The Costa 400 sunglasses use polycarbonate lenses, molded plastic stems and nose bridge and metal hinges. These sunglasses are designed for outdoor use and include a polarized lens version marketed for fishing and water sports. Sunglasses are often subjected to extreme outdoor conditions that compromise their function. When this occurs, the sunglasses need to be repaired. The Costa 400 sunglasses are no different than many other sunglasses in the repairs. If the lenses are scratched or damaged, do not use them as this may lead to eye injury. Contact Costa about warranty replacements on scratched or damaged lenses.
Things You'll Need
- Dust free chamois
- Lens cleaner
- Small optical screwdriver
- Heat gun
- Replacement stem hinges
Tighten the small screws at the top of the stems at the hinge if the stems are loose or out of position. Tighten until firm but not to the point the stems will not fold into the frames.
Unscrew all screws from the stem hinge and remove the hinge. Unscrew the hinges over a bench or white piece of paper in case they fall, as it is easy to spot the hinge against a white background. Wipe off the hinge area and place the new hinge onto the holes and screw into position. Place the stem into the hinge, add the screw and tighten.
Hold the stem if it is bent, under a heat gun for a few seconds. Gently bend the stem back into position. Apply more heat as the stem cools to continue the bend. Stop bending when your desired position is reached.
Pour the lens cleaner onto the chamois cloth and wipe down the lenses. Use a dry chamois to remove the fluid and clean the lens.
