Frequently Asked Questions (FAQ)
Q1 What materials are commonly used for premium optical frames?

High-quality optical frames are typically crafted from durable materials such as lightweight titanium, premium acetate, stainless steel, and flexible TR90. Each material delivers distinct advantages in comfort, strength, and aesthetic appeal.

Q2 How do I determine the correct frame size for prescription lenses?

Frame dimensions are measured by lens width, bridge width, and temple length. Selecting a frame size that properly aligns your pupils with the optical center of each lens guarantees maximum visual clarity and comfortable daily wear.

Q3 Are anti-reflective and blue-light blocking coatings recommended?

Yes. Anti-reflective (AR) coatings minimize reflections for visual clarity, while blue-light blocking filters help alleviate digital eye strain caused by prolonged exposure to computer screens and mobile devices.

Q4 Can optical frames accommodate strong high-index prescription lenses?

Yes. Optical frames designed with optimal rim depth securely hold high-index lenses, reducing overall lens edge thickness and preserving a sleek, comfortable profile even for stronger prescriptions.

Q5 What is the proper way to clean and maintain optical eyewear?

Clean lenses using lukewarm water and a drop of neutral liquid soap or dedicated lens cleaning spray. Gently dry with a soft microfiber cloth. Avoid using harsh household chemicals or rough paper towels to prevent coating damage.

Q6 What is the standard production lead time for custom optical frame manufacturing?

Standard manufacturing lead times generally range from 30 to 45 days, depending on material complexity, customization requirements, and order batch sizes. Sample verification is completed prior to bulk production.
