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.

I had these great frames but they were prescription. I looked everywhere for non-prescription sunglasses lenses until I found Seek Optics! I had them installed their premium sunglasses lens which turn out awesome at a great price! Thank you Rick Gray
Easy order, fast delivery, replacement looks nice and fit RB frame perfectly.
I've never had transparent lenses before, I was skeptical if they would get dark enough. I'm really impressed, in overcast they darken just slightly, and in full sun they really shine. They get dark pretty quick and no issues in sun all day.
The fit and shade of the sunglasses were as described. I'll use them again in the future.
I have replaced lenses on my Prada and Rayban sunglasses and everything went well 😎
I'm waiting for another set for my other Rayban Wayfarers right now. The price is right and I like the way they look and the dark black tint on the exterior isn't too dark when I look through them. Overall I am pleased with my purchases. Thank you so much for the 40% Xmas specials too! I will always be looking here first when I need to replace any lenses.
Dear Seek,
Please forward my sincere thanks and appreciation to the Technician(s?) who fitted the lenses for these two Raen frames.
Zero slop, noise or free play from the lenses in the frames; virtually indistinguishable from the OEM lenses in regards to their installation.
The professional talent applied to this order exceeded that of most other “concierge” lens services I’ve used domestically and even some I used in Japan. This is particularly impressive considering how busy you must be this time of year.
Whoever decided to make the lenses on the Oakley Flak Draft easily replaceable should win a Nobel Prize (If they awarded one for industrial design). The fact that Seek makes lenses that fit nicely comes a close second. I have several varieties and sometimes take the 2 minutes to swap out some of the specialty lenses for the ones that are the darkest available. Even compared to ones from Oakley themselves. I miss my old pair of Ray-Ban Cats that had both photo and temperature sensitivity. If Seek could work on something similar, it would win my award too.
AS described- sent quickly - fit exactly - Thank you
Snapped easily into place. Glad I didn’t!
The replacement was exact fit n function for my RB4190.
Nose replacement kit was what I ordered, unfortunately it was delivered to wrong address so I ordered another set.
