(VD=12.00) → This refers to the distance between the spectacle frame and the eye; if it is contact lenses, then VD=0 (unit in mm).
S C A -5.25 -1.00 5 Usually, the at the top indicates the right eye -4.75 -1.25 7 indicates the left eye -5.00 -1.25 10 The non-asterisked parts represent the number of measurements -5.25 -1.00 11 The asterisked parts represent the average value * -5.00 -1.25 10 ----- → This indicates that the right eye has myopia of 500 degrees, astigmatism of 125 degrees, and an axis of 10.
S C A -4.75 -5.00 -0.50 9 -5.00 -0.50 1* -5.00 -0.50 9 ----- → This indicates that the left eye has myopia of 500 degrees, astigmatism of 50 degrees, and an axis of 9.
PD = 62mm Topcon ------ → This is the inter-pupillary distance for both eyes.

More Info

Based on the provided data, it appears that you have myopia (nearsightedness) and astigmatism in both eyes. Let's break down your prescription to understand it better.

Understanding Your Prescription
1. Spherical (S): This number indicates the degree of myopia or hyperopia (farsightedness). A negative value (e.g., -5.25, -4.75) indicates myopia, meaning you have difficulty seeing distant objects clearly. The higher the absolute value, the stronger the prescription needed to correct your vision.
- Right Eye (OD): -5.25
- Left Eye (OS): -4.75
This means your right eye is more myopic than your left eye.

2. Cylindrical (C): This number indicates the degree of astigmatism, which is caused by an irregular shape of the cornea or lens. It is also expressed in negative values for myopic astigmatism.
- Right Eye (OD): -1.00
- Left Eye (OS): -0.50
This suggests that you have a moderate level of astigmatism in your right eye and a mild level in your left eye.

3. Axis (A): This number indicates the orientation of the astigmatism in degrees, ranging from 1 to 180. It tells the optometrist where to place the cylindrical correction in your lenses.

- Right Eye (OD): 5 degrees
- Left Eye (OS): 9 degrees

Summary of Your Vision
- Myopia: You are moderately myopic, with your right eye being slightly more affected than your left.

- Astigmatism: You have astigmatism in both eyes, with the right eye having a more significant degree of astigmatism compared to the left.

Recommendations
1. Regular Eye Exams: Given your prescription, it is essential to have regular eye examinations to monitor any changes in your vision. Myopia can progress, especially in younger individuals, and astigmatism can also change over time.

2. Corrective Lenses: You will need corrective lenses (glasses or contact lenses) to improve your vision. Ensure that your lenses are updated according to your latest prescription.

3. Eye Health: Maintain good eye health by following the 20-20-20 rule when using screens: every 20 minutes, look at something 20 feet away for at least 20 seconds. This helps reduce eye strain.

4. Consider Lifestyle Factors: If you spend a lot of time on screens or reading, consider taking breaks and ensuring proper lighting to reduce eye fatigue.

5. Discuss with Your Eye Care Professional: If you experience any new symptoms, such as increased blurriness, flashes of light, or floaters, consult your eye care professional immediately, as these could indicate more serious conditions.

Conclusion
In summary, your prescription indicates that you have myopia and astigmatism in both eyes, with the right eye being more affected. Regular check-ups and proper corrective lenses will help manage your vision effectively. If you have further questions or concerns about your eye health, don't hesitate to reach out to your eye care provider for personalized advice and treatment options.
