Blueberries help improve eyesight

The nutrients and vitamin A in blueberries help maintain and enhance eyesight.

Blueberries (Vaccinium myrtillus) are one of the richest natural sources of anthocyanidins, and have long been used in traditional European medicine. During World War II, Royal Air Force pilots reported improved night vision after eating blueberries.

Blueberries have many benefits for human health, especially for the eyes.

According to the British Journal of Nutrition (2005), blueberries have been tested many times to prove their effect in improving eyesight.

Trial 1: High dose purified anthocyanoside oligomer (bilberry extract) in improving night vision and clinical symptoms in myopic subjects.

Study: Randomized, double-blind, placebo-controlled trial involving 60 subjects with asthenopia and myopia of 1-8 diopters in both eyes.

Two groups: Group 1: took 100mg anthocyanoside oligomer 85% (blueberry extract) twice daily.

Group 2: took a placebo (same ingredients as group 1 but without anthocyanosides) twice daily.

Results: Proportion of subjects with improved symptoms in the 2 groups

Conclusion: Use of anthocyanoside oligomer improves symptoms in myopic and astigmatic subjects.

Trial 2: Evaluation of Anthocyanosides extracted from blueberry (Vaccinium myrtillus) in neurodegenerative and visual impairment.

Study: randomized, double-blind, cross-over, conducted on 20 patients.

Two groups:

Group 1: took 62.25 mg of anthocyanoside extracted from Vaccinium myrtillus

Group 2: took a placebo (same ingredients as group 1 but without anthocyanoside).

10 typical symptoms of visual impairment were assessed: eye fatigue, blurred vision, headache,…

Result:

During the first 4 weeks, symptoms improved more quickly and significantly. Symptoms improved less slowly and significantly.

During the next period, 6/10 symptoms continued to improve. Symptoms did not improve further.

Side effects: No complaints were noted in either group.

Anthocyanosid oligomer found in blueberries helps improve symptoms in people with myopia and astigmatism.

Experiments show that blueberries are a good food for the eyes, especially for children who are nearsighted and at risk of nearsightedness. However, this is a difficult plant to grow, so few gardeners grow them. Blueberries are grown mainly in European countries such as Italy, Finland, Sweden, Norway, Wales, parts of England, the Alps, the Carpathians in Ukraine...

In Vietnam, to use fresh blueberries currently only through import, so it is quite rare and not often available. Parents can supplement nutrients from blueberries through preparations extracted from blueberry extract.
