3 Best Plant-Based Foods for Healthy Eyes

EYE – The Amazing Organ

One of the most amazing organs represented in almost every species is certainly the eye. Contains a complex optical system that works similarly to a camera. It reacts to the light and pressure that is reflected from the surrounding environment and converts them in images, creating visual information deciphered in our brain.

The eye is the organ providing us with one of the five fundamental senses we have, giving us the ability to see the world around us.

How sharp can our vision be and how far can a human eye see?

Well, our vision can actually extend far beyond the horizon. Depending on the brightness of the object and its visibility, vision scientists concluded that a person could make out the faint glimmer of a candle flame up to 30 miles (50 km) away or we can perceive bright lights hundredths of miles distant if we are standing on top of a mountain.

But how far away can we perceive an object that is more than just a twinkle of light?

Human-scale objects are resolvable as extended objects from a distance of just under 2 miles (3 km). For example, at that distance, we would just be able to make out two distinct headlights on a car

Because of its incredibly high precision and performance, the eye is one of the most amazing of organs in the body which provide us a vision one of the most fundamental of human senses. All of the muscles of the eye are in constant movement to carry out three simultaneous functions necessary for vision:

  • Exploration of the field of vision.
  • Opening and closing of the pupil according to the light available (diaphragm).
  • Modification of the curve of the lens of the eye according to the distance of the viewed object, thus bringing it into sharp focus.

At the same time, it is performing all of these tasks, the eye continuously sends information to the brain through the optic nerve. It is calculated that while awake, the million or so nerve cells that form the retina send information to the brain at a rate equivalent to 100 Mbps (Mb per second).
Today only the fastest computer networks can match this transmission speed.

Our eyes only needs very little attention.

To carry out all of these complex functions, the eye only needs a small amount of oxygen and several other substances found in foods like vitamins and minerals that are essential for healthy eyes, such as these 3 best plant-based foods for healthy eyes.

carrots
Carrots

1. Carrots:

This root vegetable is crunchy, tasty and highly nutritious and often claimed to be a perfect eye food. Carrots are a particularly good source of beta-carotenes, Vitamin A and antioxidants. Medium sized carrot has approximately a hundred grams and this amount is enough to satisfy our daily needs of Vitamin A.

Vitamin A is necessary for the formation of rhodopsin, the light-sensitive pigment found in the cells of the retina.
It is also necessary for maintaining the conjunctiva (the anterior membrane of the eye) moist and in good condition.
Lack of vitamin A is manifest by a loss of night vision and dry, irritated eyes.

Besides these key facts about eyes benefits, you can find more details in the main article for carrot nutrition facts and health benefits.

Sweet, fragrant fruit with luscious flavour and velvety surface. Good source of Vitamin A, also known as retinol, which is fat soluble allowing our body to easily absorb the nutrients. Apricots contain nutrients that help in improving the eyesight.

Although fresh apricots are grown generally during the summer months, you can get dried or canned apricots at any time of the year. They may also be available in some produce markets during colder months, but likely at a higher cost since they will have been imported. Whichever way you prefer to eat them – fresh, canned or dried – apricots are full of many wonderful vitamins and nutrients that will help you feel healthier on a daily basis.

This fruit provides provitamin A and B group vitamins, which help maintain the delicate conjunctive membrane of the eye in a healthy condition.

Deficiency in vitamins A and B predisposes to dryness of the conjunctiva and fosters or aggravates conjunctivitis.

Did you know that the right proportion of Vitamin A and C and other antioxidants makes apricots number one fruit in slowing the skin ageing process? Here you can read more on how many ways eating apricots can have a positive effect on your health, including the prevention of disease and sickness.
