Great eyewear should feel like a natural extension of your expression from the first moment you put it on. The Zirosat 18131 pairs a poised full-rim round silhouette with finely finished featherlight tr90 polymer construction, giving the face crisp definition. Its calibrated 51 mm x 50 mm lens aperture frames the eyes with balanced proportion for single-vision, progressive, or blue-light lenses.
Across its 144 mm front width, a sculpted 19 mm bridge works with 150 mm contoured temples to prevent slippage. Offered in curated finishes โ C5, C6, C4, C3 โ the 18131 brings bespoke optical distinction to daily wear.
Exact factory dimensions: 144 mm total frame width, 51 mm lens width, 50 mm lens height, 19 mm bridge, and 150 mm temples.
Selecting the right optical frame is an investment in visual clarity and everyday confidence. If you need help comparing the 144 mm width or 51x50 mm lens profile of the Zirosat 18131 against your current glasses, or want advice on lens options, email info@fuzweb.com or call +1 (778) 860-5467.

Updated ยท August 8, 2026From the moment you place your order to the moment it is delivered, United States:
This is the complete window, lens making and shipping included โ not just the shipping part. Ready-made frames without prescription lenses land at the short end of the range; prescription and custom lenses at the long end.
The window above is made of two parts. Making your glasses comes first, shipping second.
Add the two parts and you get the window at the top: ready-made frames 6 to 14 business days, prescription lenses 12 to 18 business days. Orders placed on a Saturday, Sunday or a public holiday start the next working day, which adds one.
Business days in transit after your order leaves us. Add the making time above to get the full window.
We may adjust these windows at any time without notice.
