In this study, reaction time in real mountain weather conditions was tested when participants wore different ski goggles lenses, which all let in a different amount of light (a measurement also called visible light transmission (VLT)). Different ski goggle lenses all have different amounts of VLT, and high VLT is usually best for dark days, to let the most light in your eyes, and a low VLT is usually best for a sunny day (sometimes also referred to as a “bluebird day”) where you don't want to let as much light into your eyes (SkatePro.com). Through this study, it was found that there are no massive differences in lenses, but there is some significant data. The data backs up the claim that reaction time is hurt when a sub-optimal lens is used, but not by a large amount.
The goal of this research is to raise awareness on the importance of bringing different lenses while skiing in order to always have the ability to wear the correct lens for the condition. Proving that ski goggle lenses have a large effect on reaction time will help prove the importance of bringing different lenses and cutting down on injuries. If the findings do not conclude that ski goggle lenses have large effects on reaction time, then it will make people more aware that ski goggles might not be as important as people think for cutting down on injury, and we can focus our energy on other skiing factors, such as ski bindings, helmets, etc.
