Yes. While older smartphones didn't really have any built-in protections outside of brightness and contrast settings, smartphones have become much smarter about protecting users. After all, if users' eyes feel more comfortable, they'll use their apps for longer periods.
Take full advantage of built-in settings like Night Mode, Comfort View, Night Shift, Digital Wellbeing, and Screen Time to reduce your exposure and protect your eyes when using a smartphone.
While you're busy protecting your eyes, use your smartphone to improve your health. From physical fitness to mental health, your phone can help you feel better.
