Desmond's eyeglasses

Desmond's eyeglasses are a piece of headwear in the Fallout 3 add-on Point Lookout, worn by Desmond.

Characteristics
They provide a damage resistance of 1 as well as bonuses of +5 to Explosives and Small Guns skills. They can be repaired with glasses, Doctor Li's glasses and Three Dog's glasses.

Desmond will disappear from the game when A Meeting of the Minds is completed, so you must pickpocket or kill him before then to get the glasses. His glasses have a high item health, so a high level piece of headwear that covers the eyes must be placed in his inventory to pick the glasses.
