An ultraviolet (UV) ray detector is a device which uses photoelectric cells to detect the presence of UV rays and the amounts in which they can be found.
UV rays are emitted primarily by the sun, but also by certain light emitting and electronic devices, such as black lights and tanning beds.
The use of a UV detector may also come in handy with consumers for finding out how much UV radiation is entering their homes and buildings through windows and certain electronic devices. Most times the UV detector will need to be connected to a printer or computer in order to view readings. You must have JavaScript enabled in your browser to utilize the functionality of this website.

Everybody sees the world around them in different ways and although this is usually down to interpretation, some people can physically see more of the world around them. I’ve often heard that Monet had Ultraviolet vision and examples of how widespread this is thought can be found in this article in the Science section of the Guardian and in this article in the Daily Mail. In this article I’m going to be doing some research on whether this is possible and whether this is probable. An image showing Claude Monet’s paintings of water lilies before and one after cataract surgery.
From early on in his career Monet rejected traditional methods of painting and didn’t want to paint what he knew was there but what he actually saw. When you go out to paint, try to forget what objects you have before you — a tree, a house, a field. He wanted to create an impression of a scene at a particular time and capture what it was like at that particular moment. This diagram pretty clearly shows how how small the spectrum of light as part of the spectrum of electromagnetic radiation really is.
A retired Air Force Officer and Engineer called Alek Komarnitsky underwent cataract surgery in 2011.
After undergoing this operation he appears to have become more sensitive to the low end of the visible light spectrum. The team at The Skeptics Guide to the Universe also seem convinced and if you listen in about 17 minutes into podcast 413 from June 15th 2013 they also mention Monet and his UV vision. Not entirely relevant but just as exciting are experiments currently being performed to create retinal implants that could be used to cure some kinds of blindness.
Digital cameras are generally manufactured with a filter over the sensor that stops them from recording Ultraviolet and Infra Red Light. Many portraits taken using only UV light between the wavelengths of 335 and 365 nanometers to create images with a similar stunning effect.
These are Monet’s thick tinted glasses it seems unlikely that UV rays could pass through these lenses. I asked my wife what she saw (she recently had cataract surgery) and she could only see the smoked glass, no white lights. I have recently (4 months ago) sugary to remove the cataracts in both eyes and replace the clouded lenses with new plastic intraocular lenses.
In the late 1970s and early 1980s about 5000 people had the first artificial lens implants before they discovered that the lenses needed uv filtering. In the 1950s, when aphakics still wore glasses with Coke-bottle lenses, they were studied by vision researchers. I happened to be searching to determine why I cannot see fluorescence from UV illuminated objects through my IOL, but can through my natural lens.
During my wandering, back burner search, I arrived here and at a page written by a man who documented his IOL experience and his ability to see into UV. It rather makes me wonder if we really should study, yet again, the full range that is normal in our population. Hi, my 20 year-old daughter has been able to see ground level plasma waves as they float along the ground or build to shoulder height.

