Krill Oil and the Eyesight Theory


One of the krill oil benefits you may have heard of is that it can help to improve eyesight, but is it true? Well, have you ever heard the saying “we are what we eat?” It's true, we are. What we put into our mouths affects every single bodily function. Eat bad food and nothing works as well as it could do, including your eyes. Older eyes in particular can respond very well to good nutrition, and krill oil is certainly that. This is not to say that omega 3-rich krill oil supplements will improve or repair all eye conditions. That would be wishful thinking.

Science suggests krill oil may help to maintain eyesight or even restore failing vision in some cases. Here are some common eye problems this special oil can help with.

Dry Eye Syndrome

This is a condition that can cause a range of unpleasant eye issues, including:

  • Blurred vision (intermittent)
  • Buildup of mucus (under eyelids)
  • Gritty feeling in the eyes
  • Persistent itching
  • Puffiness (can also cause dark circles)
  • Redness
  • Swelling

It's thought that between 20 to 30 percent of adults over the age of 40 suffer with some degree of vision impairment caused by dry eyes. Omega-3 fats from krill oil may help to restore the viscosity of tears, thus keeping the eyes functional and moist. Improvements are not immediate and make take up to three months for the supplements to work their magic. Talk to a doctor or nutritionist if you have any questions about duration, expectations and dosage.

OK, other eye conditions that may benefit from krill oil include the following:

  • Age-Related Macular Degeneration
  • Diabetic Retinopathy
  • Glaucoma

Krill oil can provide your body with more omega-3 fatty acids than it can use. There is plenty of science out there to back up the many health claims to this natural, potent supplement. Some are conclusive, others not, and many more under study. So far, there's a lot of positive buzz surrounding krill oil supplementation, including ophthalmological.
