MyDay vs Clariti 1 Day: Which CooperVision Daily Lens Has Better Oxygen Performance?
CooperVision's two daily silicone hydrogel lenses share Aquaform® Technology but differ in material, oxygen transmissibility, and price. For wearers prioritizing oxygen performance, here is a precise comparison.
| Feature | MyDay | Clariti 1 Day |
|---|---|---|
| Material | Stenfilcon A | Somofilcon A |
| Dk/t | 100 | 86 | Water Content | 54% | 56% |
| Aquaform® Technology | Yes | Yes |
| UV Protection | Class 2 (~85% UVA / ~96% UVB) | Class 2 |
| Toric Version | MyDay Toric | Clariti 1 Day Toric |
| Price Point | Higher | More accessible |
Why the Dk/t Difference Matters
MyDay's Dk/t of 100 represents approximately 16% higher oxygen transmissibility than Clariti 1 Day's Dk/t of 86. For the majority of daily lens wearers, both levels are sufficient for healthy daily wear of up to 16 hours. The clinically meaningful difference arises for wearers with a history of corneal hypoxia, those who regularly extend wear beyond 12 hours, or those transitioning from high-Dk/t monthly lenses.
- • Choose MyDay if oxygen transmissibility is a priority, or you wear lenses for long daily periods
- • Choose Clariti 1 Day for CooperVision Aquaform® comfort at a more accessible price, when elevated Dk/t is not specifically required
Both lenses require a valid prescription. Your eye care professional can advise on the best choice for your ocular health needs.
