About These Lenses: Yellow is one of our favorite colors because it is such a cheerful happy color. Yellow is also a very alert color, and you will probably notice you have an increased attention to detail. This makes sense because Yellow lenses are known to increase visual acuity, which is why sharp shooters often wear Yellow lenses. With increased alertness and focus you will find yourself more motivated throughout the day and getting more done, and feeling cheerful while you're doing it.
