Quick answer: No, blue light glasses are not a treatment for seasonal affective disorder (SAD). In fact, SAD is usually helped by getting more bright light, especially in the morning, often with light therapy. Blue light glasses are an evening tool that blocks light, the opposite of what daytime SAD relief needs.
What actually helps SAD
- Bright light exposure, especially morning light or a light-therapy lamp
- Getting outside during daylight hours
- Professional support, SAD is a form of depression and responds to treatment
Where blue light glasses still fit
They're for the evening: blocking blue light at night to protect your sleep, which supports mood generally. Just don't wear heavy amber lenses during the day, you want that daylight. If you think you have SAD, talk to a doctor about light therapy and other options.
The bottom line: Blue light glasses won't treat winter blues, SAD calls for more bright daytime light, not less. Use light during the day (and see a doctor), and keep blue light glasses for protecting your evening sleep.
