1. CONDUCT PRE-DEPLOYMENT THREAT ASSESSMENT: Confirm the operational environment presents no ballistic, fragmentation, or significant impact hazard. If any such threat exists, set these sunglasses aside and select APEL-approved ballistic eye protection rated to the appropriate standard.

2. IDENTIFY THE PRIMARY VISUAL HAZARD: Verify that solar glare or intense ambient light is the primary impediment to visual performance before proceeding. These sunglasses are a glare-reduction tool, not a general-purpose protective eyewear solution.

3. RETRIEVE AND OPEN THE PROTECTIVE CASE: Remove the carrying case from its storage location, whether a uniform pocket, gear bag, or vehicle compartment. Open the case fully before extracting the eyewear.

4. EXTRACT EYEWEAR WITHOUT LENS CONTACT: Grasp the eyewear by the metal frame bridge or temple arms only. Do not contact the lens surfaces directly, as skin oils will smudge the acrylic and degrade optical clarity.

5. PERFORM PRE-USE INSPECTION: Examine both lenses for cracks, deep scratches, or delamination that would impair the field of view. Confirm frame integrity at the hinge points, verify nose pads are firmly attached, and check that hinge screws are secure.

6. DON THE EYEWEAR WITH BOTH HANDS: Using both hands, slide the temple arms over and behind the ears simultaneously. Settle the nose pads onto the bridge of the nose and adjust for a level, secure fit that provides maximum lens coverage.

7. MONITOR LIGHT CONDITIONS DURING USE: Remain aware of transitions from bright to low-light environments throughout the operation. The smoke tint significantly reduces light transmission, and continuing to wear these sunglasses in darkened conditions will severely impair vision.

8. DOFF IMMEDIATELY UPON ENTERING LOW-LIGHT ENVIRONMENTS: Grasp both temple arms simultaneously and pull forward and away from the head. Do not attempt to transition through buildings, tunnels, or shadowed terrain while wearing these sunglasses.

9. CLEAN LENSES BEFORE STOWAGE IF CONTAMINATED: Blow loose debris off the lenses or rinse with clean water before wiping. Apply an approved lens cleaning solution or mild soap and water, then wipe dry with a clean lint-free microfiber cloth only. Paper towels, shirt fabric, and abrasive materials will permanently scratch the acrylic surface.

10. STOW AND SECURE THE EYEWEAR: Place the eyewear fully seated into its protective case and close the case completely. Return the case to a designated storage location away from extreme heat, crushing hazards, and chemical exposure including DEET-based insect repellents and petroleum products.