These occur as waves that flow down a hill or hover at ground level like evening fog or morning mist.
When walking through this plasma, it will swirl like smoke that’s been interfered – like that of a hand passing across smoke.
I’ll ask her what the ground plasma looks like during a day that I know has an increased level of ground magnetism (especially after arrival of a CME, Coronal Mass Ejection from the sun), and she’ll tell me it’s more intense or … greatly decreased on lower magnetism days well after a CME. When certain clouds appear that show greater energetic plasma characteristics she will confirm this in the increased ground plasma she sees. Lots of fun to have her confirming past solar events reaching Earth when I haven’t checked the solar data for a few days. A magnetogram maps the magnetic field – white areas have a strong magnetic field, black areas have a weak magnetic field. They are generally used to test lighting fixtures and electronics to discover the amounts of UV emitted before being sold to consumers.
When used in correct doses, UV rays can have health benefits like increased vitamin D production and treatment for some skin conditions. This is a good idea for anyone attempting to use items that are meant for UV ray production to ensure that they are not getting too much too quickly. Some detectors may also be useful at detecting the presence of UV radiation above a certain level, while others can give exact readings on the amounts of UV radiation being emitted by particular items.
I’m entering this investigation with an open mind, a background in Art History and an interest in the facts.
From 1900 onwards Monet had problems with his vision and complained to his friends that everything he saw was a fog. His palette which before the operation had been red, brown and earthy took on a more bluish hue.
People often claim that Monet’s blurred style was a result of cataracts in an aging artist but this appears to be false in that he painted in this style from a young age. This is a pretty common operation which according to wikipedia is performed on over 2 and a half million people a year in the United States. These implants would enable users to see a full spectrum of light rays that are not ordinarily visible. Insects including bees can see Ultraviolet and this can help them navigate and find flowers. I know this sounds odd but I was on vacation with my wife and she was looking at shirts that when you go out into the sun they change color. It makes me think that there may be more variety in how people see things than I originally thought. When I got the first eye done I was riding home on the bus and I took the eye patch off and the new lens showed the entire world was more blue.
Between 420 and 380 nm the lens becomes increasingly opaque by one or more orders of magnitude (depending on age). Indeed, in a darkened room, if someone turned on a large UV bulb, it was a near white-out in blue for me, painfully so as an intense brightness discomfort. It seems to be averaged down substantially, to judge from what I’ve read in various places and indeed, from my own personal experience.
On a subsequent visit to Walt Disney World, I discovered that the UV light that they use to illuminate the dark rides is quite visible in the eye with the Akreos lens. UV detector devices can also be used by consumers to find out how much UV radiation is in their homes, businesses, and other locations and sometimes where the rays are coming from.
In higher amounts, UV radiation can cause serious damage to skin’s DNA and may result in skin cancer. Many industrial companies must also frequently test their facilities for UV rays to ensure the health of their employees. Each model has a different level of sensitivity and can detect levels below a specific point and above. He only lived for 3 years after his cataract operation and there are relatively few paintings that can be attributed to that period.

Although cataract operations had been performed for thousands of years they were still a risky business at the time.
The rod and cone cells in our retina have the potential to detect light down to 290nm, but our lenses block out everything below about 390nm. By testing with a Monochromator at Hewlett-Packard, Komar was able to see purples at around 350nm and tiny bits of brightness down to 340nm.
By then using different filters on the front of your lense you can make sure that your camera only takes photographs which record a certain spectrum. There are also certain Butterflies where both genders look exactly the same to us but to each other (or someone who can see UV) the males have bright patterns which may help them to attract mates. I hadn’t realised how much information there was on the subject but come back soon as I will continue to look into this. I figured out that the cataract was a yellowish cloud over and in the lens and it made the world look warmer and for a moment I thought more pleasant.
I know that dopamine can dilate your pupils but I’m not sure how it affects your vision. For this reason, a UV detector should be used for any product meant to treat patients with low levels of ultraviolet rays to ensure that they do not receive an overdose.
The level at which many can detect UV rays is at or just below that which would be harmful for humans with prolonged or repeated exposure. He agreed to surgery to totally remove the lense in his left eye in 1923 at the age of 82 and the operation was a success. Komarnitsky, Klaus D Schmitt, William Stark who have been really helpful and provided me with fascinating information for a follow up article.
Normals can see a gray blur at 300 nm, with dark-adapted eyes and looking at very bright uv. Through the Akreos lens, it looks as though a very bright bluish-white light is illuminating the room. Pair this great quality UV black light with our fluorescent rock set to see the rocks glow!
Merely think, here is a little square of blue, here an oblong of pink, here a streak of yellow, and paint it just as it looks to you, the exact color and shape. There were no replacement implant lenses at the time and he had to wear thick glasses but his vision was transformed.
Since then i read more aboutMonet and that he had an eye operation to remove the catarct lens . Black lights are a perfect example – where someone with normal vision may see a dim, dark purple glow from a black light bulb I see a bright purple light that is painful to look at. I liken the effect to what happens when only one pupil is dilated and there is a huge difference in the amount of light reaching one eye versus the other.
I think getting in touch with your surgeon is always probably the best option if you’re concerned but from what I have read this seems more common than I thought. He had to wear thick corrective glasses ans they had no way to put in the intraocular lens.
Oddly enough I first noticed this while attending a baseball game at the Astrodome in Houston when I realized I could see black lights from vendors on the other side of the stadium! When I had my six month followup visit with my ophthalmologist, he was surprised by my ultraviolet vision because the Akeros AO60 is supposed to block all wavelengths below 400nm.
I have astigmatism in both eyes so I will soon get a new prescription filled and have to wear glasses. I chose notto try the new lenses to correct that because they cost $5,000 and my insurance doesn’t cover them.
