Oakley HSTN Sunglasses - Celeste

BiO-Matter® is a plant-based material derived from castor oil, containing at least 56% bio-based carbon. It offers durability and lightweight comfort while being a more sustainable choice compared to traditional frame materials.

The HSTN sunglasses are designed with lifestyle and everyday performance in mind, featuring a secure fit and clear optics. While they offer good grip and durability, they are not specifically engineered for high-impact sports like Oakley's performance-focused lines.

Prizm Ruby Polarized lenses enhance color and contrast, reduce glare, and improve visual acuity in bright light conditions. This makes them excellent for everyday activities, especially in sunny environments.

The HSTN features modernized circular lenses, which tend to be versatile and can complement various face shapes. However, personal preference is key. Consider trying them on if possible or looking at reviews with different face shapes.

Oakley offers a lens replacement service for many of its models. Please check with Oakley customer support or an authorized dealer for specific options and procedures for the HSTN model.

It is recommended to store your sunglasses in the provided protective case when not in use to prevent scratches and damage. Avoid exposure to excessive heat, which can warp the frame.

Ensure the Unobtainium® nosepads are clean and free of debris. If the fit is still not secure, consider visiting an authorized Oakley dealer to explore potential adjustments or alternative nosepad options if available for this model.

Minor scratches may be difficult to remove. Avoid using abrasive cloths or cleaning solutions. For significant scratches affecting vision, lens replacement may be necessary. Contact Oakley customer support for assistance.

BiO-Matter® and O_matter materials are durable but can be affected by extreme temperatures. Ensure the sunglasses have not been exposed to excessive heat. If the material still seems compromised, contact customer support.
