Study details
The researchers took cells from the human lens and soaked them in lutein, zeaxanthin, or alpha-tocopherol for 48 hours before exposing them to the oxidizing compound hydrogen peroxide (H2O2) for one hour. They then measured the various markers of oxidative stress, DNA damage, and cell viability.
Results showed that H2O2 significantly increased levels of oxidized proteins, lipid peroxidation, and DNA damage, while such dam
