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 4033 reviewsI'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.
