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 3446 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
