Phoropter

The phoropter is a constructible settlement item added in the Fallout 4 add-on Vault-Tec Workshop.

Characteristics
One of the items added in Vault-Tec Workshop, assigning a settler to the Photopter will generate 5-15 happiness for the settlement. The amount of happiness generated, crafting and power requirements for this item depend on the choices made during the Vision of the Future quest.

The "Subliminal Messaging" option will produce a version that produces 15 happiness and requires 6 power, but has a mortality chance of 2. The "Vault Monitoring" option will produce a version that produces 5 happiness and requires 3 power, with a mortality chance of 1. The "Improved Eye Care" option will produce a version that produces 10 happiness and requires 3 power.

All three versions improve the Sole Survivor's Perception by 1 after use. This effect lasts until another of the Vault-Tec Workshop exercise equipment items is used.

Crafting
