I came across a study: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5233810/
which claims that natural UV exposure can be a protective factor to prevent myopia progression.
However, other sources say that UV radiation causes cataracts and macular degeneration https://www.sharecare.com/health/eye-vision-health/how-uv-coating-eyeglasses-protect
For the record, I have been wearing glasses since 6 years old and they always had UV filters on it. Now my myopia is around -6.
I'd like to ask for advice if UV filter for glasses really worths it? Given people spend most of their time indoors now.
