Understanding the Different Types of Contact Lenses

Types Based on Material

Contact lenses are made from different materials that influence comfort, breathability, and durability. Our ophthalmologists perform a professional fitting to ensure you get the right material for your specific eye health, daily activities, and personal preferences.

Made from flexible, water-containing plastics called hydrogels, soft lenses conform to the surface of your eye and feel comfortable right away. They are the most popular type of lens because they allow oxygen to reach the cornea, reducing dryness. Ideal for active lifestyles, they move naturally with your eye and rarely fall out during sports or other activities. Soft lenses currently represent the vast majority of contact lens prescriptions because of their immediate comfort and ease of use.

RGP lenses are made from a firm, durable plastic that allows significant oxygen to pass through to the eye. They provide exceptionally sharp, crisp vision and are an excellent choice for correcting high astigmatism or conditions like keratoconus. While they require a brief adaptation period of a few days to a week, their durability and resistance to protein and deposit buildup make them a cost-effective option over time. Many wearers find the superior visual clarity worth the initial adaptation.

These advanced soft lenses combine the comfort of traditional hydrogels with the high oxygen permeability of silicone materials. They can transmit up to five or six times more oxygen to your cornea compared to regular soft lenses, which helps keep your eyes white, healthy, and comfortable. This makes them an excellent option for people who experience dryness or wear their lenses for long hours. Silicone hydrogel technology has become the standard for most modern contact lens prescriptions.

These specialty lenses are designed for situations where standard lenses may not work well. ReFocus Eye Health Penndel offers advanced fitting services for these complex lens types.

  • Hybrid lenses feature a rigid gas permeable center for sharp vision, surrounded by a soft outer skirt for enhanced comfort. This design provides the best of both worlds for patients who need crisp vision but struggle with traditional RGP comfort.
  • Scleral lenses are larger-diameter lenses that vault over the entire cornea and rest on the white part of the eye, called the sclera. This design creates a fluid-filled reservoir that provides constant moisture, making them an excellent solution for severe dry eye, irregularly shaped corneas, and conditions like keratoconus or post-surgical corneal irregularities.

Types Based on Wearing Schedule

Types Based on Wearing Schedule

The schedule for wearing and replacing your lenses impacts convenience, eye safety, and cost. Choosing the right schedule helps prevent infections and keeps your vision sharp while fitting your budget and lifestyle needs.

Daily disposables are designed for a single use and are thrown away at the end of the day. This makes them the most convenient and hygienic option, as there is no cleaning or storage required. They are an ideal choice for people with allergies, busy schedules, or for those who wear contacts only occasionally. Because you start each day with a fresh, sterile lens, daily disposables significantly reduce the risk of eye infections and are often recommended for teenagers and first-time wearers.

These lenses are worn daily and replaced every one to four weeks, offering a great balance of cost and convenience. They must be removed, cleaned, and stored properly each night using a disinfecting solution. With good maintenance habits and consistent care routines, they provide comfortable and safe vision for regular wearers. Monthly lenses are often more economical for full-time contact lens wearers.

Extended wear lenses are made from highly breathable materials approved for continuous wear, even overnight, for up to seven days or in some cases 30 days. This can be convenient for shift workers or those with unpredictable schedules. However, sleeping in contact lenses increases the risk of eye infections, so not everyone is a candidate. Close monitoring by your eye doctor is essential, and strict adherence to replacement schedules is required.

Specialty Contact Lenses

Specialty Contact Lenses

Specialty lenses provide tailored solutions for specific vision issues, complex prescriptions, or eye conditions that standard lenses cannot adequately address. Our team has extensive experience fitting these advanced lens designs.

Toric lenses have a special shape to correct astigmatism, a condition where an irregular curve in the eye causes blurry vision at all distances. They are designed with weighted areas or other stabilization features to keep them from rotating on the eye, ensuring your vision remains stable and clear throughout the day. A precise fitting is essential to get the best results, and modern toric lenses are available in soft, silicone hydrogel, and rigid gas permeable materials.

