Types of Contact Lenses
Contact lenses are a popular alternative to glasses, offering a convenient and effective way to correct vision. Various types of contact lenses cater to different vision needs and lifestyles.
Soft Contact Lenses
Soft Contact Lenses are the most commonly prescribed type due to their comfort and flexibility. They conform to the shape of your eye, making them easy to adapt to.
- Daily Wear Lenses: Designed for daily use and removed every night.
- Extended Wear Lenses: Can be worn overnight for up to 30 days.
- Disposable Lenses: Used for a specific period (daily, weekly, or monthly) and then discarded.
Rigid Gas Permeable (RGP) Lenses
RGP Lenses are durable and provide clear vision. They are less comfortable initially but offer excellent correction for astigmatism and other irregular corneal conditions.
Toric Lenses
Toric Lenses are specially designed for people with astigmatism. They have different powers in different meridians of the lens to correct the uneven curvature of the eye.
Multifocal Lenses
Multifocal Lenses are designed to correct presbyopia, allowing for clear vision at multiple distances. They come in both soft and RGP varieties.
Coloured Contact Lenses
Coloured Contact Lenses are available for both cosmetic purposes and vision correction. They can change or enhance your eye colour while correcting your vision.
How to Choose the Right Contact Lenses
Choosing the right contact lenses depends on several factors, including your vision needs, lifestyle, and eye health. Here are some considerations:
Prescription Needs
- Nearsightedness (Myopia): Requires lenses that focus light correctly onto the retina.
- Farsightedness (Hyperopia): Needs lenses that adjust focus for distant objects.
- Astigmatism: Toric lenses are designed for this condition.
- Presbyopia: Multifocal lenses help with age-related vision changes.
Lifestyle
- Active Lifestyle: Daily disposable lenses are convenient for sports and outdoor activities.
- Long Hours: Extended wear lenses are suitable for people who prefer not to remove their lenses daily.
Eye Sensitivity
- Dry Eyes: Certain lenses, like silicone hydrogel, retain moisture better.
- Allergies: Daily disposables reduce the risk of buildup of allergens and proteins.
Aesthetics
- Natural Look: Coloured lenses can enhance or change your eye colour for a natural or dramatic effect.

Contact lenses offer numerous benefits over traditional eyeglasses:
