If you have trouble seeing this area, use a magnifying glass and more lighting.

Ending3: [title] Take them off, with the sunglasses turned so that you can see the shape of the lenses. [step] If they are too long, turn the frames off, still with the sunglasses on. Ending4: [title] Take off the protective eyewear and test your lenses. [step] If you are comfortable with the way it looks, you may be able to remove them without any frustration.
