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 3447 reviewsThis was my 4th purchase from Seek Optics. I noticed that the cost of the lenses has increased so I did wait 3 weeks to place my order when there was a 20% holiday discount promotion. The lenses arrived in about a week (I am in Florida) in perfect condition and Seek Optics even included a lens pouch at no extra cost which is very appreciated. I recommend Seek Optics and would purchase from them again.
Exceptional and very quick return of you glasses!
Quality as good as the originals at a fraction of the price.
They fit perfect good quality I will be Purchasing a different color for my husband. Highly recommend purchasing from here.
I have owned a pair oakley sunglasses for many years , they are comfortable but as i have gotten older I was unable to wear them because I have needed to wear prescription lens thanks to Seek I can now wear my oakley glasses again, very happy with them.
Customer service was helpful and the lenses arrived quickly, well-packed and with a few special amenities. They popped into my frames, and voila! I have new sunglasses!
Perfect fit, like the look in my old prescription frames.
Initial ordering was simple supplied the model number and the brand, Pre-paid, Seek Optics sent a mailing label, I then shipped them and in about a week and a half I got my sunglasses back and was very happy with the job they had done…Thank you again Seek Optics
