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 3640 reviewsPerfect fit for my frames Just as clear or clear than a factory lenses from Oakley
The lenses were as advertised. I ordered 2 pair of different color lenses. Both polarized, one with anti-glare on both sides and one without. The anti-glare does make a difference. They were delivered on time and in good condition.
absolutely amazing replacement lenses for my jewel bow Sherpa sunglasses… Will be buying many more. Thank you so much! Please keep manufacturing this lens
Ashley in customer service was wonderful with a projlem i had and immediately took care of it
I scratched a lens on my Oakley Flak 2.0 XL's and needed to replace them. I shopped Oakley's website and decided to look at other options, and found out here's a lot of them. I narrowed it down by reading reviews on the suppliers then interacted with Seek Optics help line before ordering. They were quick to respond and answered all my questions, so I ordered two pair of replacement lenses. The fitment is excellent and their upgraded optical lens is very impressive. I would not hesitant to purchase again from them.
Purchased these Ray-Ban RB2187 polarized replacement lenses along with others from another manufacturer and these topped them all. The lenses sit in the frames perfectly, and having had polarized lenses before, I could tell how well they worked. Fantastic lenses at a good price. Couldn't ask for more!
The lenses I ordered are great. They are easy to keep clean and the price was amazing. I did have a hard time getting the lenses into my frames but I also had a hard time getting the original lenses out so I am not faulting Seek Optics. I am gonna order more lenses soon, I'm wondering if Seek has reading lenses as well. I will definitely recommend Seek to my associates!
Really enjoyed the extra touches Seek does with their lenses, they come in a sturdy clam shell pouch with extra microfiber cloth and glasses bag. The lenses fit perfectly too and the polarization works fine. I'm not expecting perfection at this price and I'm really happy with the value of the lenses.
These are much better than the ones I have, love the color.
