by ROSALIND RYAN, femail.co.ukYour mother's advice that carrots can help you see in the dark may have been more than a ploy to get you to eat vegetables. Research has now proved that eating certain foods can improve your eyesight, reverse the signs of optical ageing and keep your eyes in good health.One of the most common causes of poor sight is a condition called macular degeneration. This condition accounts for 50 per cent of all blindness and sight problems in the UK. Imagine that your eye is like a camera. There is a lens and an opening at the front that focuses objects onto the retina at the back of your eye. The macula lies in the centre of the retina, which is sensitive to light. Sometimes the cells of the macula become damaged and you lose the ability to appreciate colours or focus on detailed activities like reading. The condition rarely causes total blindness but can blur your central vision and sometimes make you sensitive to light. It normally affects those over 60 years old, earning the name age related macular degeneration (ARMD), but a genetic form of the condition can also affect children and young people.

Doctors do not know exactly why the cells of the macular start to fail. One theory is that ARMD is triggered by free-radicals, harmful chemicals that your body picks up from sunlight, the atmosphere and cigarette smoke. But there are some steps you can take to protect your eyes for the future. Follow our guide to eating your way to better eyesight. A recent study by the Florida International University found that eyes containing higher amounts of a nutrient called lutein were up to 80 per cent less likely to be suffering from ARMD. dynamic air cleaner 16x25Lutein protects the eye by forming pigments in the macula. thermax to present water-based air purifier & air freshenerThe pigments help with vision by filtering out harmful blue light wavelengths that can damage the eye. dinkydoodle airbrush cleaner

The more pigments your eye contains, the less likely it is to fall prey to ARMD.The Eyecare Trust, a national charity devoted to raising awareness of eye health, says, 'There is increasing evidence to show that eating vegetables containing lutein is crucial to maintaining pigment density levels in the macula.' Unfortunately lutein is not generated naturally by the body so you need to make sure you are getting enough from other sources. These are mainly green leafy vegetables like spinach, broccoli and kale. A study in the American Journal of Clinical Nutrition found that eating a teaspoon of green leafy veggies with a small amount of fat raised blood lutein levels by nearly 90 per cent. You need to eat lutein-rich vegetables for several months before seeing any benefits. But if you get bored of eating spinach, you can take a vitamin supplement to boost your lutein levels. These are available from all major health food stores. A study published in Investigative Ophthalmology and Visual Science discovered that volunteers taking 10 mg of natural lutein supplements every day for 12 weeks significantly increased the amount of macular pigment in their eyes.

It is true - eating carrots can help you see in the dark. The essential nutrient responsible is carotene which is turned into vitamin A by the liver.Vitamin A protects the eyes by helping to absorb the light energy that passes into the eye. Increased levels of vitamin A means your eyes can absorb more energy and become more sensitive in dim light, helping you see more effectively. Karen Sparrow, spokeswoman for opticians Vision Express, says, 'Children that are deficient in vitamin A often have dry eyes and in extreme cases can suffer from night 'blindness' where they have trouble seeing in the dark.'Good sources of carotene are carrots, mangoes and cabbage. You can also find it in cod liver oil, milk and eggs.Another fruit famed for its ability to boost night vision is blueberries. Anecdotal evidence from RAF pilots in World War Two shows they felt their night vision improved after eating blueberries.The 'magic' ingredient in blueberries is a group of compounds called anthocyanosides.

These attach to the area of the retina that is responsible for adjusting the eye to see in the dark. You will need to eat blueberries for more than two months before starting to notice any effects. If they are difficult to get hold of, you can take them in capsule form or tablets, available from good health food shops. Aim to take up to 600mg every day.

In August, 2015, I reported that J. Marvin Herndon had published a conspiracy theory paper in the MDPI journal International Journal of Environmental Research and Public Health. After my blog post was published, MDPI quickly retracted the article. Now a very similar paper has just appeared in Frontiers in Public Health. The paper is entitled “Human and environmental dangers posed by ongoing global tropospheric aerosolized particulates for weather modification.”

Frontiers states that the paper was “edited by Judi Krzyzanowski, Krzyzanowski Consulting, Canada” and “Reviewed by Otto Andersen Stiftinga Vestlandsforsking, Norway [and] Yue-Wern Huang, Missouri University of Science and Technology, USA.” In the new paper, Herndon again theorizes that the government is spraying coal fly-ash into the atmosphere: In contrast to the presumption of academic geoengineers, covert government/military geoengineering activity has occurred over the past 70 years and has intensified since the end of the Cold War and the discovery of global warming as a national security issue (20). Later in the article he writes, The government/military solution to inhibit the fall of rain is to deliberately add an aerosolized pollutant to the region where clouds form to interfere with raindrop nucleation. The intentional addition of particulate pollution not only inhibits the fall of rain but also warms the atmosphere (by absorbing solar energy) and limits loss of heat radiated by Earth.

Consequently, the particulate pollution creates an artificial increase in air pressure, which can block the movement of an oncoming weather front thus further keeping the sprayed area from experiencing rainfall (22, 23). Comments left at the end of the article are beginning to detail the article’s flaws. This article has a fundamental methodological flaw in that it only compares the composition of rainwater and air particulates to coal fly ash and nothing else. Soil samples should have been used as controls. Also, a statistical analysis is completely missing. The total lack of controls and the lack of statistical analysis renders the article unsound and its conclusions invalid. The publication of this article is further evidence that Frontiers is little more than a vanity press. The fringe science published in Frontiers journals stigmatizes the honest research submitted and published there. I suspect that no honest publisher would have accepted this article. That’s why conspiracy theorists such as Herndon go to MDPI and Frontiers when they want to publish something — the acceptance and publication are all but guaranteed, as long as the author fee is paid.
