SPEX recommends staying within 2 to 3 mm of your current frame size the first two numbers of your frame size. Ex: 52- 16- 145

• 52 = Lens Width
• 16 = Bridge Width (DBL)
• 145 = Temple Length

Lens Height tells you whether progressive lenses will work in the frame. All SPEX accommodate progressive prescriptions.

• Shop Narrow if frames often feel too large for your face
• Shop Average if frames usually feel just right
• Shop Wide if frames often feel too small for your face
