I will only use Zeiss Dark Umbral lenses set in very thin frames with thin side-wings so they don't get pressed into my temples by the headsset.
The lenses are optical glass and therefore rather soft. Any good frames can be used. Most optometrists can order a set of lenses and set them in a frame. Expect $300-330 Aust for the job. Buy a good case to keep them in when not wearing them. A neck-strap is also helpful.
