Eyelight

Eyelight is a decorative block that emits light.

Obtaining
Eyelight currently doesn't generate anywhere, meaning it cannot be obtained in Survival.

From Block Loot
Eyelight can be mined by hand. It drops itself.

Lighting
Eyelight has a light level of 13 (slightly lower than glowstone and similar blocks), meaning it can be used for light in builds.

Lore
Eyelight is made out of alien flesh, somehow still alive, pulsing to an invisible heartbeat. Several small pearly orbs, also flesh and likely underdeveloped eyes, will flair up on these pulses, emitting bright light.
