Dry eye syndrome is characterized by insufficient moisture in the eye. The problem may be a result of insufficient tear production or poorer quality of tears produced, causing the tears to evaporate more quickly than normal.
The syndrome is widespread. Dry eye risk increases as one gets older. The disease appears to occur more commonly in women than men. Roughly nine out of ten dry eye sufferers are women, particularly those in the menopausal stages.
Various symptoms come with dry eye syndrome. You may feel stinging pain, itchiness, rawness, powdery sensations, raspiness, and foreign body sensation in the eye. Your eye becomes ultra- sensitive to light and vision becomes milky. You may If you wear contact lenses, you may become averse to.
The symptoms derive from a variety of causes. Inflammation (due to rheumatoid arthritis, Sjögrens syndrome, eyelid infections and other inflammatory agents) is a very common cause of dry eye symptoms. Long-term usage of contact lenses can also lead to dry eye syndrome, as well as working long hours at a computer or behind the wheel of a car. Evaporation of tears from your eyes can be caused by environmental conditions that vaporise moisture from your skin.
Ophthalmologists use different strategies to address dry eye syndrome. The primary aim of therapy is to keep eye lubrication up and to keep inflammation to a minimum, but the eye health care professional will also try to determine any latent health conditions that may be the real cause of dry eye.
Krill is a minute shrimp-like crustacean. It is very abundant in the Earth's Polar Regions, where the waters are very cold and, relatively speaking, still quite pristine. They are food to whales, salmon, and other oceanic fish species.
Oil extracted from krill contains significant amounts of omega-3 fatty acids. Krill oil consists of about 44 per cent omega-3 fatty acids of which 19.2 per cent is eicosapentaenoic acid (EPA) and 14.1 per cent is docosahexanoic acid (DHA). These two are the most valuable forms of omega-3s, because they are more bio-available (that is, more readily assimilated) and utilised in cell metabolism than other types of omega-3.
existing in fish oils. There is a difference in the molecular structures, however. Fish oil DHA and EPA come in the form of triglycerides, whilst krill oil DHA and EPA are expressed as a double-chain phospholipid structure. The structural difference determines their bio-availability. Human cells assimilate only fatty acids structured as phospholipids.
This only means that DHA and EPA derived from krill oil are better than those drawn out from fish oil in terms of bio-availability. Indeed, because of its superior bio-availability, you need only 2-3 capsules (about 500mg) of krill oil per day to obtain an effective therapeutic dose, compared to as many as 10 capsules a day for fish oil. Omega-3 fatty acids can hold back inflammations very effectively. Because of this krill oil can be a vigorous means for limiting the inflammatory reactions that give rise to dry eye syndrome.
Just as important, krill oil is a plentiful source of astaxanthin, with 217mg of astaxanthin per gram of krill oil. Astaxanthin is said to be Nature's most potent antioxidant. It is far better than beta-carotene and vitamin E in capturing free radicals in your system.
For the eye in particular, astaxanthin safeguards against retinal deterioration from ultraviolet light. Research reports have described how astaxanthin works better (by up to 200 or even 1000 times!) than beta-carotene and lutein at counteracting fatty acids breakdown induced by UV light. This potency is particularly beneficial to the eye which, along with the skin, are the organs of the body most threatened by ultraviolet light. Krill oil, owing to its high astaxanthin content, helps minimise the ultra-sensitivity to light suffered by dry eye patients.
People who experience allergic reactions to shrimp and crustacean species refrain from taking krill oil. Both krill oil and fish oil act as blood thinners so it is essential to stay away from them if you are about to undergo surgery.
