A pair of lenses, or simply lenses, is a type of tool that appears in NetHack. It is made of glass.
The pair of lenses are the base item for The Eyes of the Overworld, the Monk quest artifact.

Generation
Pairs of lenses make up 1⁄200 (0.5%) of all tools that are randomly generated on the ground, in general shops or as death drops. Hardware stores can also stock pairs of lenses.
Description
A hero can use a pair of lenses by applying them, and can also put on or remove lenses using the associated commands. Lenses are worn on the face, and cannot be worn at the same time as a blindfold or a towel. Cursed lenses cannot be removed normally. Monsters will not use this item.
Lenses are fragile and will break if they are thrown or dropped from a great enough height (e.g. while levitating), and a force bolt spell or a zapped wand of striking will destroy any lenses in the path of the beam.
While worn, a pair of lenses has a few effects:
- Worn lenses block the blinding effect of the raven's claw attack and blinding venom from spitting attacks, though they do not prevent cream pies or other sources of blindness from affecting the hero.[1][2]
- They improve the hero's luck-based odds of finding secret doors and secret corridors when searching, if the hero is not blind.[3][4][5]
- They increase the hero's chances of successfully reading a spellbook by 10%, while reducing the time taken reading by 1⁄3.[6][7]
If the hero applies a cursed towel while wearing a non-cursed pair of lenses, they have a 1⁄3 chance of pushing those lenses off their face.[8]
The following information pertains to an upcoming version (NetHack 3.7.0). If this version is now released, please verify that the information below is still accurate, then update the page to incorporate it.
Per commit a13d6c03, a hero cannot wear lenses if they are polymorphed into a headless monster.History
The pair of lenses first appears in NetHack 3.3.0, where it is introduced alongside the Monk role, and it is adapted from a dedicated patch via commit 28975c66 and commit 53117c71. In this version, a pair of cursed lenses is considered a major trouble when successfully praying to the hero's deity—this is changed in NetHack 3.3.1.

- You push your lenses off.
- You applied a cursed towel to your face while wearing lenses, causing them to fall off.
