This refers to a specific type of lens technology found in eyewear manufactured by a well-known brand specializing in sunglasses. The lens utilizes a copper-colored base tint coupled with a silver mirrored outer coating. This combination is designed to enhance visual clarity and reduce glare in bright, sunny conditions, particularly those encountered in environments like open water.
The use of this lens type is significant for individuals engaged in activities where reducing eye strain and maximizing visual acuity are paramount. The copper tint is known for its ability to increase contrast and definition, while the silver mirror provides a high level of reflectivity, effectively blocking a substantial portion of incoming light. This design offers both functional advantages, such as improved visibility, and aesthetic appeal, contributing to the popularity of this eyewear among anglers, boaters, and those participating in other outdoor pursuits. Originally developed to provide improved sight for fisherman on the water to spot fish better but now it is a fashion symbol.
