 A Glasstron PLM-100 | |
| Manufacturer | Sony |

| Product family | Glasstron |
| Type | Head-mounted display |
Glasstron was a series of portable head-mounted displays released by Sony, initially introduced in 1996 with the model PLM-50. The products featured two LCD screens and two earphones for video and audio respectively. The products are no longer manufactured nor supported by Sony.
The Glasstron was not the first head-mounted display by Sony, with the Visortron being a previous exhibited unit. The Sony HMZ-T1 can be considered a successor to Glasstron. The head-mounted display developed for Sony during the mid-1990s by Virtual i-o is completely unrelated to the Glasstron.
One application of this technology was in the game MechWarrior 2, which permitted users to adopt a visual perspective from inside the cockpit of the craft, using their own eyes as visual and seeing the battlefield through their craft's own cockpit.
