Vancouver, British Columbia--(Newsfile Corp. - April 20, 2026) - Rise Nano Optics Ltd. (CSE: EYE) ("Rise" or the "Company"), a health technology company advancing vision care through patented nanotechnology lens solutions, today announced a strategic partnership with Sierra Optical Lab ("Sierra Optical"), an independent wholesale optical laboratory and VSP®-Authorized Lab, located in Reno, Nevada, to support the production and commercialization of its SPECTRAGUARD™ lens technology in the Western United States region.

The Company's proprietary SPECTRAGUARD™ technology is a patented nano particle optical lens treatment that provides a new standard of eye protection for the general eyewear market while meeting the needs of those with degenerative eye disease. The patented technology is designed to provide eye protection from bright sunlight by filtering 100% of ultraviolet (UV) light and up to 90% of wavelengths between 400-600 nm, including blue light, while preserving natural visual clarity and color perception.

This partnership establishes a robust model, combining direct commercial demand generation by Rise, with integrated manufacturing and distribution through Sierra Optical, allowing for efficient scaling without significant capital investment in production infrastructure.

Under the partnership, Sierra Optical will:

• Manufacture SPECTRAGUARD™ lenses on behalf of Rise

• Distribute SPECTRAGUARD™ lenses through its existing network of eye care professionals (ECPs)

• Support fulfillment of Rise-generated demand, enabling scalable production as the Company expands its commercial footprint

Erik Ritchie, Chief Commercial Officer of Rise Nano Optics, commented,"This partnership is an exciting first step in our US commercialization strategy. By aligning with a state-of-the-art VSP®-authorized lab that can both produce and distribute, we are creating an efficient path to market while positioning the Company to scale quickly as demand builds. As previously mentioned, this partnership is the first step in our commercialization strategy which also includes clinical channel partnerships, followed by broader consumer and brand integration, delievering meaningful revenue generation. The global eyewear market size is approximately US$160B¹ with strong relevance to individuals affected by prolonged screen exposure, light sensitivity, and degenerative eye conditions, so there is significant upside potential for us to capitalize on demand for technologies like ours."

Steven Mullen, Co-Founder of Sierra Optical Lab, commented, "We are pleased to partner with Rise Nano Optics to bring SPECTRAGUARD™ lenses to our customers and optical network. Their proprietary technology is a first mover and introduces a differentiated approach to lens performance, addressing modern visual demands while maintaining clarity and color accuracy."

This is the Company's first optical lab partnership and represents a key milestone in its commercialization strategy in the United States. The Company intends to replicate this model by aligning with additional independent and authorized laboratories, creating a distributed manufacturing and fulfillment ecosystem capable of supporting increasing demand as adoption of SPECTRAGUARD™ lenses grows. By leveraging established lab infrastructure and industry relationships, Rise is positioned to scale efficiently without significant capital investment, while maintaining flexibility across multiple distribution channels.

As part of its global strategy, Rise will continue to establish a network of optical lab partners, clinical channel partnerships as well as broader brand integrations across North America and internationally.
