History of ocular straylight measurement: A review.
TL;DR: A sketch of the historical development of straylights measurement is provided, as well as the results of studies on the origins of straylight (or disability glare) in the normal eye, and on findings on cataract (surgery) and corneal conditions.

TL;DR: NINscope is presented: a light-weight miniscope with a small footprint that integrates a high-sensitivity image sensor, an inertial measurement unit and an LED driver for an external optogenetic probe that will increase access to multi-region circuit investigations during unrestrained behavior.
Simulating the straylight effects of cataracts
TL;DR: The BPM 2 filter is a good early‐cataract‐simulating filter that has a limited effect on visual acuity and contrast sensitivity, which was also found for early cataracts.

Pupil size and retinal straylight in the normal eye.
TL;DR: In normal eyes, straylight values measured with photopic pupils are by approximation also valid for mesopic and scotopic pupils, such as in night driving, and measurement of straylight under large angle and small pupil conditions can be used for quantitative assessment of eye wall translucency.

Reliability of the compensation comparison stray-light measurement method
TL;DR: The compensation comparison (CC) method is a psychophysical technique to measure retinal stray light that proves to be an efficient tool to detect unreliable measurements and may be used to decide whether to repeat a measurement.
