This is Boo who is Azizi’s room mate and as you can see, she is pretty much in torpor (though critter cam showed that she was up at 5am foraging for bugs!) Her hide is directly under a UVB light and here, whilst she is enjoying some zzzz's, she is basking in the light. Little cutey.
Bright direct sunlight can be bad for your eyes.
Light is essential for our visual perception, as it allows our eyes to bring the world into focus. It enters our eyes and undergoes refraction and focusing, ultimately reaching the macula on the retina. The light is then converted into electrical signals that travel through the optic nerves to the brain. However, prolonged exposure to UVA and UVB light can cause significant damage to our eyes. Unfortunately, the primary source of these harmful rays, the sun, is both ubiquitous and challenging to avoid.
A quick tingle of your retinal cones for this week’s Sliders Sunday mangle. It’s an image of a yellow dahlia taken on my phone some years ago, mirrored in Mirrorlab (an Android app which is an interesting playpen full of toys), and blitzed with Nik Color Efex (solarisation and bicolor filters being the usual culprits of this sort of bling).
Hmmm… My sentences are assuming Dickensian proportions.
And the title? Well, my auto-tagger suggested pasta for the camera image (linked in the first comment). Who am I to disagree?
Thank you for taking the time to look. I hope you enjoy the image with your UVB-blocking, heavy-duty sunglasses. Happy Sliders Sunday :)
According to the manufacturer (Tilley) their hat provides 98% protection from UVA/UVB. During the summer months, if the sun is shining, I never leave home without it.

European tree frogs are small; males range from 32–43 mm (1.3–1.7 in) in length, and females range from 40–50 mm (1.6–2.0 in) in length. They are slender, with long legs. Their dorsal skin is smooth, while their ventral skin is granular. Their dorsal skin can be green, gray, or tan depending on the temperature, humidity, or their mood. Their ventral skin is a whitish color, and the dorsal and ventral skin is separated by a dark brown lateral stripe from the eyes to the groin. Females have white throats, while males have golden brown throats with large (folded) vocal sacs. The head of H. arborea is rounded, the lip drops strongly, the pupil has the shape of a horizontal ellipse, and the tympanum is clearly recognizable. The discs on the frog's toes, which it uses to climb trees and hedges, is a characteristic feature of H. arborea . Like other frogs, their hind legs are much larger and stronger than the fore legs, enabling the frogs to jump rapidly.
Historically, tree frogs were used as barometers because they respond to approaching rain by croaking.
Depending on subspecies, temperature, humidity, and the frog's 'mood', skin colour ranges from bright to olive green, grey, brown and yellow.
European tree frogs eat a variety of small arthropods, such as spiders, flies, beetles, butterflies, and smooth caterpillars. Their ability to take long leaps allow them to catch fast-flying insects, which make up most of their diets.
They hibernate in walls, cellars, under rocks, under clumps of vegetation, or buried in leaf piles or manure piles.
According to the IUCN, the population trend of H. arborea is decreasing. Some of the main threats to European tree frogs include habitat fragmentation and destruction, pollution of wetlands, predation from fish, capture for the pet trade, and climate change.[citation needed] Besides these main threats, other possible reasons for the decline in their populations include increased UVB radiation and local and far-ranging pesticides, fertilizers, and pollutants.

