Canned salmon improves aged eyes (presbyopia).
Astaxanthin which is a substance contained in canned salmon improves aged eyes.
We can change the thickness of the lens in the eye with ciliary muscle and focus on what we want to see. But as we age, increased active oxygen attacks the ciliary muscle and the function of the ciliary muscle declines, causing to unable to change the thickness of the lens. This condition is aged eyes. (Fig. 1)
But when you eat canned salmon, astaxanthin contained in canned salmon removes the active oxygen, the function of the ciliary muscle is restored and you can focus on what you see.
If the lens is not already very hard, aged eyes can be improved by eating canned salmon.
Check the degree of aged eyes
If you are wearing reading glasses, take them off.
If you are wearing contact lens or glasses for nearsightedness, keep wearing them.
(1) Hold the pad of your index finger in front of your eyes (Fig. 2).
(2) Move your index finger away and stop when you can focus your eyes on the finger print (Fig. 3).
(3) If the distance between your eyes and the finger is more than 30 cm (1 foot), you have aged eyes (Fig. 4).
The longer the distance, the higher the degree of aged eyes.
How much canned salmon and how long should be eaten to improve aged eyes?
1 canned salmon (about 200 grams (7 oz.)) a day for 2 weeks should be eaten to improve aged eyes.
Sockeye salmon is recommended.
It is recommended to eat canned salmon with sesame oil because astaxanthin is dissolved in oil, so eating canned salmon with sesame oil raises the absorption ratio by liquefying astaxanthin.
Astaxanthin decreases on the way to the eye by being attacked by active oxygen in the blood vessel, but the substance contained in sesame oil, which is called sesamin, protects astaxanthin from active oxygen and makes more astaxanthin reach the eye.
A 52 years old female whose degree of aged eyes was 2 ate 1 canned salmon a day for 2 weeks. 2 weeks later her degree of age eyes was improved from 2 to 1.
