What causes my sister's eye number to increase every year and how can we stop it?

Myopia, or nearsightedness, is often progressive in certain individuals, and its increase can be attributed to a mix of genetic, environmental, and lifestyle factors. Genetics play a role, and if there’s a family history, it’s more likely for the condition to progress. Environmental factors, like prolonged near-work tasks (reading, screen usage), and limited time spent outdoors, contribute too. To slow down progression, it’s recommended to encourage balanced outdoor activities and limit extended close-up tasks. A break every 20 minutes during screen or reading sessions, known as the “20-20-20” rule, can be helpful. Glasses or contact lenses should be worn as required for proper vision correction, but they don’t necessarily stop myopia from progressing. However, specific myopia control lenses or multifocal contact lenses show promise in slowing progression in some children. Medicines like atropine drops at low concentrations might also be considered under an ophthalmologist’s supervision, as studies suggest they can help slow myopia progression. Lifestyle modifications should include reduced screen time, ample outdoor activity, and proper lighting during study or computer work. LASIK can be a safe option later when the eye prescription stabilizes, usually in the early 20s. Deciding on LASIK requires a thorough evaluation by an ophthalmologist to assess suitability—think of it when the prescription is stable for at least a year or two. For now, regular eye check-ups and adhering to these guidelines can help manage the condition.
