1. Understanding the Types of Contact Lenses

Before you delve into the world of contact lenses, it’s crucial to understand the various types available and find the most suitable option for your vision needs and lifestyle. The main categories of contact lenses include:

• Soft Lenses: Made from hydrogel materials that contain water, soft lenses are known for their comfort and flexibility. They are the most popular type of contact lens on the market and accommodate a wide range of prescriptions, including single-vision, multifocal, and astigmatism correction.
• Silicone Hydrogel Lenses: A more advanced type of soft lens, silicone hydrogel lenses allow more oxygen to pass through to the cornea. They are known for their breathability, enhancing comfort and reducing the risk of eye irritation.
• Gas-permeable (GP) Lenses: Rigid and breathable, GP lenses allow more oxygen to reach the eye than soft lenses. They provide superior visual acuity and can be customised for various vision problems, including astigmatism and presbyopia.
• Hybrid Lenses: Combining the benefits of both soft and GP lenses, hybrid lenses feature a rigid centre for sharp vision and a soft outer ring for comfort. These lenses cater to those who desire exceptional visual clarity yet struggle to adapt to traditional GP lenses.

2. The Contact Lens Fitting Process

Once you’ve decided on the type of contact lens that best suits your needs, it’s essential to undergo a professional fitting process. The contact lens fitting process consists of several steps:

• Comprehensive Eye Examination: To ensure your eyes are healthy and suitable for contact lens use, a complete eye examination will be conducted. This exam assesses your overall eye health and determines your prescription for lenses.
• Contact Lens Evaluation: Your optometrist will measure the shape and size of your cornea, as well as evaluate the tear film on the surface of your eye. These measurements ensure a proper fit and help determine the most suitable lens type for your eyes.
• Trial Fitting: You’ll be provided with trial contact lenses to test their fit and comfort on your eyes. During this trial period, your optometrist will assess lens movement, centration, and overall fit to confirm the best contact lens option for you.
• Instruction and Training: If you’re new to contact lenses, you’ll receive detailed guidance on proper lens insertion, removal, and care practices. This essential training lays the foundation for successful contact lens use and reduces the risk of complications.

3. Taking Care of Your Contact Lenses

Proper contact lens care is essential to maintain eye health, avoid infection, and prolong the life of your lenses. The primary care practices are:

• Hand hygiene: Always wash your hands thoroughly with soap and water before handling your lenses to minimise the risk of infection.
• Cleaning and storage: Follow the recommended cleaning and storage procedures for your specific lens type. In general, you should use a lens case and lens solution to clean and store your lenses overnight. Never use water, as it can introduce harmful microorganisms.
• Replace lenses and cases regularly: Adhere to the replacement schedule recommended by your optometrist, whether daily, weekly, or monthly. Don’t stretch the use of your lenses beyond their intended lifespan. Likewise, replace your lens case every three months to avoid bacterial contamination.

4. Potential Complications and How to Avoid Them

While contact lenses are generally safe and comfortable to use, potential complications can occur if proper care and hygiene measures aren’t followed. Some common complications include:

• Eye infections: Improper lens handling, storage, or cleaning can lead to the risk of eye infections. Always follow strict hygiene practices when using contact lenses.
• Corneal abrasions: Ill-fitting lenses or improper lens insertion/removal can scratch the cornea. Ensure your lenses fit correctly, and be gentle when handling them.
• Dry eyes: Prolonged contact lens use may lead to dry eyes. Use lubricating eye drops recommended by your optometrist and take breaks from lens wear if needed.
• Giant papillary conjunctivitis (GPC) is an allergic reaction to contact lenses, often caused by protein deposits on the lens surface. Regular lens cleaning and replacement can help prevent this condition.

By following expert advice from us, maintaining optimal lens hygiene, attending regular check-ups, and listening to your eyes, you can comfortably and successfully enjoy contact lens wear.
