MyDay and MyDay Energys are both daily disposable contact lenses from CooperVision, which means that you throw them away at the end of the day and use a fresh pair the next day. MyDay has been around since 2015, while MyDay Energys was released in March 2023. The newer MyDay Energys lens is designed to be an upgrade to the MyDay lens, with new technology that aims to enhance vision and comfort. There are some differences in the prescription parameters between the two lenses. MyDay Energys has a wider range of sphere powers, which means it can accommodate a greater range of prescriptions. This is good news for people with stronger or prescriptions who may have had trouble finding comfortable contact lenses in the past. In terms of features, both lenses have the same base curve, diameter, lens material, water content, center thickness, oxygen transmission, and UV blocking. However, MyDay Energys has a few extra features, including Aspheric DigitalBoost™ design and AquaForm Technology. These are designed to help enhance visual performance and comfort, especially for people who spend a lot of time looking at screens. Finally, the packaging and pricing of the two lenses are different. MyDay comes in boxes of 30 or 90 lenses, whereas MyDay Energys comes in boxes of 90 lenses. MyDay Energys is a bit more expensive per day than MyDay, but it may be worth the extra cost if you're looking for advanced features and enhanced comfort.
