👓 Spectacle Lens – Clear Vision, Personalized Comfort

Spectacle lenses are the core component of eyeglasses, designed to correct refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia. Modern lenses go far beyond simple vision correction—many now offer coatings and treatments that enhance comfort, durability, and eye protection.

🔍 Types of Spectacle Lenses:

1. Single Vision – Corrects one field of vision (near or distance).

2. Bifocal – Two optical powers, usually for distance and reading.

3. Progressive (Multifocal) – Smooth transition between multiple prescriptions.

4. Photochromic – Darken when exposed to UV light (e.g., Transitions® lenses).

5. Polarized – Reduce glare, ideal for outdoor use.

🌟 Advanced Features:

• Anti-reflective coating – Reduces glare and improves night vision.

• Scratch-resistant coating – Enhances lens durability.

• Blue light filtering – Protects against digital eye strain.

• UV protection – Shields eyes from harmful ultraviolet rays.

• Aspheric lenses – Thinner, lighter, and more natural appearance.

🩺 Common Use Cases:

• Prescription correction

• Digital eye strain relief

• Occupational eyewear (e.g., computer lenses, safety glasses)

• Fashion and personal style
