Vitamin A and vision make potent allies. Carrots contain lots of beta carotene and Vitamin A, which can contribute to the health of your eyes and may provide a great source of eye vitamins for macular degeneration and cataracts. Carrots contain lots of Vitamin A and a pigment called rhodopsin. Rhodopsin helps us see in low light situations. Without enough rhodopsin, we wouldn’t be able to see very well at night.
Vitamin C can be found in fruits like oranges, kiwi, and strawberries, as well as vegetables like broccoli, mustard greens and peppers. In addition to providing antioxidants, it can also help slow down cataracts and provide needed eye vitamins for macular degeneration.
Vitamin E can be found in many nuts, like almonds, peanuts, and pine nuts, along with dried apricots and sunflower seeds. This vitamin may serve as a great antioxidant and agent against cataracts and macular degeneration.
Blue light, which emanates from the screens of video games, mobile phones, tablets, computers and TVs, can wreak havoc on your vision. Blue light is harmful to eyes because it has the highest energy wavelength of visible light and this penetrates right through the eyes natural filters, to the back of the eye. This exposure over time can cause permanent damage to the back of the eyes, increasing the risk of age-related macular degeneration (AMD) and permanent vision loss. While blue light can be damaging to everyone’s eyes, children under the age of 18 are especially at risk because their eyes are still developing. Their eyes do not have adequate protective pigments to filter out some of the blue light so the more time they spend staring at screens, the more their eyes are exposed to the harmful effects of blue light without any protective filtering.
The resulting retinal stress from too much screen time causes watery and irritated eyes, blurred vision and headaches. Excessive screen time also contributes to poor sleep because blue light exposure suppresses the release of melatonin, the hormone that tells us when it is time to sleep. The impacts of poor sleep include irritability, fatigue, and reduced capacity to deal with daily tasks such as homework.
Cataracts cloud our eye lenses, making it more difficult to see clearly. This may occur when proteins build up and form a cloudy layer on the lens. This reduces the amount of light that can enter into the eye. A person with cataracts may experience problems driving at night, seeing halos around approaching headlights from other cars. This glare can also cause foggy/misty vision during the day. Cataracts often take long to form, which is why we associate them with the older generations. However, they can develop in those as young as newborns too.
Prevention of Cataracts?
A healthy diet that includes plenty of Vitamin C and E, along with lutein (found in kale, spinach and turnip greens) and zeaxanthin, may help with cataracts. Eating a lot of leafy greens and smoking less or not at all, may help slow down the formation of cataracts.
