FAQs- Sunglasses Collection FAQs

1. What does UV400 protection mean?

UV400 protection blocks 100% of harmful UVA and UVB rays with wavelengths up to 400 nanometres. It helps protect your eyes from long-term sun damage while reducing glare and improving visual comfort.

All By Charley sunglasses feature UV400 protection, making them suitable for everyday wear, driving and outdoor activities.

2. What are polarised sunglasses?

Polarised sunglasses use a special filter that reduces glare reflected from surfaces such as roads, water and glass. This provides clearer vision, better contrast and improved visual comfort.

Polarised lenses are especially popular for driving, travelling, fishing and spending time outdoors.

3. Are all your sunglasses UV400 protected?

Yes. Every pair of By Charley sunglasses offers UV400 protection to help shield your eyes from harmful ultraviolet rays while maintaining clear, comfortable vision.

4. Are polarised sunglasses better?

Polarised sunglasses are ideal if you spend time outdoors or drive regularly because they reduce glare and improve visual clarity. However, for general fashion and everyday use, both polarised and non-polarised sunglasses provide UV protection when they feature UV400 lenses.

5. Can I wear sunglasses every day?

Absolutely. Wearing sunglasses every day helps protect your eyes from UV exposure and can reduce eye strain caused by bright sunlight.

Lightweight frames and comfortable designs make sunglasses suitable for daily wear throughout the year.

6. How do I clean my sunglasses?

Clean your sunglasses using the included microfibre cloth. If necessary, rinse the lenses with lukewarm water and use a small amount of mild soap before drying with a clean microfibre cloth.

Avoid paper towels, tissues and abrasive cleaners, which may scratch the lenses.

7. Can sunglasses get wet?

Yes. Occasional exposure to water won't normally damage your sunglasses. However, after contact with saltwater or chlorinated water, rinse them with fresh water and dry them thoroughly to help protect the lenses and frame.

8. How should I store my sunglasses?

Store your sunglasses in a protective case when not in use. Keeping them inside a case helps prevent scratches, dust and accidental damage.

Avoid leaving sunglasses in extremely hot places, such as on a car dashboard, for extended periods.

9. What face shape suits cat-eye sunglasses?

Cat-eye sunglasses are flattering on many face shapes, especially round, oval and heart-shaped faces. Their lifted corners help create a more defined and elongated appearance.

10. Which sunglasses suit a round face?

Rectangle, square and cat-eye sunglasses often complement round faces by adding definition and balance. Slightly oversized frames can also create a flattering silhouette.

11. Which sunglasses suit an oval face?

Oval faces are considered the most versatile and suit almost every frame style, including cat-eye, rectangle, oval, aviator and square sunglasses.

12. Which frame material is best?

Different materials offer different benefits.

• TR90 is lightweight, flexible and comfortable.
• Acetate provides a premium feel and rich colours.
• Metal frames offer a timeless minimalist look.
• Recycled PC is lightweight and supports a more sustainable choice.

The best material depends on your personal style and lifestyle.

13. How long do sunglasses last?

With proper care, quality sunglasses can last for many years. Keeping them in a protective case, cleaning them correctly and avoiding unnecessary impact helps maintain both the lenses and frames.

14. Are your sunglasses suitable for driving?

Yes. UV400 protection helps protect your eyes from harmful UV rays, while polarised lenses reduce glare from roads and vehicles, making them an excellent choice for driving during the day.

15. Can scratched lenses be repaired?

Minor surface marks cannot usually be removed without affecting the lens coating. Deep scratches generally require replacing the lenses or the sunglasses.

To help prevent scratches, always store your sunglasses in their protective case and clean them with a microfibre cloth.

16. Are your sunglasses suitable for sensitive skin?

Yes. Our sunglasses are designed with lightweight, comfortable materials for everyday wear. Many styles feature smooth finishes and hypoallergenic components to improve comfort during extended use.

17. Do sunglasses protect against blue light?

Standard sunglasses are designed primarily to protect against UV rays and reduce visible glare. They are not intended to function as blue light glasses for digital screen use unless specifically stated.

18. What's the difference between UV400 and polarised lenses?

UV400 and polarised lenses serve different purposes.

UV400 protection blocks harmful UVA and UVB rays to help protect your eyes from sun damage. Polarised lenses reduce glare reflected from flat surfaces, improving visual clarity and comfort. Many premium sunglasses combine both features for the best outdoor experience.
