Can your eyes heal from sun damage?
The eyes can heal after sun damage
, but they may experience some vision changes. Many eye problems caused by sun damage are cumulative, meaning they result from repeated and consistent sun damage over many years. Cataracts, pterygium, and macular degeneration are treatable, but will not resolve on their own.
Would the Earth survive without the moon?
Without the moon,
a day on earth would only last six to twelve hours
