·THREATS ADDRESSED
Built for four daily pressures.
8h+ daily
Screens & blue light
Long focus distances and reduced blink rates leave the corneal surface unprotected.
UV-A · UV-B
Sun exposure
UVA and UVB stress the conjunctiva and accelerate long-term oxidative load.
outdoor
Sport & wind
Wind, perspiration and dust strip the lipid layer at high exposure rates.
/ B · HOW IT WORKS
Three steps. Every day.
01
Tilt
Tilt the head back, look up. Pull the lower lid gently down with a clean finger.
02
Apply
Place a single drop onto the lower conjunctival sac. Avoid touching the eye with the dropper tip.
03
Resume
Close the eye for ten seconds. Resume normal activity. Repeat up to four times daily.
/ C · FOR YOUR OUTDOOR LIFE
Late-afternoon coast. Salt in the air.
Drop Defence works at the ocular surface — quietly, preservative-free — so the eye can keep up with the day.
