It’s estimated that more than 100 million birds are killed every year due to collisions with glass surfaces, and now German company Glaswerke Arnold has come up with a possible solution by coming up with glass that appears normal to humans but is very visible to birds. They used the principle that birds have the ability to see light in the ultraviolet spectrum, and thus the company developed the glass with a patterned UV-reflective coating that makes it visible to birds while remaining transparent to the human eye. The glass was initially introduced back in 2006, but the company has updated it to an improved version with a crisscross pattern. When tested in Germany, it was reported that it reduced the incidents of birds striking the glass by up to 75 percent.
