Individual variation in the transmission of UVB radiation in the young adult eye

The large individual differences in UV reaching the retina of younger individuals suggests equally significant vulnerability to the actinic effects of this highly energetic light.

Ultraviolet Phototoxicity to the Retina

Although the anterior portion of the eye is the most susceptible to UV damage, the retina is at risk to the longer UV wavelengths that propagate through the ocular media and may be counteracted or reduced by dietary intake of antioxidants and protective phytonutrients.

Photons, Clocks, and Consciousness

Action spectra in humans show that the peak wavelength sensitivity for this newly discovered sensory system is within the blue portion of the spectrum, which opens the door to innovations in light therapy for circadian and affective disorders, as well as possible architectural light applications.

Cryptic impact: Visual detection of corona light and avoidance of power lines by reindeer

It is suggested that spatial and temporal variability of corona contributes to substantial variation observed in the strength and persistence of avoidance responses in Rangifer at high-voltage power lines, and may partly account for the tendency of the animals to avoid power lines.

Color Responses of Flash Visual Evoked Potentials in Normal Adults, Normal Elderly Subjects and Dementia of the Alzheimer Type Using Light Emitting Diodes

Green light goggle‐shaped stimuli equipment with LEDs was developed on the request of Nihon Kohden (Tokyo, Japan) in 1999 on the basis of information concerning different color responses of visual evoked potentials.

The circadian activity rhythm is reset by nanowatt pulses of ultraviolet light

It is shown that Drosophila activity rhythms can be phase-shifted by UVA light at an energy range seated well below that of the visible spectrum, suggesting that UVALight has the potential to function as a similar time cue in people.

Mitochondrial abnormalities in ageing macular photoreceptors.

The results show that mitochondrial DNA deletions and cytochrome c oxidase-deficient cones accumulate in the ageing retina, particularly in the foveal region, and may contribute to the changes in macular function observed in ageing and age-related maculopathy.

Coenzyme Q10 protects retinal cells from apoptosis induced by radiation in vitro and in vivo

In the rat, CoQ10, even when applied as eye drops on the cornea, protected all retina layers from UVR-induced apoptosis, suggesting the possibility for Co Q10 eye drops to become a future therapeutic countermeasure for radiation-induced retinal lesions.

Is there any proof of UV-sensitivity and its role in king penguins (Aptenodytes patagonicus)?

It is argued that based solely on the microspectrophotometric analysis of two Humboldt penguin retinae, without electrophysiological spectral sensitivity measurements and spectral transmission records for the dioptric structures, there is no hard evidence for UVvision in king penguins.



The effects of ultraviolet-A radiation on visual evoked potentials in the young human eye.

It is demonstrated that monochromatic UV-A can elicit age and dose dependent responses in the human visual system, suggesting that the eyes of children are more responsive to UV stimuli than the Eyes of young adults.


The purpose of this review is to integrate what is known about UV vision in invertebrates, which have been particularly well studied, with a growing literature on UV sensitivity and UV effects in the visual systems of humans and other vertebrates.

Transmission of the Ocular Media

The spectral transmittance of ultraviolet, visible, and near infrared light through the ocular media of humans has been measured and shows that the transmission of ultraviolet radiation decreases with the age of the eye.

The photosensitivity of visual purple solutions and the scotopic sensitivity of the eye in the ultra-violet

The limit of vision in the ultra-violet was accurately determined and, for normal eyes, found to correspond to the threshold of absorption of the lens, 309 mμ, and the limit for the aphakic eye (no lens) corresponded to the thresholds of absorb of the cornea, 298 mμ.

Ultraviolet photosensitivity in goldfish: An independent U.V. retinal mechanism

Near-ultraviolet radiation suppresses pineal melatonin content.

Experiments on hamsters confirm that wavelengths as low as 305 nm are transmitted through the clear ocular media to the retina, and low irradiances of broadband and monochromatic UV radiation are capable of suppressing high nocturnal levels of pineal melatonin in intact, but not blind, hamsters.

Visual evoked potentials: relation to adult speechreading and cognitive function.

This study investigated the putative relationship between visual evoked potentials (VEPs) and specific aspects of speechreading and found significant correlations for some context-free word discrimination and sign-alphabet testing conditions.

Hummingbirds see near ultraviolet light.

Three species of hummingbird were trained to make visual discriminations between lights of different spectral content and birds of all three species were able to distinguish near ultraviolet from darkness or from the small amount of far red light that leaked through the ultraviolet-transmitting glass filter.
