The invention provides an ocular lens well corrected for aberrations through a sufficiently large angle of view and having a sufficient eye relief while ensuring avoidance of increa
An ocular zoom lens is formed of three lens groups, of positive, positive, and negative refractive power, in order from the eye-point side. The second and third lens grou
Simulated tear fluid (STF) was prepared according to the description of Zhang et al. [26] and was used with a pH of 7.4. Ocular coils were submerged in 2.5 mL STF in one well of a 12-well-plate. In order to simulate physiological tear flow conditions, we designed an in vitro lacrima...
