From Lab to Market: How Eye Sprays Are Tested (Behind the $2.7B Industry)

Focus: Manufacturing science of Blue Light Protection Eye Spray

Step 1: Particle Size Engineering

• Ideal mist: 15-25μm droplets

• Nano-mists (<10μm) risk lung inhalation

• Testing Method: Laser diffraction analysis

Step 2: Preservative Stress Testing

• EU Protocol: 28-day challenge with S. aureus/P. aeruginosa

• FDA Requirement: <10 CFU/ml after contamination

Step 3: Human Repeat Insult Patch Test (HRIPT)

• 200+ volunteers exposed to 10 consecutive applications

• 2024 Standard: ≤5% incidence of irritation
