The Developmental Process of Blur Circle along to the Variation of a Refractive Power for Hyperopia

원시에서 교정굴절력변화에 따른 착란원 크기

A variable process of blur circle is calculated for a artificial hyperopia. The calculation is used to the value of Gullstrand's theoretical eye and a method of geometrical optics. The theoretical eye simplified a entrance pupil and the retina. Ophthalmic lens and eye changed a equivalent lens. Refractive power of a equivalent lens is converted to focal length within theoretical eye, and this is calculated about relation of a blur circle on the retina and ophthalmic lens.
