Biofinity Energys vs. Bausch + Lomb ULTRA
A comparison of Biofinity Energys from CooperVision and Bausch + Lomb ULTRA. What are the differences?
CooperVision and Bausch & Lomb added these monthly replaceable lenses to their product portfolios in 2016 and 2014, so we are looking at two fairly new lenses. Biofinity Energys is the successor of the popular Biofinity lens and you can read about the differences between these two lenses in our direct comparison. Biofinity Energys is a Comfilcon A lens, a silicone hydrogel material with a 48% water content, while the Bausch+Lomb ULTRA lens is built with non-ionic polymers and a PVP wetting agent, holding 46% water. The breathability, measured using the oxygen transmission parameter is 160Dk/t and 163Dk/t, some of the highest in the industry. CooperVision's Energys lens doesn't use any additional wetting agent and can be worn up to an extended period of seven days (based on your eye doctor's recommendation), while the ULTRA has to be taken out at the end of the day. As prices are quite similar, it really comes down to personal preference and how your eyes might react to the material.
