Chlorophyll Eye drops improve Night vision ?

... latest experiments in mice and rabbits suggest that administering chlorophyll to the eyes can double their ability to see in low light. The pigment absorbs hues of red light that are normally invisible in dim conditions. That information is then transmitted to the brain, allowing enhanced vision.
Washington is now developing ways to deliver chlorophyll to human eyes safely and easily, perhaps through drops. He believes that a night-vision drug would be most useful on the battlefield, so it is no surprise that the U.S. Department of Defense is funding his work. "The military would want this biological enhancement so they don't have to carry nighttime goggles" during operations in the dark, he says.

Chlorophylls help eyes see red
31 May 2007
Eating your greens rather than carrots could be the key to good night-time vision, according to scientists in the US. Ilyas Washington and colleagues at Columbia University, New York, have shown that a chlorophyll derivative can enhance eye sensitivity to red light
Chlorophyll derivative chlorine e6 enhances eye sensitivity to red light.In sight, light activates a visual pigment that sends an electrical signal to the brain. This process happens in the retina in cone and rod cells. Rod cells are insensitive to colour and the cone cells are mainly responsible for our colour vision. However, in dim light the cone cells cannot function and we largely perceive the world in black and white. This also means we are dependent on rod cells to see in the dark. Since these cells are particularly insensitive at the red end of the visible spectrum, Washington asked: 'How might one enhance red light night-time vision?'
"It is possible that taking a chlorophyll derivative supplement could improve night vision"
- Ilyas Washington Prompted by research suggesting that deep-sea dragonfish see using chlorophyll, the scientists gave mice a chlorophyll derivative, chlorin e6, to see if their red vision was improved. Using a technique called electroretinography, which measures retinal cell responses to a flash of light, the researchers found that the treated mice showed almost double the response to red light when compared to non-treated mice. The group also showed that the chlorin e6 was localised in the retina and conclude that the increased visual sensitivity is a result of light absorption by the chlorophyll derivative.Washington is currently performing similar research in people. It is possible that taking a chlorophyll derivative supplement could improve night vision, he said.

Chlorophyll derivatives as visual pigments for super vision in the red.

The primary event in vision is light-initiated activation of visual pigments. All visual pigments consist of the protein opsin bound to 11-cis-retinal and are responsible for initiating the transformation of light into an electrical signal. In a mouse model, we show that derivatives of chlorophyll can act as visual pigments initiating the transformation of light into an electrical signal and thus change the primary event in vision to initial activation of a chlorophyll derivative. Electroretinographic b-wave amplitudes recorded in response to red and blue light were two-fold greater in mice administered chlorin e(6), which accumulated in photoreceptor outer segments.

Porphyrins as photosensitizers to enhance night vision.
Washington I, Brooks C, Turro NJ, Nakanishi K.
Department of Chemistry, Columbia University, New York, New York 10027, USA.
Relative bleaching rates of bovine rhodopsin (rod outer segments) in the presence and absence of seven porphyrins and methylene blue were measured under exposure to lambdamax = 675 nm light, using UV-vis spectroscopy. Rate enhancements on the order of up to three times compared to the bleaching of rhodopsin alone where observed. Fluorescence measurements and other data suggests that the porphyrins act as photosensitizers and excite the visual pigment via electron or triplet state energy transfer. These mechanisms suggest that rhodopsin possesses a pocket, proximal to the Schiff base so that porphyrins act as photosensitizers.

Would a product like this work, maybe diluted to a specific concentration???
http://www.herbsetc....loro_bro_07.pdf
yeah um no... It's a derivative of a specific type of chlorophyll.
You can get it here.

Many synthetic non-porphyrin compounds demonstrate photosensitising ability. These include: phenothiazinium compounds such as methylene blue ; Toluidine blue , which has found widespread use in the diagnosis of oral disease; cyanines such as Merocyanine 540; acridine dyes as demonstrated by Raab in 1900; derivatives of the tumour marker, Nile blue; and rhodamines such as the mitochondria-specific Rhodamine 123.

You know what else might work ? Methylene Blue.
Tell me at what concentration per drop and I will totally put it in my eye.

Bilberry is used for this purpose. In fact, RAF pilots used to eat bilberry jam before night missions. I've seen bilberry eyedrops somewhere but can't find them at the moment. bulk powders are also available (don't know if it's a good idea to put these in your eye, but ingesting them is fine).

The legendary RAF story may be just that. From the third reference in the Wikipedia entry,
"In all my work on the RAF Bomber Command, I've never run across any reference to bilberry whatsoever"

I'm gonna setup a greenhouse and try to get them to sprout.
