Contact lenses are thin, transparent devices placed on the eye's surface to correct vision or for cosmetic purposes. They come in soft or rigid materials and are used as an alternative to eyeglasses for various vision issues. It's essential to use them responsibly and follow proper hygiene guidelines to prevent eye problems.
Contact lenses have transformed vision correction, offering comfort and convenience to millions. From soft to rigid, and therapeutic to cosmetic, a variety of contact lenses cater to diverse needs. Let's explore the main types:
Soft Contact Lens:
Popular for their comfort, soft lenses are made of flexible, water-containing materials. They correct myopia, hyperopia, and astigmatism. Available in various modalities.
Rigid Gas Permeable (RGP) Lens:
Durable and oxygen-permeable, RGP lenses provide excellent visual acuity. Ideal for complex prescriptions and astigmatism.
Scleral Contact Lens:
Large gas permeable lenses that vault over the cornea, useful for irregular corneas like keratoconus. Improve visual clarity and comfort.
