SOLA commissioned independent study to compare Body Tinted vs. SOLA Dip Tinted:
• COLTS Testing Laboratories
• Dr. Alan Reichow, Pacific University College of Optometry, Forest Grove, Oregon

SOLA lenses proved to be superior in the following categories:
• Drop Ball Test (SOLA = 0 failures)
• Abrasion Test (Bayer) (Superior resistance and consistency)
• Tumble Test (Superior resistance and consistency)
• Haze Average (SOLA 4.5 times LESS Haze)

BODY TINTING Advantages Color durability Disadvantages Optical reduced performances: Haze Plain color (no gradient) Poor coating adhesion Reduced impact resistance

BATH TINTING Advantages Optical Superior performances: no haze Exceptional impact resistance Elevated coating adhesion Big color variety in plain tint and also gradient, double gradient, etc. Disadvantages Lower color durability
