We calculate stress distribution on the surface of a spherical cell trapped by two counter-propagating beams in an optical stretcher in the ray optics regime. We explain the apparition of peaks in the stress distribution, which were not revealed in the earlier published results. We consider the divergence of the incident beams from the fibers, and express the stress distribution as a function of fiber-to-cell distance. In an appendix, we show that the local scattering stress is perpendicular to the spherical refractive surface regardless of incident angle, polarization, the reflectance and transmittance at the surface. Our results may serve as a guideline for the optimization of experimental parameters in optical stretchers.
