Understanding the Different Types of Contact Lenses
Contact lenses come in various forms to meet diverse visual needs and preferences. Knowing your options can help you select the most suitable lenses for comfort, convenience, and budget. The primary categories are soft and rigid gas permeable (RGP) lenses, each with unique characteristics.
Soft lenses, made from hydrogel or silicone hydrogel, are lightweight and comfortable. They correct common issues like nearsightedness, farsightedness, astigmatism, and presbyopia. Available in daily, bi-weekly, or monthly disposables, as well as extended-wear variants, they provide flexibility based on lifestyle.
Daily disposable lenses offer convenience and lower infection risk since they are discarded after use. Bi-weekly lenses need regular cleaning, while monthly lenses are a cost-effective choice for daily wear. Extended-wear soft lenses, crafted from silicone hydrogel, can be worn continuously for up to 30 days without removal, ideal for busy schedules or those avoiding frequent maintenance. Colored lenses are available for cosmetic purposes, with options for prescription-based vision correction, compatible with myopia and hyperopia but less so for astigmatism.
Rigid gas permeable (RGP) lenses are durable and provide sharp vision. Though less popular today, they are advantageous for certain prescriptions and can last longer with proper care. RGP lenses are custom-made and may require an adjustment period but are highly effective for specific visual conditions.
