Since I put on these glasses, I have not felt a headache or dizziness. I don't have to worry that I often take them off all day, because the temples and earpieces are made of durable curved rubber. It seems that they will not be easily damaged. They are also very comfortable in my ears. I immediately felt different! My world is warmer. In addition, I can fall asleep faster in bed! It may not work for everyone, but it works for me.
