Interlocking engagement between the locking member and lens base prevents focal point drift from vibration.
An asymmetric curved lens design minimizes glare by altering reflection angles, allowing users to switch surfaces for optimal visibility in bright environments.
Segmented retention prevents adhesive failure from thermal expansion while the contact ring protects the lens surface during rotation.
Asymmetric flexible member arrangement reduces optical module height, resolving bulk and weight constraints in image display devices.
