Which lens goes into a prescription safety frame?

A safety frame is only as safe as the lens in it. Ordinary plastic (CR-39) and glass lenses can break into sharp pieces, so we never fit them in a safety frame. We glaze every pair ourselves in Abu Dhabi, following international safety-eyewear practice, and choose the lens by your prescription strength:

• Polycarbonate (standard) — the industry-standard safety lens: highly impact-resistant, light, and blocks 100% of UV. Fitted as standard for prescriptions up to ±6.00.
• 1.60 MR-8 photochromic grey — for people who move between indoors and the sun: clear inside, darkens to around 50% outdoors. 100% UV protection.
• Polycarbonate Transitions Gen S — the fastest light-adaptive lens in a polycarbonate material; up to 70% dark in sunlight, clear indoors.
• 1.67 high index — recommended where polycarbonate or MR-8 is not feasible for the prescription, typically above ±6.00. High-index material is denser, and the lens thickness at these powers contributes to its strength. 100% UV protection, available clear, photochromic grey or with Transitions Gen S.

All of these lenses block 100% of UV as standard. Prescriptions above ±9.00 are handled personally — send us your prescription on WhatsApp.

Frequently asked questions

Why can’t my normal lenses go into a safety frame?
Standard CR-39 plastic and glass lenses can shatter into sharp pieces. Safety frames are glazed only with impact-rated materials — polycarbonate as standard, or 1.67 high index where polycarbonate is not feasible for the prescription. We fit them ourselves in Abu Dhabi.

Do the lenses block UV?
Yes. Polycarbonate, MR-8 and high-index lenses block 100% of UV as standard, clear or photochromic.

Can I have lenses that darken outdoors?
Yes — choose Photochromic in the lens selector: 1.60 MR-8 grey (up to about 50% dark) or polycarbonate Transitions Gen S (up to 70% dark, faster). Both are impact-rated and block 100% of UV.

Can you fit progressive or bifocal safety lenses?
Yes — message us on WhatsApp with your prescription; progressive safety lenses are quoted by hand so we can confirm the fitting height on this frame.

Do you supply company or bulk PPE orders?
Yes. Send us the list of names and prescriptions on WhatsApp and we will quote the batch, including home try-on of sample sizes in Dubai or Abu Dhabi.

I’m not sure what size is right for me. How can I make sure I get the right size?
Use our home try-on service in Dubai and Abu Dhabi, or send us a photo wearing your current glasses, or the measurements printed inside their temple arm, on WhatsApp. Visiting Abu Dhabi? We will fit it in person at the store.

Do you deliver to Dubai?
