Selecting the appropriate sunglass to minimize eye discomfort and maximize visual resolution is a subjective process, dependent upon a personal sense of what ‘helps’.
As a rule of thumb for a successful vision assessment, determining the best filter requires balancing light sensitivity issues with appropriate filter color selection.
For maximized visual acuity, select the highest visible light transmission (VLT) possible. Generally, glare relief is achieved by filtering the short-to-medium wavelengths of the visible spectrum (blue-green-yellow), which scatter within the opacities in the ocular media, and allowing only the longer wavelengths to reach the retina. Commonly known as “Blue-Blockers,” amber and orange filters absorb into the yellow and green ranges respectively.
For glare reduction we have found the following families of colors to be most effective: amber, orange, plum, green and grey.
Contrast enhancement is also a function of reducing the shorter wavelengths, and we have found the following families of colors to be most effective: orange, yellow and amber, all of which have the effect of highlighting visual distinction.
Select the highest possible VLT for enhancing contrast. All UVShield filters block the UV range (UVA, B and C) to 400nm — NoIR filters block 100% UV as well as IR.

PD Measurement
-
Pupillary Distance (PD) or interpupillary distance is the distance between the centers of the pupils in each eye.
-
The industry standard is to measure in millimeters.
-
This measurement is used when preparing to make prescription glasses.
How do I measure my Pupillary Distance (PD)?
- Help from a friend:
- Place a millimeter ruler on the bridge of your nose.
- Have a friend face you about arms length away.
- Have your friend measure the distance between the center of your pupils (the black dots in the middle of your eyes).
- Measure Yourself:
- Look in the mirror while wearing glasses.
- Draw dots on the lenses where your pupils are (using a non-permanent magic marker or highlighter)
- Take the glasses off and measure the distance between the dots.
- Optometrist or Optician:
- Most eye doctors and/or opticians will take the measurement for you in exchange for a very small service fee.
- Guideline:
- Most Adults measure between 55mm -65mm.
- Most Children measure between 42mm - 54mm.
Now you know your PD Measurement!
A valid prescription with PD Measurement is required to order your new prescription glasses.
