Best photochromic progressive eyeglasses

Start here: the touk Photochromic Progressive Multifocal. It's the most complete everyday pair in this set — three lens zones (distance up top, computer in the middle, close reading at the bottom) plus lenses that darken outdoors and clear indoors. That's the combination most people actually want for all-day wear.

Who the others suit:

• Cyxus Progressive Photochromic — a lighter, rimless metal frame if you want something barely-there.
• Photochromic Progressive with Blue Light Filter (Selzari) — if you're at a screen most of the day and want blue-light filtering too.
• Ultra-Light TR90 Multifocal (Charmoo) — the pick if weight is your main worry; it ships from overseas, so allow extra time.
• Ray-Ban RB5435 Optics Change — the one to choose if you'd rather have a branded frame and a proper optical look than a budget reader.

Two things worth knowing before you buy: most of these are fixed-magnification readers rather than lenses made to your prescription, and the cheap ones vary a lot in frame quality — check the ratings on each card.
