Achromatic Lens
by Killerkrow
Achromatic Lens adds 23 craftable lenses to Minecraft 1.20.1 that change the game's rendering through a shader on each lens.
What it does
Each lens is crafted from a Spyglass and a Base Lens blueprint, and every lens applies a different shader while it is held. The mod ships with 23 lenses in total, including a range of blur levels such as Slightly Blurred Lens, Roughly Blurred Lens and Semi Blurry Lens, alongside an Old Lens. Switching shaders is done by choosing the lens, and the list of working shaders is described in the author's notes.
Achromatic Lens runs on the client and the server, so the server and every player need the mod. It is built for Fabric and targets only 1.20.1, with version 1.0.1 as the latest file dated 2026-06-24. The mod is released under All rights reserved and is not open source, although the source code and issue tracker are publicly linked. No required dependency is listed for Fabric.
