Additionally, vitamin C aids in preventing oxidative damage. Oxidative harm is a vital factorTrusted Source in two of the most widely recognized age-related waterfalls: cataracts in the nucleus and cortex. Nuclear cataracts occur deep within the center of the lens, whereas cortical cataracts develop on the lens’s edges.
Different factors that may assist in preventing the development of nuclear cataracts were investigated in a ten-year longitudinal study. There were over 1,000 pairs of female twins in the study. Participants who consumed more vitamin C had a 33% lower risk of cataract progression at the study’s conclusion. They additionally had more clear focal points by and large. Still, a review published in 2020 by Trusted Source came to the conclusion that fresh exploration is needed to completely identify the part of vitamin C as an anticataract remedy.

Vitamin C-Rich foods

B Vitamins

Reviewing 2015According to a reliable source, persons tend to have lower blood levels of B12. Researchers did find insufficient data to support a clear connection, though. Therefore, more investigation is required to support the use of B vitamins in preventing AMD in both men and women.
2018 National researchAn association between glaucoma and lower consumption of vitamin B3 (niacin) was discovered by Trusted Source in South Korea. An accumulation of fluid inside the eye puts pressure on the optic nerve in glaucoma patients. This can harm the nerve over time and cause vision loss. A small 2020 study discovered that mecobalamin and vitamin B1 supplements may lessen the signs and symptoms of dry eye illness.

B Vitamin-Rich Foods

The following foods have high concentrations of different B vitamins:
  • Vitamin B1 (thiamine): yogurt, green peas, pig, salmon, and beans

Lutein and zeaxanthin can be found in:
  • Egg yolks
  • Corn
  • Asparagus
  • Broccoli

It may be profitable for those who have AMD or are at threat of developing the condition to take zinc supplements. Taking antioxidants and 40 – 80 mg of zinc every day can decelerate the progression of AMD by 25. also, it might halt a 19 loss in visual perceptivity.
