Eye care: A clearer look at blurry eye facts

Does reading in the dark or sitting too close to the television damage your eyes? Or, do carrots give you superior vision?

Here is a look at what’s fact and what’s fiction. “Good vision is vital to the quality of life, but far too many fall for myths that can lead to neglect or unnecessary worry,” says Murray Hewlett, CEO of Affinity Health.

“Whether it’s about screen time, reading habits or food, it’s important to know the truth so you can take proper care of your eyes.”

Myth 1: Reading in dim light will ruin your eyes.

Fact: While reading in low light may cause temporary eye strain and fatigue, it does not cause permanent damage to your vision.

Myth 2: Carrots are the best food for eyesight.

Fact: Carrots are rich in beta-carotene, which the body converts into vitamin A, which is important for night vision. However, for overall eye health, a varied diet that includes leafy greens, citrus fruits, oily fish, and eggs offers broader nutritional benefits.

Myth 3: Wearing glasses weakens your eyes.

Fact: Glasses do not weaken your vision. They correct refractive errors, such as near-sightedness or far-sightedness, allowing for clearer vision. Any changes in vision over time are typically due to the natural progression of ageing rather than the wearing of glasses.

Myth 4: Too much screen time causes permanent eye damage.

Fact: Long hours on digital devices can lead to digital eye strain, with symptoms including dry eyes, headaches and blurred vision, but it doesn’t cause lasting damage. Follow the 20-20-20 rule: every 20 minutes look at something 20 feet away for 20 seconds.

Myth 5: You only need an eye test if you have vision problems.

Fact: Routine eye exams can detect issues such as glaucoma, cataracts, diabetic retinopathy and high blood pressure long before you notice symptoms. Regular screenings help catch silent conditions early, even if your eyesight feels normal.

Are you doing enough to protect your sight?

Access to eye care has improved, but many people still delay check-ups. Skipping routine vision screenings can allow problems to worsen unnoticed, impacting daily life, safety, and well-being.

This is especially critical for children who may struggle in school as a result of uncorrected vision issues and older adults who are at higher risk of serious eye diseases.
