With the spectral goggles, a see-through photopic transmission rate of 75% can be achieved, with the possibility to block unwanted rays coming from laser pointers at 532 nm.
Caption: Figure 2 A waveform produced by the ISCEV standard photopic 3 ERG in a normal patient: 1 indicates the crest of the a-wave trough; 2 indicates the crest of the b-wave peak; 3 indicates the baseline ERG measurement; and 4 indicates the second of two small ripples on the rising edge of the b-wave, known as oscillatory potentials.

Five studies [Berman and others, 1990; Houser and others, 2004; Houser and others, 2009; Royer and Houser 2012; Vrabel and others, 1998] using a discrimination procedure to investigate spatial brightness under lighting of different SPD at photopic levels meet these criteria and are therefore considered to provide reliable evidence of lamp spectrum effects.
The aesthetics of cool fluorescents at nighttime are suboptimal, and while the energy savings potential of so-called scotopic lighting is demonstrable, lighting designers must currently still design to IESNA-established lighting criteria and recommendations, which are all based on the photopic luminous efficiency function V(lambda) (IESNA 2010, U.
Walks on the courses were made under two illumination conditions: photopic and mesopic.
It causes significant thinning of the outer plexiform layer, lowering of the horizontal cell count, and significant reduction in amplitude of photopic and scotopic electroretinographies.
It has been demonstrated that the transition from scotopic to photopic vision occurs at an illuminance of 7.

It depends among other things on target size and ambient light level, decreasing with increase of light level, but leveling off and hardly changing in the photopic domain.
