LIFESTYLE MANAGEMENT
Lifestyle factors influence myopia progression.
Taking proactive steps to modify our behaviours can help delay or reduce myopic development.
SPEND TIME OUTDOORS
Research has shown that 90-120 minutes of outdoor time/day can delay myopia onset. Studies have shown that increased light exposure, such as that driven by the sun, causes pupil constriction and an increase in the depth of focus. Other studies have shown that sun-exposure increases retinal dopamine which inhibits axial length elongation. Remember to be sun smart - hats and sunglasses to be worn when outdoors.
RESTRICT EXCESS NEAR WORK
Studies have shown that close tasks (<30cm) for long periods of time (~ >30 minutes) can significantly influence myopia onset and/or progression. It is imperative to maintain regular breaks from close work to maintain a healthy balance.
MANAGE SCREEN TIME
A significant challenge of screen use is how close digitial devices are held and how long they are used for. Research studies have shown a strong link between dyhe use of digital devices and myopic development amongst children and teenagers. Children under the age of 2 should have no screen time. Those aged 2-4 years should have a maximum of 1 hour of screen time per day. For 5-17 year olds, screens should be limited to 2 hours of recreational use pe day. Excess screen time is also linked to other ocular changes, such as dry eye and digital eyestrain.