Multifocal lenses help people with presbyopia, the common age-related loss of near vision that typically begins in the early to mid-40s. They contain multiple prescription zones, much like progressive eyeglass lenses, to provide clear sight at all distances from near to far. This allows you to reduce or eliminate your dependency on reading glasses. Today's multifocal designs offer excellent visual quality for computer work, reading, and distance tasks.

Colored lenses can enhance or completely change your natural eye color, and are available with or without vision correction. Even if you do not need vision correction, colored lenses are considered medical devices and require a proper fitting and prescription from an eye doctor. Never buy lenses from an unlicensed source, costume shop, or online retailer without a prescription, as poorly fitting lenses can cause serious eye damage, infections, and even permanent vision loss.

Also known as corneal reshaping lenses, Ortho-K lenses are rigid, gas permeable lenses worn overnight. While you sleep, they gently and temporarily reshape your cornea to correct nearsightedness. The lenses are removed in the morning, providing clear vision throughout the day without the need for glasses or contacts. They are also a leading option for controlling myopia progression in children, with research showing they can slow axial elongation by 40 to 60 percent compared to regular glasses. This makes them an important tool for protecting long-term eye health in young, progressing myopes.

Contact Lens Care and Hygiene

Proper care is essential for safe and comfortable contact lens wear. Following good hygiene habits is the single most important way to prevent eye infections and other complications that can threaten your vision.

Always wash and dry your hands thoroughly with antibacterial soap and water for at least 20 seconds before handling your lenses. Use only the cleaning solution recommended by your eye doctor, and gently rub the lens with solution to remove deposits, even if using a no-rub formula. Always store your lenses in a clean case with fresh solution, never topping off old solution. Replace your lens case at least every three months, or sooner if it becomes cracked or cloudy.

Never use tap water, distilled water, saliva, or homemade saline to clean or store your lenses, as these can contain harmful microorganisms that cause severe infections. Do not swim, shower, or use a hot tub while wearing contacts. Water exposure is one of the leading risk factors for serious corneal infections. Never put lenses in your mouth to wet them, and do not ignore discomfort. If your eyes are red, painful, or irritated, remove your lenses immediately and contact our office.

Take your lenses out immediately if you experience any of the following symptoms:

  • Redness or irritation that does not go away quickly
  • Pain in or around the eyes
  • Sudden changes in vision or blurriness that does not clear with blinking
  • Unusual light sensitivity or halos around lights
  • Excessive tearing or unusual discharge
  • Feeling like something is stuck in your eye

If symptoms persist after removing your lenses and giving your eyes a break, contact ReFocus Eye Health Penndel right away for evaluation.

Getting Started with Contact Lenses

Getting Started with Contact Lenses

Your journey to successful contact lens wear begins with a professional fitting and training. Understanding what to expect helps you prepare for a smooth transition and the best possible experience with your new lenses.

A contact lens fitting is different from a regular eye exam. Your eye doctor will take specific measurements of your cornea's curve, diameter, and overall shape using specialized instruments. They will also evaluate your tear film quality and quantity to determine the best lens type for your unique eyes. The fitting includes a discussion of your lifestyle needs, work environment, hobbies, and vision goals. You will receive hands-on training on how to safely insert, remove, and care for your lenses before taking them home.

It is normal to be aware of the lenses in your eyes for the first few days. Your vision might fluctuate slightly as you get used to them, and your eyes may produce more tears than usual as they adapt. Most people adjust quickly and can wear their lenses comfortably all day within a week or two. Be patient with yourself and follow your doctor's recommended wearing schedule. Start with just a few hours the first day and gradually increase wear time as your comfort improves.

The total cost of contact lenses includes the initial fitting fee, the lenses themselves, cleaning solutions and supplies, and your annual comprehensive eye exam and contact lens evaluation. Many vision insurance plans offer an allowance that can be applied toward contact lens fittings and materials. Our knowledgeable staff can help you understand your benefits, explore manufacturer rebates, and find ways to make your lenses more affordable. We also offer flexible options for purchasing annual supplies that can reduce your overall costs.

Frequently Asked Questions About Contact Lenses

Frequently Asked Questions About Contact Lenses

Here are answers to some of the most common questions patients have about contact lenses. If you have other questions or concerns, our team is always here to help guide you.

