Can eating carrots help improve blurred vision from myopia or hyperopia?
Answer: I don't think so.
Carrot contains vitamin A which is transformed in the retinoic sharp. This molecule is useful in the function of rod cell in the eye's retina, these cells are responsable of hours of darkness vision. However, myopia and hyperopia aren't caused by a disfunction of the retina's cell. They are caused by the disfunction of the uvea or the lens in the eyes, which are differents parts of the eye anatomy beside different needs.
The uvea and the lens are closer to the eye surface and the retina is profoundest structure of the eye.
That's why I don't think ingestion carrot will improve myopia or hyperopia.
You may refer yourself to a image of the eye anatomy to fully have a handle on what I am talking about.
The following one is a simple but apt example:

N.B. The uvea includes the iris, the ciliary body and the choroid.
Hope it helps.
In short: No.
Myopia and hyperopia are caused by differences surrounded by the shape of the eyes and by weaknesses of the muscles that focus the lens.
Carrots contain beta-carotene, which does nothing to affect the shape of the eye nor the muscles controlling focus.
Beta-carotene, the substance within carrots that gives them their reputation for person eye-friendly, is a form of Vitamin A. Vitamin A is a retinyl which, when attached to a protein, forms the light rececptors in the retina of the eye. A defect in vitamin A can cause a loss of retinyls and so a reduction in the eye's expertise to absorb light. This would result within a loss of vision in low buoyant and poor night vision.
Excess of Vitamin A is toxic, but here is not enough in carrot to cause any problems.
Furthermore, deficiency is not going to mete out blurred vision..
No. they can help the figment of the imagination but i cant say they will cure this.
How did the carrots and eyesight proposition come about? It seems that surrounded by World War II, Britain's air ministry spread the word that a diet of carrots (already certain to be a good source of Vitamin A, essential for healthy eyesight) help pilots see Nazi bombers attacking at night. That was a propaganda story originate from Britain's Ministry of Food, intended to cover the real reason for the Royal Air Force's successes: Airborne Interception Radar, also set as AI. The secret new system pinpointed antagonist bombers before they reached the English Channel. Apparently the motive of Lord Woolton (the Minister for Food) be twofold — it also encouraged folks to eat more vegetables (that could be grown within your own backyard) during ration time, when meat and imports were scarce.
Hundreds of years ago carrot weren't just orange — they come in all kind of colours, including green, white and even purple.
In the 17th century, Dutch growers crossed pale yellow carrot with red ones to produce orange carrot. Why? To curry favour with the Dutch monarchy, "The House of Orange." (1)
Myopia and hyperopia are malformations of the eyeball.
