Dennis has to wear glasses for refractive myopia. His near point is 30 cm and lens-to-retina distance is 2.00 cm. A- If his far point is 3 m, calculate the minimum power of his eye without his glasses on. B- What is the combination optical power required to view a distant object? C- Calculate the required power of the corrective glasses if the glassed are worn close enough that Pcombo = Peye + Pglasses. D- What is the focal length of the corrective glasses? E- What if Dennis is wearing lenses that are 2 cm in
