Health experts emphasize that eyesight is our most essential sense, but some common habits might be harming it without us realizing. Vision is responsible for up to 80% of our sensory perception, making eye health particularly important.
While screen overuse is widely known to strain eyes, late 2023 Nielsen data shows that Americans average nearly 60 hours per week on screens, with over 32 hours spent watching TV. Now, two healthcare professionals highlight additional daily habits that could impact our eyes.
Extended screen time
Constant screen exposure from devices like work laptops, phones, and TVs is a primary cause of eye strain. Dr. Jørn Slot Jørgensen from the Laser Eye Clinic London notes that too much screen time can result in dry eyes, headaches, and blurred vision. Limiting screen time and taking breaks is recommended.
Poor lighting
Reading or working in overly bright or dim lighting strains the eyes, making it harder to focus. The Canadian Center for Occupational Health and Safety warns that inadequate lighting can lead to discomfort, burning, and headaches.
Not wearing sunglasses
Skipping sunglasses on sunny days exposes eyes to UV rays. Consultant ophthalmologist Evelyn Mensah from Central Middlesex Hospital advises choosing sunglasses with UV protection. The FDA recommends sunglasses with a UV400 rating to block over 99% of UVA and UVB rays. Mensah also cautions against direct sun exposure, which can damage the macula and increase the risk of eye surface growths.
Ignoring prescription glasses
Mensah stresses the importance of wearing prescribed glasses, clarifying that they don’t harm eyesight but actually help prevent eye strain and headaches.
Poor diet
Eating a balanced diet with the recommended servings of fruits and vegetables provides essential nutrients for eye health, reducing the risk of age-related macular degeneration. Additionally, quitting smoking supports overall eye health.
