Supported by our customers over the years and evolving with their needs and changing times, Midori Safety’s protective eyewear has been developed with the concept of ‘gently protecting the eyes’. Focusing on ‘safety,’ ‘functionality,’ ‘comfort,’ and ‘design’ as four main pillars, we have enriched our product offerings. We will continue to deliver safety to our customers with the trusted ‘Vision Verde’, ‘LUNE VERDE’, and ‘UVEX’ brands.
