How to Determine Your Segment Height
While it's possible to measure your segment height yourself using a mirror, we recommend enlisting the help of a friend or family member if possible.
- Put on your glasses and stand 8 inches (20 cm) away from the mirror or your friend.
- Face the mirror straight on and hold the ruler vertically between your nose and pupil.
- Align the ruler at the 0 mm mark with the bottom of the lens (IMPORTANT: ensure you measure from the bottom of the lens and not the bottom of the frame).
- While keeping your gaze straight ahead, read the millimeter mark in line with the center of your pupil – that is your Segment Height.
- Repeat these steps 3 or 4 times to ensure accuracy.
Let customers speak for us
from 3675 reviewsSent my frames in for lense replacement with paid postage on their end. Turn around time was fast 7-10 days. Very happy with new lenses.
The best frames for me, thank you Seek optics helping me keep them updated
Ordered polarized grey green replacement lenses for my Arnette sunglasses. I installed the new lenses myself and it was very easy, they fit the frame perfectly. The new lenses are great. They are very clear and the tint is just right. I am very happy with the whole process from start to finish.
I have replaced all my factory lenses with the those from seek optics! 100% times better and clearer than the original lenses!!
Loving my Raybans all over again....thanks to Seek Optics .....
They fit perfectly, these diamond head Mauis have been in my drawer for the last couple years, finally found quality replacement lenses for them. Even ordered another set for my other mauis. Thanks again
My lenses were perfect and easy to install. They kept me well informed during shipping. Swift service.
SEEK optics is the only company I could find who offered replacement lenses for Native Catamounts. These fit perfectly. I doubt OEM lenses would fit any better. I couldn't be happier! Thank you SEEK optics!!
great and perfect fit replacement glasses
