高折射率漸進透明變色處方鏡片

The transition from clear to dark grey is so quick that I barely notice the change when I walk outside. These are noticeably thinner than my old lenses, even with my strong prescription.

I've worn progressives for years but these high index ones are noticeably thinner, so my strong prescription doesn't look like coke bottles anymore. The transition to dark grey outside is quick and they go fully clear again once I'm indoors.

I was worried progressives would feel heavy on my nose, but these high index ones are noticeably thinner than my last pair. They go dark grey pretty quickly in sunlight and clear up again once I'm inside, which is exactly what I wanted for driving.
