I heard that consumption of Alaska fish oil may improve child's myopia. Is there any basis for such consumption ?

Not too sure about fish oil being a remedy for myopia but I heard that some people use fish oil for dry eyes, cataracts, glaucoma, and age-related macular degeneration, a very common condition in older people that can lead to serious sight problems. My late grandfather had cataracts in the last few years of his life and I remember him taking doses of fish oil everyday.
