All about Contact Lenses
Contact lenses are thin, curved lenses placed on the film of tears that cover the surface of your eye. They work by changing the direction of light as it enters your eye, focusing light directly onto the retina for clear vision.
Contact lenses correct refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia.
Types of Contact Lenses
There are different types of contact lenses. Each offers various benefits and is designed to address different vision needs.
Soft Contact Lenses
Soft contact lenses are flexible plastic that allows oxygen to pass through to the cornea. They are comfortable, easy to adapt, and suitable for first-time contact lens wearers.
Rigid Gas Permeable (RGP) Contact Lenses
Rigid gas-permeable contact lenses are made of durable plastic that transmits oxygen. They provide crisp vision and can correct a wide range of refractive errors.
RGP lenses maintain the eye shape, which can offer some users clearer vision than soft lenses. They are also more resistant to deposit buildup, making them easier to clean and care for.
Hybrid Contact Lenses
Hybrid contact lenses have a rigid gas-permeable centre surrounded by a soft outer ring. They provide the clear vision of RGP lenses with the comfort of soft lenses. These lenses suit people with irregular corneas or those with difficulty with other lenses.
Scleral Contact Lenses
Scleral contact lenses are large and vault over the entire corneal surface, resting on the sclera (the white part of the eye). They are used for hard-to-fit eyes and can improve vision for people with corneal irregularities.
Disposable Contact Lenses
Disposable contact lenses are to be worn once and then discarded. They offer the ultimate in convenience and hygiene.
Disposable contact lenses provide a fresh, clean lens, reducing the risk of deposit buildup and eye irritation. They are suitable for people with allergies or difficulty cleaning and storing lenses.
Coloured Contact Lenses
Coloured contact lenses are available for both prescription and non-prescription use. They can enhance or change the colour of your eyes and are available in various tints and colours.
Choosing the Right Contact Lenses
When choosing the right contact lenses, some key factors to consider include:
Eye Condition
Your eye condition, such as myopia, hyperopia, astigmatism, or presbyopia, will determine the type of contact lenses needed. An eye exam determines the proper prescription and type of lens that can best address your eye condition.
Lifestyle
Your lifestyle, visual demands, occupation, and hobbies are crucial in selecting appropriate contact lenses. For example, if you have a sedentary job or spend too much time on the computer, you may need contact lenses with high moisture content or suitable for computer vision syndrome.
Maintenance Requirements
Different types of contact lenses have varying maintenance requirements, such as daily disposable, bi-weekly/monthly replacements, or extended-wear lenses. Consider your preferences and abilities when choosing contact lenses.
Daily Activities
Your daily activities, such as sports, physical activities, or screen time, can also influence your choice of contact lenses. Some lenses are for extended wear and may be more suitable for those who engage in activities requiring long focus periods.
Prescription
Your prescription will determine the type and power of contact lenses needed. Consult with optometrists to ensure you receive the correct prescription for your specific needs.
Caring for Contact Lenses
Proper Hygiene Practices
- Importance of Washing Hands Before Handling Lenses
It is crucial to thoroughly wash and dry your hands before handling contact lenses to prevent transferring harmful microorganisms, such as bacteria or fungi, to your eyes. Using a mild, non-perfumed soap will help avoid any irritation that fragrances or harsh chemicals could cause.
- Cleaning and Storage Routines for Different Types of Lenses
Regular cleaning and proper storage of contact lenses are key to maintaining their effectiveness and preventing eye infections.
For soft lenses, rinse and disinfect them every time you remove them. With RGP lenses, you will need to use a special cleaning solution.
Always ensure the lens case is clean and dry before storing the lenses. Regardless of the type, never rinse or store contact lenses in water, and always replace the storage solution after each use.
Prevention of Eye Infections
- Tips to Avoid Eye Infections While Wearing Contact Lenses
Never sleep in your contact lenses to prevent eye infections unless they’re designed for extended wear. Also, avoid wearing contacts in water-filled environments like swimming pools or hot tubs, as they’re breeding grounds for bacteria and other microorganisms.
Regularly clean and replace the case of your lens to eliminate microbial growth.
- Significance of Regular Check-Ups and Lens Replacements
Regular check-ups with optometrists are crucial to ensure your eyes remain healthy. Additionally, always replace your lenses as instructed by the eye care professional. Overusing lenses can lead to eye discomfort and infections.
