  1. If a person wears glasses, how do the masks seal around the temples of the glasses? I have always wondered about this problem.

  2. Alan,

    Troops using military gas masks cannot wear standard eyeglasses. Military masks have special inserts that hold corrective lenses inside of the eye ports. Troops needing glasses have to be specially examined and inserts made specifically for them. You cannot wear contacts. I never needed inserts, but my oldest daughter does and she hates them. However, given the alternatives, she tolerates them. I need glasses for reading now, but I can manage without them when wearing my current mask as part of my prep supplies.
