Research and Development

After being tasked with designing the attachment, Design Reality worked with opticians to ensure appropriate research and development of the frames, including optimising anthropometric positioning and ease of lens glazing and fitment.

Product engineering was utilised on peripheral parts to ensure a secure fitment inside the mask, consistent branding with existing Corpro products and reliable functionality for the chosen Additive Manufacture process of 3D printing.

Additive Manufacturing

The production method was chosen to benefit from rapid lead times and lower production set up costs. The nature of the Nylon substrate selected, offered high strength to allow the frames to cope with the extreme environments the product is used in.

Class 1 Certification

The frame attachment is a self-certified Class 1 medical device, which conforms to the provisions of the directive ‘Medical Devices Regulation 2017/745/EU’ and the provisions of the ‘Ophthalmic Optics – Spectacle Frames – Requirements and Test Methods ISO 12870:2018’ and subsequent amendments.
