To compare the effect of interrupting positive vs negative lens wear, the percentage relative change (the ratio between the relative change in the interruption group and the control group) was calculated, and unpaired two-tailed Student’s t-tests were used to compare normal vision vs dark ...
模具以及使用该模具形成正或负透镜的方法 Molds and methods of using the mold to form a positive or negative lens本发明分别包含铸造透镜的一种方法和装置,其中优选由塑料形成的两个模具(20)和(40)通过一个环(50)被互相连接或者结合在一起,形成一个模腔(60),所述模腔的尺寸与要在其中形成的透镜的尺寸...
Based on correlated imaging with pseudo-thermal light, Wu and Meyers independently experimentally showed that both positive and negative images can be obtained by using a novel algorithm. With the theory of statistical optics, we construct the model of thermal light, and demonstrate the novel algorit...

The positive first group of lenses (11) and the negative second group of lenses (12) are variably spaced apart for altering the focal distance and which are positioned in a series from the object side. The first lens group has a negative first lens element. A plastic second lens element ...
Like negative body image, researchers have examined demographic differences in positive body image. Much of this work has focused on the body appreciation component, drawing on the widely used and well-validated Body Appreciation Scale (both the original and second versions of the measure; Avalos et...
The system has a first positive lens group, and a second negative lens group, arranged in sequence and observable from the object side. A central or rear part of the positive first lens group (11) is formed as a sharp adjustment lens group (11F), which is movable along the optical ...
alenses (Winawer and Wallman, 2002). In the extreme case, if negative lenses are worn all day long except for four 2 min episodes of positive lens-wear, the eyes compensate in the direction of the positive lenses (Zh[translate]
Positive affect is measured using the 10 positive affect items on the Positive and Negative Affect Schedule (PANAS) [59]. HRQoL is assessed via the well-validated Medical Outcomes Study Short Form-12 (SF-12) [58], which has been associated with mortality in cardiac patients. Anxiety and ...
