Myopia Epidemic: Our Eyesight is Failing Fast

Myopia, or short-sightedness, is experiencing an alarming global surge. In the UK, rates have more than doubled among children aged 10 to 16 over the last five decades. Projections indicate that by 2050, approximately half of the world's population may be affected, leading some to label it a 'myopia epidemic'.

While genetics play a role, environmental and lifestyle factors are now considered primary drivers. Increased urbanization means children spend less time outdoors and less exposure to bright light. Conversely, more time is dedicated to indoor activities and near-vision tasks on screens and books.

Experts emphasize the protective benefits of outdoor light. Spending around 90 minutes daily outdoors is now a clinical recommendation for children. This practice can delay the onset of myopia and slow its progression, crucial for preventing more severe vision issues and associated eye health risks later in life.

Beyond lifestyle adjustments, modern optometry offers interventions to slow myopia's progression. Treatments include specialized contact lenses and spectacles, with new low-dose atropine eyedrops recently licensed in the UK. However, these advanced treatments are currently only available privately, raising concerns about accessibility.
