Here's a simple guide on how to read your prescription:
- OD and OS: These abbreviations stand for "oculus dexter" (right eye) and "oculus sinister" (left eye). The information for each eye will be listed separately.
- Sphere (SPH): This indicates the lens power needed to correct nearsightedness (-) or farsightedness (+). A minus sign indicates nearsightedness, and a plus sign indicates farsightedness.
- Cylinder (CYL): This represents the degree of astigmatism correction needed, if any.
- Axis: This number defines the orientation of the cylindrical power for astigmatism correction.
- Add: This is an additional correction for presbyopia or reading glasses. It's the added magnifying power applied to the bottom part of multifocal lenses.
- Pupillary Distance (PD): This is the distance between the centers of your pupils, crucial for accurate lens placement.
Example:
OD: -1.25 -0.50 x 180
OS: -1.50 -0.75 x 175
Add: +2.00
PD: 64 (Right) / 62 (Left)
In this example:
- The right eye has a sphere power of -1.25, a cylinder power of -0.50 at an axis of 180 degrees.
- The left eye has a sphere power of -1.50, a cylinder power of -0.75 at an axis of 175 degrees.
- An additional power of +2.00 is added for reading.
- The pupillary distance is 64 for the right eye and 62 for the left eye.
Let customers speak for us
from 3630 reviewsThe 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.
Got replacement lenses for my Native Catamount. I chose the premium polarized. They are better than the original Native lenses. Arrived beautifully and safely packaged and love the soft lens case/ microfiber cleaning cloth.

The contrail frames Require a lip on the lense to fit in a groove on the frames.
The lenses fit looser than the OE lenses so Ashley sent me another set of lenses a little larger free of charge. The replacement lenses still don't fit properly and pop out easily and the left lens has a gap by the nose piece. At this time I am still waiting to hear back from Ashley to see if we can resolve this. I will update if I can.
UPDATE : After a 3rd set of lenses the optician got the lenses to fit and they are beautiful. Thank you so much Ashley for the great customer service and patience with me. I will recommend Seek to anyone who needs replacement lenses.
