Nimbus Dark Category 4 Sunglasses

New product



UK brand Rapid Eyewear have been manufacturing their range of specialised sunglasses for over twelve years. Based on the ever-popular Nimbus wrap-around sports frame, 'Nimbus Dark' adds a category 4 lens which is the darkest tint available under the standards of ISO 12312. A category 4 lens is perfect for use in extreme sun conditions, including at altitude, whilst being ideal for those who suffer from light sensitivity (photophobia) problems.

The Frames

Made from a robust yet lightweight TR90 composite, the frames are finished in an attractive matt black colour. They feature sprung side arms and rubber side arm extensions for an ultra comfortable fit. The Nimbus frame is designed to fit most adults; a slight built-in flex means the frame will 'mould' itself to your head comfortably. The wrap-around sports shape prevents light intrusion from the sides of your vision.

The Lenses

Nimbus has lenses cut from an impact-resistant polycarbonate material. Each lens is decentred, to calibrate the field of view such that the slight curvature does not distort your vision. 

Pouch & Accessories

A microfibre pouch is supplied, that doubles as a cleaning cloth. if you would like a retainer strap, please select this option from the menu at the top of this page before completing your purchase. A wide range of additional lenses are available for this frame - to view these, please click here.


Nimbus sunglasses comply with all aspects of ISO 12311 and ISO 12312 standards. 

Important Note: Driving
Please note that category 4 sunglasses are NOT suitable for driving, cycling, motorbiking or any other road use. They are designated as dangerous for use on the road according to ISO 12312 standards. Please note there are numerous category 4 products for sale on Amazon that claim to be suitable for driving - some are even marketed as being 'driving sunglasses.' USING CATEGORY 4 SUNGLASSES FOR DRIVING IS EXTREMELY DANGEROUS and should be avoided at all costs.
