes like some traditional frames may do. Furthermore, contacts are designed with special coatings that act as protective barriers against dust and debris from getting into your eyes so you can feel comfortable in any environment without worrying about debris entering your eye area when wearing contacts instead of glasses.

Disadvantages of Wearing Contact Lenses
When it comes to improving your vision, contact lenses can be a great alternative to eyeglasses. However, with any medical device, there are some potential risks and drawbacks that you should consider before making the switch. Here are some of the disadvantages of wearing contact lenses:
1) Poor Hygiene Habits: Wearing contact lenses requires proper hygiene habits to prevent eye infections and irritation. You must clean your hands thoroughly with soap and water before handling your contacts, and make sure they’re cleaned properly each day. If you don’t follow these steps, you could end up with an infection or allergic reaction in your eyes.
2) Costly Maintenance: Contact lenses require regular care and maintenance such as cleaning solutions and replacement lens cases. Over time these costs can add up considerably if you don’t take good care of them or use reusable contacts instead of disposables.
3) Dry Eyes: Prolonged wear of contact lenses can cause dry eyes due to decreased tear production. This can lead to further discomfort for those already suffering from dry eye syndrome or allergies that cause itchy eyes.
Care and Maintenance of Contacts
Contacts are an increasingly popular choice for vision correction, as they offer many advantages over glasses. However, contacts also require more care and maintenance than glasses do. In order to maintain healthy eyes and clear vision, it is important to take proper care of your contact lenses.
Cleaning: It is essential to clean your contact lenses each time you remove them from your eyes. Use a specially-formulated contact lens solution and a soft cloth to gently rub the lenses on both sides, then rinse before soaking in the solution overnight or for at least four hours. Never use tap water; it can contain bacteria that can cause serious eye infections if introduced into the eye via contact lenses.
Disinfecting: All contact lenses need disinfection in order to protect against microorganisms that may be on the lens surface from everyday wear and tear. Disinfection typically requires soaking in a specific multi-purpose or hydrogen peroxide solution overnight, followed by rinsing with sterile saline before wearing again the next day.
Replacing: Replacing your contacts regularly is essential for maintaining good ocular health—even if you’re using daily disposable contacts or extended-wear contacts! Even with frequent cleaning, deposits can build up on the surface of reusable contacts over time.
Conclusion
Implantable contact lenses are an exciting new advance in vision correction technology. They offer a permanent, non-surgical solution for those with refractive errors who want to stop relying on glasses or contact lenses. While the procedure is still relatively new, it has been safely and successfully used to treat patients with mild to moderate nearsightedness and astigmatism since the late 1990s. With continued research, implantable contacts may eventually become an even more widely accepted and viable option for many people looking for improved visual quality.
