If you are considering switching to contact lenses from eyeglasses, or you are already a contact lens wearer, you probably have several unanswered questions. Here is some valuable information about contact lenses and your eye health.

What Are Contact Lenses?

Contact lenses are thin, curved discs made of various materials, such as silicone or hydrogel. They are typically placed directly on your eye's surface. They correct refractive errors in the eye, such as nearsightedness or farsightedness.

What Contact Lens Types Are There?

You can find the following types of contact lenses:
 

• Soft Contact Lenses - They comprise a flexible plastic material that conforms to your eye shape. They are comfortable and wearable for extended periods
   

• Rigid Gas-permeable (RGP) Lenses - RGP contacts comprise gas-permeable materials that let oxygen into your eye. They provide clearer vision than soft contact lenses, although it might take some time to get used to
   

• Hybrid Contacts - Hybrid contact lenses have a rigid center surrounded by a soft outer ring. They provide the comfort of soft contact with the sharp vision of RGP lenses
   

• Extended-wear Contact Lenses - Extended-wear contact lenses can be worn continuously for several days without removal. But they are not suitable for everyone. They require careful monitoring by an eye doctor
   

• Daily Disposable Contact Lenses - Daily disposable contact lenses are worn for a single day and then discarded. They are convenient and require minimal maintenance. This has made them popular among many wearers

How Do I Choose Suitable Contact Lenses?

Choosing suitable and effective contacts depends on several factors. Your lifestyle, prescription, and comfort level determine the right fit for you. Consulting your eye doctor to determine the best type of contact lens that suits your particular needs is crucial.

Can Contact Lenses Correct Astigmatism?

Yes, contact lenses can correct astigmatism. Several types of astigmatism-correcting contact lenses are available. They include toric and hybrid lenses. Toric lenses have a unique shape, allowing them to fit securely on the eye and correct the refractive errors caused by astigmatism. Hybrid lenses have a rigid center surrounded by a soft outer ring, providing comfort and sharp vision correction for astigmatism.

Are Contact Lenses Safe?

Overall, contact lenses are safe when used properly under the supervision of an eye doctor. However, improper contact lens use can result in serious eye infections or complications. Following proper hygiene practices when handling and wearing contact lenses is vital. 

You must wash your hands before inserting or removing them, use a sterile solution to clean them, and replace them as your eye doctor recommends.

Can I Wear Contact Lenses While Swimming?

Wearing contact lenses while swimming or engaging in water activities is not advisable. Did you know contact lenses can trap bacteria and other microorganisms against the eye? This can significantly increase the risk of eye diseases. If you need vision correction while swimming or engaging in water activities, prescription goggles or swim masks are a safer alternative.

Conclusion

Consulting your eye doctor and following proper hygiene practices can help ensure the safe and effective use of contact lenses.
