Since the index of refraction of the tear layer and the cornea are very similar, you now have a regular optical surface in place of an irregular one If the curvature of a contact lens is not the same as the cornea (as may be necessary with some individuals to obtain a comfortable fit), the tear layer between the contact and cornea acts as a lensA multifocal lens having a center optical zone for creating a first focal point within 2° of the optical axis and a peripheral optical zone located adjacent the center optical zone for creating a second focal point from 2° to 10° of the optical axis, the peripheral optical zone having a correction of at least 2 diopters more than the center optical zoneThe aim of the study was to investigate the prevalence of induced prismatic effects due to poorly fitting spectacle frames A sample of 100 spectacle wearing subjects was selected as participants

The highest magnifying power is obtained by putting the lens very close to the eye and moving both the eye and the lens together to obtain the best focus When the lens is used this way, the magnifying power can be found with the following equation MP0 = 1 4 ⋅Φ1 MP 0 = 1 4 ⋅ Φ 1 where Φ Φ = optical powerI Transposition 1 Change the axis by 90 degrees 2 Change the sign of the cylinder 3 Combine the sphere with the cylinder II Spherical Equivalent 1 Combine ½ of the cylinder power to the sphere 2 Drop the axis III Reading Prescription EXAMPLE Rx 100 0 x 180 1 Change the axis by 90 degrees =90 2Opticians design and fit eyewear, this includes spectacles, contact lenses, low vision aids and other specialized optical devices We interpret the prescription from the eye doctor and determine the best way to fill it Every pair of glasses or contact lenses is custom designed for that patient's specific needs We are also fashion consultants
