The effects of ambient narrowband long-wavelength light on lens-induced myopia and form-deprivation myopia in tree shrews
2023, Experimental Eye ResearchLimited bandwidth short-wavelength light produces slowly-developing myopia in tree shrews similar to human juvenile-onset myopia
2023, Vision ResearchCitation Excerpt :Tree shrews are small diurnal mammals that are very closely related to primates (Janecka et al., 2007). Like most mammals, tree shrews are dichromats, with short and long wavelength sensitive cone types (Petry & Hárosi, 1990). Most (not all) humans are trichromatic, with short, medium, and long wavelength sensitive cones - but there is evidence that, as regards emmetropization, humans are functionally dichromatic with the medium and long wavelength sensitive cone activities pooled to produce a single “longer” wavelength cone signal (Gawne et al., 2021).
Tree shrews do not maintain emmetropia in initially-focused narrow-band cyan light

2020, Vision ResearchThe hyperopic effect of narrow-band long-wavelength light in tree shrews increases non-linearly with duration
2018, Vision ResearchCitation Excerpt :Tree shrew retinas contain long wavelength sensitive (LWS “red”, peak absorption at 555 ± 6 nm spectral width at half absorbance) and short wavelength sensitive (SWS “blue”, peak absorption 428 ± 15 nm spectral width at half absorbance) cones (Petry & Harosi, 1990). As shown in Fig. 1A, the light provided by the LEDs was far removed from the SWS-cone absorption peak (Petry & Harosi, 1990). The calculated absorption of the emitted wavelengths was between 6 and 7 log units below the SWS cone peak.
Long-wavelength (red) light produces hyperopia in juvenile and adolescent tree shrews
2017, Vision ResearchCitation Excerpt :The amount of time that the animals spent in the tube was not recorded but did not appear to differ across groups. The illuminance provided by the red LEDs (Fig. 1C) was very far removed from the SWS cone absorption curve for this dichromatic species (Petry & Harosi, 1990); the effect on the SWS cones was between 5 and 6 log units less than on the LWS cones. Thus, the effect of the red LEDs (regardless of whether the peak wavelength was 624 or 636 nm) was to activate almost exclusively the LWS cones and the retinal neurons that receive red-cone inputs.
