The company states that Rubin's Ruler, which has been designed by US-based optician Bruce Rubin, is the first of its kind to serve different purposes. It claims that its Accu-Slide height gauge offers exact calculation of seg heights and other vertical measurements, offering a greater reading accuracy. The device also allows the scales to be read in different positions. - Hilco has introduced two products for cleaning anti-reflective coated lenses. Its range of Pre-Moistened Towlettes clean without streaking, says the company, and are supplied in a single-feed box. Hilco has also redesigned the packaging for its Crystal Cleaner Formula, which is available in 118ml sizes and in a 12-bottle display.
