Blu Tech Lenses
BluTech Lenses filter high-energy blue and ultra-violet light using ocular lens pigment derived from the auto-oxidation of 3- Hydroxykynurenine (3-OHKyn). The ocular lens pigment is then combined with melanin and isolated in a durable material. When used in an optical lens, this infusion of pigment provides the same protection, contrast enhancement, and color perception to the eye as the natural yellow-brown coloration of the human crystalline lens.
Available in Indoor & Outdoor options.
Benefits:
- UVA & High-Energy Blue light protection
- Natural depth and color perception
- Improves visual acuity and night vision
- Improves contrast and reduces glare
- Impact Resistant
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.
