Contact lenses are very easy to put on, but if you don't choose the right one for you, you can have a lot of problems. There are many different options on the market today, and the choice can seem overwhelming. Knowing the pros, cons, and best uses of each type of contact lens can help you make the decision easily and provide the best option for your eyes.

Part 1: Evaluation of soft contact lenses

1. Learn about the different soft lens options. There are many different types of soft lenses available to suit your needs. In general, soft lenses are easier to adjust than hard breathable lenses. Soft lenses also tend to be more comfortable, especially when worn for extended periods of time.

Extended wear lenses - Can be worn overnight and for up to 7 days without removing the lenses.

Plan to change lenses - Should not be worn overnight. It must be replaced regularly, usually every two, four, or 12 weeks.

Silicone lenses - These lenses are breathable and prevent deposits from building up. This can make the lenses more comfortable with less risk of irritation, especially if you suffer from dry eyes.

Colored soft lenses - These soft lenses have a light tint. The tint may be functional (easier to find missing lenses) without changing the color of your eyes, or it may be cosmetic that makes your eye color different from your natural color.

2. Determine the duration of the shot. While soft lenses are generally better for extended wear, they don't have the lifespan of hard breathable lenses; however, you can reuse them for how long before you need to replace the lens. 

Daily disposable lenses - These lenses will cost more due to how often they are discarded; however, changing lenses daily have the lowest risk of infection. These lenses are a great option for people with dry eyes or prone to allergies because you have a new lens every day so there is less time for deposits and allergens to build up.

Biweekly/monthly disposable lenses - These lenses are slightly less expensive than daily disposable lenses and still help reduce the risk of infection by using new lenses every few weeks. Some disposable soft lenses can even be replaced every three months, but you should always follow the advice of your optometrist.

3. Determine if UV protection is important. Many people choose contact lenses because they can be worn while exercising without causing damage like glasses. If you play sports outdoors, or if you typically spend a lot of time in the sun, you may want to consider talking with your optometrist about soft lenses with UV protection.

It's important to note that not all soft lenses offer UV protection, although many do. If UV protection is a factor in your decision, discuss your options with your optometrist.

Comprehensive eye protection is important, UV protection on exposure only protects part of the eye. The rest of the eye should also be protected, so even if your contact lenses provide UV protection, you should still wear sunglasses outdoors.

4. Understand the shortcomings of soft mirrors. For many people, soft lenses are more comfortable and better suited to their needs than hard breathable lenses; however, soft lenses often do not correct vision as well as hard lenses. There are some other drawbacks worth considering.

Soft lenses are more likely to absorb environmental pollutants than hard lenses. If you are constantly around smoke or airborne particles, you may want to speak with your optometrist to determine if soft lenses are causing problems.

In addition to environmental pollutants, soft lenses tend to absorb irritants from the hands, including lotions and hand sanitizers. Washing your hands before handling lenses can reduce this risk, although it will not eliminate the chance of absorption.

Due to their soft, porous nature, these contact lenses are more fragile than hard lenses. As a result, they may rip or tear more easily (though they should be replaced more frequently).

Part 2: Considering rigid gas permeable (RGP) contact lenses

1. Understand the advantages of RGP lenses. RGP lenses tend to be less popular than soft lenses for a number of reasons, but RGP lenses excel in many areas. RGP lenses will provide most contact lens users with the following benefits:

Provides clearer vision than soft lenses

Provides better visual clarity for some users with astigmatism

Suitable for some presbyopic users who need bifocal or multifocal

Provides better fit and clarity for users with keratoconus (keratoconus)

For those who need contact lenses after refractive surgery

Can be used for orthokeratology, where lenses are worn at night to reshape the cornea

2. Understand the shortcomings of RGP lenses. Although RGP lenses are more suitable for certain users with specific needs, these lenses also have some disadvantages. Some users report that RGP lenses may have the following disadvantages:

They take longer to get used to and may be less comfortable.

They need to be worn regularly for the user to feel comfortable (even after a week without lenses).

Due to the smaller lens size, there is a greater risk of RGP lenses falling off during physical activity.

There is a higher risk of discomfort or corneal abrasions due to the increased likelihood of dust/debris remaining under the lens.

They require more care and maintenance than soft lenses; however, they tend to last longer, which may save you money in the long run.

3. Consider hybrid contact lenses. If you're skeptical of soft and RGP lenses, you may want to consider trying hybrid contact lenses. Hybrid lenses are made from a rigid, breathable center, but have a soft ring around the RGP component. This gives you the comfort of soft lenses while meeting the specific needs of some users for rigid lenses.

Hybrid lenses can be used to correct nearsightedness, farsightedness, astigmatism, age-related loss of myopia, and keratoconus.

Many users who require hard lenses find hybrid contact lenses more comfortable and easier to wear.

Part 3: Assess your needs

1. Perform eye examination and fitting. Before you choose contact lenses or any type of eyeglasses, be sure to have a thorough examination and fitting with an eye specialist. An eye exam is required to determine your lens strength and to obtain a contact lens prescription. Fitting is necessary to make sure your lenses fit the shape of your eye and fit your needs comfortably.

After receiving your lenses, you will most likely need one or more follow-up tests. These are usually scheduled a week after getting the lenses, then a month or six months later, and then once a year.

2. Consider how often you wear contact lenses. If you plan to wear contact lenses every day, you have the flexibility to choose between soft or hard lenses; however, if you only plan to wear your lenses on weekends or special occasions, soft lenses are the best option.

While soft lenses can be comfortably worn part-time or full-time, hard lenses must be worn full-time to maintain eye comfort.

3. Determine the importance of vision. Any contact lens will correct your vision and provide clearer vision than no contact lens; however, rigid lenses are generally considered to provide the clearest vision with any type of contact lens, especially for users with astigmatism.

If you need clarification or near-perfect working vision, consider talking with an eye specialist about whether hard lenses are best for you.

4. Determine how much care/effort you can put in. Improper lens care can lead to a range of vision problems, including fungal infections, bacterial infections, and corneal ulcers. Both soft and hard lenses require daily cleaning. The exception is daily disposable contacts, which are discarded at the end of the day.

Since soft lenses are usually replaced daily, weekly, or monthly, there is less risk of irritation or infection from buildup on the lenses.

If you don't mind taking extra care and maintenance to keep your contact lenses in good shape, then hard lenses may be right for you; however, if you're concerned about your ability to care for your lenses (including the risk of losing them), you may want to consider Use soft lenses.
