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 3774 reviewsExcellent fit. Amazing quality. Superb value for the money. Highly recommended.
I had the replacement lenses within a week of placing the order. It was easy to install them. They were a perfect fit and look great. The visibility with these replacements is better than with the originals, which, after a few years, peeled off. They don't have the Ray-Ban logo, but they are replacement parts. Too soon to tell about the quality, but so far I am pleased.
Very happy with my purchase.
I have dealt several times with SEEK for a variety of Neds from retrofitting lenses to brand new glasses. Their work is excellent. Customer service is as close to perfect as possible. The delivery times are consistent and reliable. I would go no where else for my eyeglasses, especially in the highly specialized designer brands.
I'm not impressed.
Compared to my old lenses these are cloudy and not polerized. Not sure what happened to my order but not impressed
Had to replace the rubber eye-glasses arm covers. New ones fit OK. But they work fine. They were slightly long but no biggie.
Clear view. Happy to bring new life to my JawBones :-).
The nose pieces were as described and fit very well. Fast delivery, great transaction.
I have used seek several times and the professionalism, workmanship and customer service are excellent. They have revitalized many of my expensive frames as my eyesight has changed.
Order came in quick very happy.
The replacement lenses as well as the arm covers and nose pads fit perfectly to save a pile of $ and the Oakley’s!