Yes, contact lenses are very safe for motivated new wearers, including teenagers and even some responsible pre-teens. Success depends on the ability to handle and care for the lenses responsibly with proper hygiene and adherence to wearing schedules. Daily disposables are often an excellent starting point because they are easy to use and require no cleaning, minimizing the risk of infection. We work closely with young patients and their parents to ensure they understand all safety protocols before starting lens wear.

Your eye doctor is the only one who can determine this through a comprehensive evaluation. Our ophthalmologists will assess your prescription, eye health, corneal shape, tear film quality, and lifestyle needs. Factors like dry eyes, allergies, work environment, computer use, sports participation, and your daily schedule will all be considered to find your perfect match. We often provide trial lenses so you can experience the comfort and vision quality before making a final decision.

Yes, many people with dry eyes can successfully wear contact lenses with the right approach. Your doctor may recommend specific lens materials like silicone hydrogel for better oxygen flow, daily disposables to avoid deposit buildup, or specialty scleral lenses that bathe the eye in constant moisture. Treating the underlying cause of your dryness with therapies available at ReFocus Eye Health Penndel is also key. We offer comprehensive dry eye evaluations and treatments to help you wear contacts comfortably.

Yes, every contact lens wearer should have an up-to-date pair of backup glasses. You will need them for times when you should not wear your lenses, such as when your eyes are irritated, when you are sick with a cold or infection, during air travel, or simply to give your eyes a break in the morning and at night. Having quality backup glasses ensures you can always see clearly even when contacts are not appropriate.

No, you should never expose your contact lenses to any type of water. This includes tap water, swimming pools, hot tubs, lakes, rivers, and oceans. Water contains bacteria, amoebas, and other microorganisms that can cause severe, sight-threatening infections like Acanthamoeba keratitis. These infections are difficult to treat and can lead to permanent vision loss. Always remove your lenses before any water activities and wear prescription swim goggles if needed.

There are excellent specialty lens options available for complex prescriptions and corneal irregularities. Custom soft toric lenses, rigid gas permeable lenses, hybrid lenses, and scleral lenses can all provide sharp, stable vision for prescriptions that are outside the range of standard contacts. Our team has extensive experience fitting these specialized lenses and will work with you to find the option that provides the best vision and comfort for your unique eyes.

Both are options for correcting presbyopia, but they work in different ways.

  • Multifocal lenses have multiple prescription zones built into each lens to provide clear vision at all distances simultaneously. Your brain learns to select the appropriate zone for the task.
  • Monovision corrects one eye (usually the dominant eye) for distance vision and the other eye for near vision. Your brain learns to favor the appropriate eye for each task, whether looking at your phone or driving.

Your eye doctor can help you decide which option is a better fit for your visual needs and lifestyle through a trial fitting period. Some people adapt immediately while others need time to adjust or may prefer one method over the other.

Contact lens prescriptions are valid for one year. You should have a comprehensive eye exam and a contact lens evaluation annually to monitor the health of your eyes, ensure your lenses still fit properly, and keep your prescription current. During these visits, we check for any signs of complications from lens wear and make adjustments to optimize your comfort and vision. Regular annual exams are essential for safe, long-term contact lens wear.

Yes, but follow these important safety tips:

  • Always insert your lenses before applying makeup to avoid transferring cosmetics to the lens surface
  • Use oil-free, hypoallergenic products that are less likely to cause irritation
  • Avoid applying eyeliner to your inner eyelid margin or waterline, as this can contaminate your lenses
  • Remove your lenses before removing your makeup at the end of the day
  • Replace mascara and liquid eyeliners every three months to prevent bacterial growth and contamination
  • If makeup gets in your eye, remove your lens, rinse it thoroughly with solution, and reinsert only if comfortable

Never flush contact lenses down the toilet or wash them down the sink. They are not biodegradable and contribute to microplastic pollution in our waterways, eventually entering the food chain and harming aquatic life. The proper way to dispose of used lenses is to throw them in the solid waste trash. Some programs also accept lens blister packs for recycling, so ask our staff about environmentally responsible disposal options.
