Quizplus · Accepted Answer

The uncorrected near point is the distance at which the person can see clearly without any correction. The power of the contact lenses is +3.33 diopters, which means that they converge light by 3.33 diopters. The near point of the person with the contact lenses is 25 cm, which means that the object is 25 cm from the eye. The uncorrected near point is the distance at which the person can see clearly without any correction, which is 1.5 m.
