    Hyperopes also have much shorter eyeglass wearing histories and hate the thought of wearing eyeglasses during mid-life. Watch out for displaced aggression.

    The fitting and prism reference point should measure 63 with a tolerance of 0.33 Δ or 1.0 mm, depending on the power. Use a cutout chart to measure.

    The +1.50 is the old add? Distance the same? Might just be that the wearer became used to a longer work distance at near and the stronger add is blurring that distance.

    Remove your solar glasses (ISO 12312-2) so that the corona becomes visible. Do not look at the event during totality with the solar glasses or filters in place- you will see nothing.
