An item purchasable in QFG2: Trial By Fire at Keapon's Magic Shop.
Background[]
They can be worn by the hero (with no visible changes to his appearance). The effect is described as making everything appear veiled but they don't make any apparent change to the display. However, there is one point in the game where they do have an effect. While Zayishah is getting changed, if the character is wearing the glasses, the veil concealing her will be transparent and she will be visibly naked (within the limitations of EGA graphics).
Behind the scenes[]
Despite the common misbelief, wearing the glasses at this point in the game will neither reduce Paladin Points and Honor nor prevent the character from becoming a Paladin.