Vintage 1980 Ray-Ban Sunglasses. Width 11,5 cm cropped to 7,5 cm. Horizontal flip. Sunscreen 50 SPF reflected.
The best SunSmart steps:
1 Slip on covering clothing. Choose clothing that covers as much skin as possible, for example, collared shirts with long sleeves...
2 Slop on SPF 30 (or higher) broad-spectrum, water-resistant sunscreen...
3 Slap on a hat...
4 Seek shade...
5 Slide on some sunglasses...
Why Is Sun Protection Important?
We all need some sun exposure. When skin is exposed to the sun, our bodies make vitamin D, which helps the body absorb calcium for stronger, healthier bones. It only takes a little time in the sun for most people to get the vitamin D they need (and most vitamin D needs should be met with a healthy diet and/or supplements).
Too much unprotected exposure to the sun's ultraviolet (UV) rays can cause skin damage, eye damage, immune system suppression, and skin cancer. Even people in their twenties can develop skin cancer.
How Do Sunburns Happen?
The sun radiates light to the earth, and part of that light consists of invisible UV rays. When these rays reach the skin, they cause tanning, burning, and other skin damage.
UVA rays cause skin ageing and wrinkling and contribute to skin cancer, such as melanoma (the most dangerous form of skin cancer). UVA rays pass easily through the ozone layer, so they make up the majority of our sun exposure.
UVB rays are also dangerous, causing sunburns, cataracts (clouding of the eye lens), and effects on the immune system. They also contribute to skin cancer, and melanoma is thought to be associated with severe UVB sunburns before age 20.
UV rays react with a chemical called melanin that's found in skin. A sunburn develops when the amount of UV exposure is greater than what can be protected against by the skin's melanin. The risk of damage increases with the amount and intensity of exposure. A tan is itself a sign of skin damage and does not help protect the skin.

Lebensraum und Verhalten:
Grüne Leguane sind in den tropischen Regenwäldern Mittel- und Südamerikas beheimatet, bevorzugen feuchtwarme Umgebungen mit dichter Vegetation und leben oft in der Nähe von Gewässern. Sie sind hervorragende Kletterer und verbringen die meiste Zeit in Bäumen.
Aussehen:
Obwohl sie "Grüner Leguan" genannt werden, kann ihre Färbung variieren und auch bräunlich-gräulich oder leuchtend orange sein, besonders bei erwachsenen Tieren. Sie können eine Länge von bis zu 2 Metern erreichen, einschließlich ihres langen, peitschenartigen Schwanzes.
Ernährung:
Grüne Leguane sind Pflanzenfresser und ernähren sich ausschließlich von Blättern.
Haltung:
Als Terrarientiere benötigen sie ein geräumiges Terrarium mit ausreichend Klettermöglichkeiten und einem warmen, feuchten Mikroklima. UVB-Beleuchtung ist für ihre Gesundheit unerlässlich.

LXZ 5401 is a Volvo B9TL/Wright Eclipse Gemini new to Centrewest in October 2010 as BF60 UVB (VN37932).
It later operated for Metroline as their VW1884 before joining the Lothian Buses fleet as their 1017.
Heh, been a while since I've posted. I'm not dead, just extremely busy!
As per commission, I've made a figure based on this, but with a different weapon and some modifications.
This was extremely fun to make, as I got to use a casted version of my slimmed torsos, hips, and legs (a product I'm thinking of offering). Additionally, I sculpted a helmet cover over a heavily modified Combat Brick helmet, using Tiny Tactical's amazing helmet rails and NVG mount. The rails on the gun were sculpted, along with most of the pockets and a few pouches.
This was also my first time painting multicam and woodland camo on a figure.
Please check out my instagram @avxtc_designs to see more frequent updates and WIPs! I post a lot more on there, and you'll get a chance to see some of my casted projects that I'll be releasing very soon. So as always, expect more, and I'd love to hear your thoughts!

Walking home from the pub.
(The Half Moon in Clayhidon, Devon).
At least its "down hill" on the way back.
(Photochromic lenses - dark even when its cloudy - the clouds don't stop all of the UV so the lenses react.
Here is some interesting information:-
Clouds usually block UV rays, particularly UV-B; on a really overcast day they can keep out 70 to 90 percent of the UV-B coming in.
Oddly enough, that's not where it ends. Under partly cloudy conditions a phenomenon sometimes called the "broken-cloud effect" can come into play, resulting in higher UV levels than a clear sky would produce, and so a greater risk of sunburn - or worse. A survey conducted at 6 U.S. sites in 1994 found that cumulus clouds could raise surface UV-B measurements by 25 percent, and in 2004 Australian researchers reported that the specific UV-B frequencies associated with DNA damage were up to 40 percent stronger under somewhat cloudy skies.)
