Yup could be allergic contact dermatitis. It may result from chemical in the air or direct contact with your skin. Where exactly u work, it might be related to your work. Do they itch..? Nickel is considered as most common causative agent for ACD, remember if u have allergy to nickel ( batteries). Try to avoid dust and rust as possible, wear some protective stuffs ( hats, Sunglasses)..if its severe and itchy u may get anti-itch creams and low potent steroids cream...(try to avoid steroid cream around eyes)
