摘要：
One exemplary embodiment is a method for determining an ophthalmic prescription. An examination room is lighted to simulate daytime viewing and a conventional eye chart is used as a visual stimulus. A first corrective spherical lens power is determined by varying spherical lens power and identifying when perceived vision is best. The examination room is kept dark to simulate nighttime viewing conditions. The visual stimulus utilized is a white point source on a dark background, or a self illuminated symbol on a dark background. A second corrective spherical lens powered is determined by varying spherical lens power and identifying when perceived vision is best. An ophthalmic prescription such as one or more lenses, one or more surgical corrections or a combinations thereof is provided including a first corrective component including the first preferred spherical lens power, and a second corrective component including the second preferred spherical lens power.
