f.lashes pose little risk of harm. They use a 3V coin battery exactly like those found in most wrist watches and are just as safe.
The LEDs used in f.lashes do not emit any noticeable heat. Our LED lashes are completely cool to the touch.
The LED lashes are weather-resistant. Normal perspiration and weather conditions will not affect it’s functionality.
f.lashes do not interfere with vision. Similar to wearing a head-mounted lamp, the light emitted points outward. You will barely notice the light.
