A system for determining a spherical power of the eyes of the subject based on the measured refractive error associated with the red reflex image is provided. The system (i) predicts a position of a plurality of facial landmarks on the facial image of the subject, (ii) extracts the eyes...
Define spherical. spherical synonyms, spherical pronunciation, spherical translation, English dictionary definition of spherical. also spher·ic adj. 1. a. Having the shape of a sphere; globular. b. Having a shape approximating that of a sphere. 2. Of or
A spherical power whose focal point coincides with the circle of least confusion of a spherocylindrical lens. Hence, the spherical equivalent of a prescription is equal to the algebraic sum of the value of the sphere and half the cylindrical value, i.e. sphere + cylinder/2.Example: the sphe...

We Eye 1246 Measuring spherical aberration using ray tracing-type aberrometer I Jun et al Figure 1 (a) Internal SA of group 1 at 5-mm pupil size, according to IOL power. (b) Internal SA of group 2 at 6- and 5-mm pupil size (highlighted line: À 0.2 mm, designed value of IQ...
In all these studies, the participants were of similar age, the duration of a single intervention was the same (3 minutes), and the power of the laser entering the pupil was the same (0.29 mW). In a study by Jiang et al,1 the median compliance was 75%, and 14.2%...
I brought all logic to bear, I put out of mind the excitement of our position in watery space and tried to think sanely of comparative colors and I failed completely … the blueness of the blue both inside and outside our sphere seemed to pass materially through the eye into our very be...
