What is the recommended adjustment path to achieve a 45-degree angle at the top of the ear?

• A. From the temple bend to a 45-degree angle at the top of the ear
• B. From the lens to the nose bridge
• C. From the hinge to straight
• D. From the endpiece to the temple tip

Answer: (A)

The key idea is where the bend is made to control how the temple wraps behind the ear. To create a 45-degree angle at the top of the ear, you should start bending at the temple bend and shape the temple behind the ear so that it forms that 45-degree angle. This positioning gives the temple a proper wrap around the ear, helping the glasses sit securely and maintain correct lens alignment. Bending from the lens to the nose bridge changes the front of the frame, not the behind-the-ear angle. Bending from the hinge or from endpiece toward the temple tip doesn’t place the bend where it effectively establishes the top-ear angle, so the desired fit won’t be achieved.
