I’ve used high index lenses for a long time to help reduce the thickness and weight of my glasses. One drawback to high-index is increased chromatic aberration, so I actually get a high-ish index but not the highest my optician offers.
Don’t choose frames with oversized lenses. The wider/taller the lens is, the thicker it will be at the edges. Choose frames with some bulk around the edges. Plastic frames hide far more of the thickness than wireframe and rimless.
And if you can afford it: anti-reflective coating and polished edges help lighten the looks of thicker lenses.
