Spectacles are an accessory that improves the Spelunker's vision. They can be bought from certain shops, occasionally found in crates or received as a gift from Kali after making enough sacrifices at one of her altars. Spectacles are rarely considered to be worth buying from shops due to the functional overlap with the Udjat Eye, which is gained for free and is guaranteed to appear. They are not completely worthless however, as they do indeed have a useful advantage over the Udjat Eye.
