Objective of FiltersFilter out harmful / distracting light

• UV and/or IR• reflected glare

Transmit useful light

Hi-PO DispensingHi-PO Dispensing

Transmit useful light• preserve contrast• manipulate color perception

– preserve color perception (neutral grey)– alter color perception (all other colors)

ALL filters (except UV) reduce light transmission

Optical clarity is a function of:• transmittance

– perception of white target• color rendering

Superior CosmeticsOptical clarity is a function of:

• transmittance– perception of white target

• color rendering• color rendering– perception of chromatic target

• contrast– ability to perceive contrast near/far

Abbe value is not a major function of clarity• The eye has approximately 1.00D of linear chromatic

aberration (which does not impair vision)– (-10.00 poly lens viewed at 30º produces <0.50D linear

chromatic aberration)

Recommending SubstratesPolycarbonate for Safety

• children• monocular patients• most safety applications


most safety applicationsTensile Strength for Drill Mounts

• 1.60, 1.67• Polycarbonate• Trivex

Higher Index for ThinnessLow Specific Gravity for Lightness

• Polycarbonate• Trivex

SummaryDesign is Fine- with a Fit Devine

• binocularity = width• reduced aberration = contrast sensitivity • customization = potential for > performance


customization potential for performanceIf It Ain't Thermal, It Ain't Durable

• thermal cure = permanent adhesion• conductive layer = anti-static• dissymmetric = hydrophobic

Don't Squint Those Eyes- Polarize!Keep Your Sight With Something Light

• polycarbonate for safety• high index- its great for drill mounts too
