FAQ – Light therapy lamps and glasses

Here are some frequently asked questions about using light therapy lamps and glasses. I update this page regularly to include questions I receive in my inbox. Happy reading!

Lamp or glasses: which is more effective?

Both are effective when the light intensity is sufficient and you use them consistently. A lamp casts a broader light, while glasses project light directly into your field of vision. Ultimately, effectiveness comes down to how regularly you use whichever device you choose.

How long should you use a light therapy lamp?

A typical session lasts between 20 and 30 minutes at 10,000 lux, in the morning. The ideal duration can vary depending on the lamp's power and your personal sensitivity.

How long should you wear light therapy glasses?

Sessions typically last between 20 and 45 minutes, depending on the model and light intensity. The advantage is being able to wear them while working, reading, or moving around.

Are light therapy glasses as powerful as a lamp?

The raw lux figure is generally lower, but the light is directed straight at your eyes, which makes up for the difference in output.

Can you use both a lamp and glasses together?

Absolutely. Some people use the lamp at home and the glasses when out and about. This helps maintain regular exposure even with a busy schedule. Personally, I now only use the glasses.

Are there any side effects?

They're rare but can include headaches, eye fatigue, or mild restlessness. It's recommended to start with short sessions and gradually increase your exposure time. If symptoms persist, consult a healthcare professional.
