There are various myths and misconceptions about eye health. Carrots don’t give you better eyesight, wearing glasses doesn’t worsen your eyesight, and sitting too close to the TV won’t harm your vision.
These old myths have been passed down from parents to children for decades. In this article, we’ll talk about common myths about eye health and what’s the truth about them.
Examining these myths can help us better understand eye health. It can also help people make informed decisions about protecting and maintaining vision.
The Myth of Carrots and Night Vision
It’s believed that eating carrots can improve your eyesight. But in reality, it won’t improve visual acuity for people with poor vision or give them night vision.
Here are some facts on this myth:
- During World War II, the British government promoted the carrot myth to mislead the German military and encourage the British public to consume more locally grown produce.
- A 1998 Johns Hopkins study found that vitamin A supplements could reverse poor vision for people with vitamin A deficiency, but carrots still don’t grant people night vision.
- Carrots are rich in beta-carotene, which the body converts into vitamin A. Vitamin A is essential for synthesizing rhodopsin, a pigment that operates in low-light conditions.
- Consuming carrots can restore vision to a healthy person’s baseline level, but it doesn’t enhance vision beyond the normal capacity.
The Role of Genetics and Lifestyle in Eye Health
You might have heard that you don’t have to worry about eye health if you have perfect vision. Unfortunately, this is another myth.
Here are some facts regarding genetics, lifestyle choices, and eye health:
- Genetics plays a significant role in eye health and can predispose individuals to various eye conditions and diseases.
- Having a family history of glaucoma increases the chances of developing the disease by up to 9 times.
- Lifestyle choices, such as smoking, poor nutrition, excessive screen time, and lack of eye protection from UV rays, can exacerbate the risk of developing eye diseases or worsen existing conditions, despite having perfect vision.
Eye Exercises and Vision Improvement
Another prevalent myth is that eye exercises can permanently eliminate the need for glasses or contacts. However, this isn’t true.
Eye exercises can help alleviate eye strain and may improve eye coordination. But they can’t fundamentally change the anatomical structure of the eye or cure refractive errors.
Other Common Eye Health Myths

Many of the myths surrounding eye health have been passed around for generations. Often these are based on misunderstandings or outdated information.
