Show Answer Key & Explanations Step-by-step solution for: How To Measure Your Pupillary Distance (PD) | Zeelool Optical
The image shows a ruler with markings from 0 to 80, and two icons below it: an eye and a smile. There are dashed blue vertical lines extending downward from the ruler to each icon.

Let’s analyze the task:

1. Ruler: The ruler has major markings at every 10 units (0, 10, 20, ..., 80) and smaller tick marks between them, likely representing single units.

2. Eye Icon: The dashed line from the ruler points directly to the center of the eye. Looking at the ruler, this line aligns with the 10 mark.

3. Smile Icon: The dashed line from the ruler points to the center of the smile. This line aligns with the 60 mark.

Interpretation:


This appears to be a visual puzzle or measurement task where you're asked to determine the positions of the two icons on the ruler.

Solution:


- The eye is positioned at 10 on the ruler.
- The smile is positioned at 60 on the ruler.

Final Answer:


- Eye: 10
- Smile: 60

If the task was to find the distance between them, it would be:
60 - 10 = 50 units

But based on the image alone, the most direct interpretation is identifying their positions.

Answer: The eye is at position 10, and the smile is at position 60.
