Ophthalmologist Mikhail Konovalov has urged Russian television viewers to consume foods rich in vitamin C regularly to protect vision and prevent cataract development.
Speaking on the medical broadcast Live Healthy on Russia's Channel One network, Konovalov stated that maintaining adequate vitamin intake is vital for long term eye health. An episode of the health program featuring his recommendations was made available on the network's official website.
Konovalov explained that dietary vitamin C actively hinders the formation of cataracts. A cataract is a widespread medical condition characterized by the progressive clouding of the natural eye lens, which impairs light transmission and can lead to severe visual impairment or blindness if left untreated. Cataracts remain one of the primary causes of preventable vision loss worldwide, particularly among older adults.
Top dietary sources for eye protection
Co-host and physician Elena Malysheva expanded on the advice during the broadcast, identifying the specific food items that supply the highest concentrations of the nutrient. She noted that sea buckthorn, blackcurrant, and yellow bell pepper contain the greatest amounts of vitamin C.
Vitamin C, also known as ascorbic acid, is an essential nutrient and antioxidant that helps shield body tissues from oxidative damage. Yellow bell peppers contain significantly higher levels of vitamin C per serving than common citrus fruits, while sea buckthorn and blackcurrant are traditional berries renowned for their high concentration of protective compounds. Because the human body cannot produce vitamin C on its own, it must be acquired through daily diet.
The health program Live Healthy is a flagship daytime medical and lifestyle television show on Channel One, Russia's principal national broadcaster. Anchored by Malysheva alongside medical specialists such as Konovalov, the show provides daily public guidance on disease prevention, nutrition, and wellness.
Previous advice on eye safety
The recent dietary recommendations follow earlier warnings provided by the two medical presenters on the same television broadcast regarding proper eye protection in daily life.
In a previous episode of Live Healthy, Malysheva and Konovalov warned viewers against wearing dark sunglasses that lack proper protection against ultraviolet radiation. The specialists emphasized that low quality dark glasses can harm the eyes by causing pupils to dilate while failing to block dangerous solar rays, allowing unfiltered radiation to penetrate deeper into the eye tissue.
