Expert Optometrist Guide: How to Understand Your Glasses Prescription

Your eyeglass prescription is a written document from your eye doctor that specifies the correction you need for your vision. It contains measurements for both eyes and provides information on the strength of lenses needed to correct refractive errors such as nearsightedness, farsightedness, and astigmatism.

The prescription will typically include the following information:

1. Sphere (SPH): This number indicates the lens power needed to correct nearsightedness or farsightedness. A negative number indicates nearsightedness, while a positive number indicates farsightedness.

2. Cylinder (CYL): This number indicates the lens power needed to correct astigmatism. It will be accompanied by an axis number, which tells the direction of the astigmatism.

3. Axis: This number specifies the orientation of the cylinder needed to correct astigmatism.

4. Add: This number is used for bifocal or progressive lenses and indicates the additional power needed for reading at a close distance.

5. Prism: This may be included if you have eye alignment issues that require prism correction.

It is important to understand that your eyeglass prescription is unique to your eyes and should be filled by a licensed optician or eyeglass provider. If you have any questions or concerns about your prescription, it is recommended to consult with your eye doctor for clarification.
