Common Eye Myths Debunked
Post on 19th February 2026
We’ve all heard them – those age-old pieces of advice about eye health that get passed down through generations. “Reading in dim light will ruin your eyes.” or “Eating carrots will help you see in the dark” But how many of these old wives’ tales are true?
At Scrivens Opticians & Hearing Care, with more than 85 years’ experience in eye care, we’re here to set the record straight and debunk the most common eye myths.
Myth 1: Sitting too close to the TV will damage your vision
The truth: Parents have been saying this for decades, but there’s no evidence that sitting close to the television causes eye damage. Children often sit close to screens because they can focus at close range more easily than adults – it’s perfectly normal. However, if you or your child consistently need to sit very close to see clearly, it might indicate short-sightedness, so it’s worth booking an eye test.
Myth 2: Wearing glasses makes your eyes dependent on them
The truth: This is one of the most common misconceptions we hear. Wearing the correct prescription glasses doesn’t weaken your eyes or make them lazy. What actually happens is that once you experience clear, comfortable vision with glasses, you’re more aware of the difference when you’re not wearing them. Your prescription may change over time due to natural ageing processes, but this would happen regardless of whether you wear glasses.
Myth 3: Carrots help you see in the dark
The truth: Whilst carrots are rich in vitamin A, which is essential for eye health, eating them won’t give you the ability to see in complete darkness. This myth actually originated as British propaganda during World War II to explain why RAF pilots were so successful at shooting down German planes at night – the real reason was the development of radar technology, which they wanted to keep secret. A balanced diet that includes vitamin A is important for maintaining healthy eyes, but it won’t transform your vision beyond its natural capability.
Myth 4: You only need eye tests if you’re having problems
The truth: Regular eye tests are crucial even if your vision seems fine. Many serious eye conditions, such as glaucoma, diabetic retinopathy and age-related macular degeneration, develop gradually without obvious symptoms in the early stages. Eye tests can also detect other health issues including diabetes, high blood pressure and even brain tumours. We recommend adults have an eye test every two years, or more frequently if advised by your optometrist.
Myth 5: Using computers causes permanent eye damage
The truth: Extended screen time doesn’t cause permanent damage to your eyes, but it can certainly lead to digital eye strain, also known as computer vision syndrome. Symptoms include dry eyes, blurred vision, headaches and neck pain. The 20-20-20 rule can help – every 20 minutes, look at something 20 feet away for at least 20 seconds. Ensuring your screen is at the right distance and height and remembering to blink regularly, can also make a significant difference.
