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.

5 minutes after I popped the new lenses my dog chewed up my glasses. So if I were to rate them, I'd suggest making them less tasty.

These rubber kits are just as good as oakley branded and way cheaper. Like how the nose pads have an L and an R on them so there's no question which one goes on which side.

The lenses were easy to install and it took no time to literally see the difference of my old, worn out lenses. These provide crisp vision with minimal eye strain. Good for the massive road miles I drive.

The lenses were delivered on time and packaged beautifully! However, I purchased the wrong size so I had to return them. I highly recommend this company.

Awesome. Was able to replace the original scratched lenses instead of buying new glasses.
