Contact lenses have become a popular option for many individuals seeking vision correction. They provide an alternative to traditional eyeglasses, offering freedom of movement and, in many cases, improved aesthetics. But with so many types of lenses available, how do you and your optometrist determine which ones may suit your lifestyle and vision needs?
What Are the Different Types of Contact Lenses?
Contact lenses come in several distinct types, each type is designed to address specific vision needs and preferences. It’s best to confer with your optometrist when selecting contact lenses, as some types are better suited for certain eye conditions. Here’s a breakdown of the major categories.
Soft Contact Lenses
Soft contact lenses are made from soft plastics, making them flexible and lightweight. They are one of the most commonly used lenses. These lenses can be used for individuals with common refractive errors, such as nearsightedness, farsightedness, or astigmatism. They are highly breathable, but may be less durable than more rigid contact lenses.
Rigid Gas-Permeable (RGP) Contact Lenses
Rigid gas-permeable lenses are made of durable plastic materials that enable high oxygen transmission. Unlike soft lenses, they retain their shape when inserted, offering sharper vision and correcting more complex vision issues. They last longer than softer lenses, but they could be less suitable for more sensitive eyes.
Scleral Contact Lenses
Scleral lenses are larger, rigid lenses that cover not only the cornea but also rest on the sclera (the white part of the eye). Originally designed for patients with unique eye conditions, scleral lenses are now a versatile option for individuals with dry eyes or irregular corneas. They may cost more than other types of contact lenses, but could be more comfortable to wear for some.
Extended Wear Contact Lenses
Extended wear lenses are designed for continuous use, including overnight wear, for up to a week or longer (depending on the type). These lenses appeal to individuals who prefer minimal replacement. Because of their nature, they do require diligent hygienic practices to avoid eye infections.
Specialty-Hybrid Contact Lenses
Hybrid contact lenses combine the technologies and materials used in rigid gas-permeable lenses and soft lenses. They feature a rigid center for sharp vision correction and a soft outer skirt for enhanced comfort. This kind of contact lenses is fairly new, so some eye care professionals may not be prepared to fit them.
How Do They Compare to Each Other?
Each type of contact lens offers unique advantages and challenges. While choosing a lens, it’s helpful to compare its features based on several factors. Some factors to note include comfort, durability, vision correction, and lifestyle compatibility.
Comfort Levels
Soft contact lenses are typically the most comfortable option for most individuals, especially for those new to lenses. Rigid gas-permeable lenses may feel less comfortable initially but are preferred for their superior visual clarity once adjusted. Hybrid lenses combine both comfort and clarity, making them a middle-ground option.
Maintenance and Durability
Soft lenses typically require regular replacement and careful cleaning due to their delicate material. Rigid gas-permeable lenses are far more durable, and their longer lifespan offsets the initial cost. Scleral lenses and hybrid lenses also require diligent cleaning due to their design but offer lasting durability when maintained properly.
Speaking With Your Optometrist
When selecting contact lenses, it’s valuable to weigh the benefits and limitations of each type. Keep in mind your vision correction needs, daily routine, and budget before making a decision. While online resources provide valuable preliminary insights, scheduling an appointment with an optometrist remains a fundamental step. A professional can recommend the most suitable lenses after examining your eyes and understanding your unique requirements.
