What is the focal length of the contacts

Reference no: EM13540874

A nearsighted person cannot read a sign that is more than 6.0 m from his eyes. To deal with this problem, he wears contact lenses that do not correct his vision completely, but do allow him to read signs located up to distances of 14.1 m from his eyes. What is the focal length of the contacts?
