Temple Length ( $B$ )	$145 \, \text{mm}$	Given
Calculation	$FS = \frac{55 + 18 + 145}{3}$	Add and divide by 3
Result	$FS = 72.67 \, \text{mm}$	Average frame size

Example 2: Calculate Frame Size for Lens = 50mm, Bridge = 20mm, Temple = 140mm

Step	Value	Explanation
Lens Width ( $L$ )	$50 \, \text{mm}$	Given
Bridge Width ( $W$ )	$20 \, \text{mm}$	Given
Temple Length ( $B$ )	$140 \, \text{mm}$	Given
Calculation	$FS = \frac{50 + 20 + 140}{3}$	Add and divide by 3
