The Index OTG (Over The Glasses) is one of the better ones on the market. It has more room inside the goggles to accommodate glasses and a wider foam area to allow more air flow to prevent fogging. It also has a cut out foam piece for the arm of glasses to fit easier. The Amber lens is good in all conditions - light enough for definition on flat light days and dark enough to cut glare on bluebirds
