Biofinity versus ProclearA comparison of the silicone hydrogel lens Biofinity and its 10 years older sibling Proclear. Both lenses are monthly replaceable contact lenses manufactured by CooperVision. While Biofinity is a silicone hydrogel lens rolled-out in 2007, Proclear was introduced in 1997 with its base material being a non-ionic hydrogel. In more detail, it is composed of a polymer of 2-hydroxy-ethylmethacrylate and 2-metacryloloyoxyethyl phosphorylcholine which is cross-linked with ethylene glycol dimethacrylate.

Biofinity provides a much higher oxygen transmissibility value due to its unique silicone hydrogel material which translates into better breathability. In fact, Biofinity's Dk/t value is one of the highest Dk/t values we have seen in any silicone hydrogel lens in the market. To keep the lens and eye moist, Proclear was implemented with a Phosphorylcholine-based technolgoy called PC Technology, while Biofinity utilizes a new technology called Aquaform to overcome the hydrophobic nature of its base material.

In looking at various online retail sources, we calculated the cost-per-day of both lenses to be very similar. While Proclear must be removed overnight, Biofinity is approved for extended wear up to 6 consecutive nights (based on your eye doctor's approval). Both lenses are tinted blue from edge to edge for visibility purposes.

Our Conclusion

Biofinity outshines Proclear on many of the crucial parameters that are indicators for good breathability, handling and end-of-day comfort. After all, Biofinity is a silicone hydrogel lens with one of the best Dk/t values that you can get today. Some contact lens wearers might still prefer Proclear as not everyone's eyes cope well with the silicone material.
