The Optoplast Actman Eyewear Company celebrated its 70th anniversary at the Sky Garden, an exclusive venue in London, on Oct. 6. To celebrate the landmark, the British eyewear maker launched four limited edition Walter & Herbert styles. The frames are available for men and women, with one optical and one sun design, and the company is offering only 100 of each of the frames, which are presented in a special wooden box. The new styles, inspired by the brand's core Made in England theme, are named after the historic figures of Constable, Chaucer, Woolf and Nesbit. The Walbert & Herbert brand is named after Optoplast's founders, Walter Conway and Herbert Thorn. On the occasion of the anniversary event, Optoplast also presented a cheque of £2,100 (€2,330.5-$2,560.3) to Momentum, a children's cancer charity. Since the beginning of the year, the company has been making a donation for every pair of frames sold from its 2016 Walter & Herbert range.
