Fact checking the claim “eating carrots improves your vision” I have found this claim to be true. Your claim is supported by an article produced by SCIAM. To factcheck, I went to this article and found it to comprehensively explain the benefits of eating carrots. Vitamin A, of which carrots are rich in, is essential in converting light into brain signals. Furthermore, this helps people to see in low light conditions. Thus, eating carrots can help improve night vision. I trust the source (The Scientific American) because it is a scientific, knowledge-based news source that is “committed to sharing trustworthy knowledge, enhancing our understanding of the world, and advancing social justice” (https://www.scientificamerican.com/page/about-scientific-american)
You also quote a Duke article, and upon going to the Duke Health website, and found that they too confirm eating carrots can help eyesight through its Vitamin A. This article quotes Dr. Jill Koury- and upon researching I found her to be trustable. Healthgrades.com informed me that she has over 42 years in the medical field and is a certified ophthalmologist. Unfamiliar with the term, I found out an ophthalmologist is an eye care specialist.
To confirm all of this, I found another source that corroborates the claim. Gailey Eye Clinic- an eye clinic specializing in LASIK, cataract surgery, and glaucoma- confirms “the vitamins found in the vegetable can help promote overall eye health”. Thus, though carrots may not be able to cure the blind, they are indeed good for your vision.
