OptiFlex FAQs

Can I wear the eyewear with other headgear like helmets or hats?

Yes, the slim and flexible design of our ULTEM-based eyewear makes it compatible with various headgear, including helmets and hats. The lightweight and thin temple arms ensure that the eyewear fits comfortably under helmets, headsets and more without causing pressure points or discomfort. 

Common points of discomfort:

What are the most common pain points of traditional eyewear that these frames solve for?

Pressure Points: Traditional eyewear can create pressure points, particularly around the temples and ears, leading to discomfort and pain during prolonged use.
Headaches: The pressure exerted by both the headset and the eyewear can cause headaches due to poor fit and additional weight on the head.
Ear Pain: Eyewear frames that are not designed to be worn with headsets can press against the ears, causing pain and discomfort.
Slipping: Normal eyewear might slip down the nose due to the added weight and movement from the headset or other devices, requiring frequent adjustments.
Marks and Indentations: Wearing regular eyewear under a tight headset can leave marks or indentations on the skin where the frame presses against the head.
Reduced Comfort: Overall comfort can be significantly reduced, making it difficult to wear the headset and glasses for extended periods.
Distorted Fit: The pressure from the headset can distort the fit of traditional eyewear, making it sit unevenly or uncomfortably on the face.

Additionally, the flexibility of ULTEM allows the eyewear to adapt to different shapes and sizes of headgear, ensuring a secure and comfortable fit. This makes our eyewear ideal for activities requiring additional head protection, such as cycling, motorcycling, and industrial work. It is also well-suited for use in production environments and aviation, where headgear is commonly worn. The durable nature of ULTEM ensures that the eyewear can withstand the rigorous conditions often encountered in these settings while providing the comfort and protection you need.

Can I adjust my ULTEM-based eyewear for a better fit

No, our ULTEM-based eyewear frames are designed with fixed temples that cannot be adjusted. This design ensures durability and stability, maintaining the structural integrity of the frames. Our eyewear is engineered to fit a wide range of head sizes comfortably without the need for adjustments, thanks to the inherent flexibility of the ULTEM material. For any concerns about fit, we recommend consulting an optician or contacting our customer service team.

How durable is your eyewear?

ULTEM is known for its exceptional durability. It is resistant to impact, heat, and chemicals, ensuring long-lasting performance even under rigorous conditions

 Does the ULTEM material contain any allergens?

 No, ULTEM is hypoallergenic. While some components of our eyewear may be constructed from materials that could contain allergens, all parts that come into direct contact with your skin are made from ULTEM, which does not contain common allergens like latex or nickel,
ensuring it is safe for individuals with sensitive skin or allergies.

 How much does your ULTEM-based eyewear weigh?

Our eyewear is incredibly lightweight, weighing on average 20 grams. This ensures maximum comfort, especially for prolonged use under a headset or in any environment. Please note that the final total weight of the eyewear may fluctuate depending on the lens type and
prescription.

What is the best way to clean and maintain the eyewear?

The frame can be wiped down with a damp cloth. Avoid using harsh chemicals or abrasive materials. While ULTEM is chemically resistant, harsh chemicals can damage any surface coatings or finishes on the eyewear. We recommend using mild solutions to ensure the longevity and appearance of your frames. Our lenses can be cleaned like any other glasses, using a lens cleaning spray and cloth. If you’re looking for a great lens cleaning kit, we recommend our Wash & Dry kit which comes with an isopropyl alcohol spray and mini microfiber cloth. For quick cleaning convenience, we also have pre-moistened wipes with a new and improved ammonia-free solution that removes smudges and dirt without leaving residue.
