What is the effect of bringing the temple length-to-bend down?

Bringing the temple length down has the effect of decreasing ear tension. This adjustment allows the frame to sit more comfortably against the ears, reducing pressure and improving overall fit. When the temple is angled downwards, it directs the weight of the frame more evenly along the sides of the head and behind the ears, which minimizes discomfort and the potential for slippage.

This adjustment is particularly important in ensuring that the glasses remain stable while being worn, as excessive ear tension can lead to irritation or fatigue. A proper fit is crucial for both comfort and optimal vision, as it ensures that the lenses are positioned correctly in front of the eyes.
