Which of the following is NOT a recommended option for children's spectacles?

The correct answer identifies semi-rimless frames as not a recommended option for children's spectacles. When selecting eyewear for children, durability and safety are paramount considerations. Full-rim glasses and flexible frames are popular choices because they tend to be more robust, providing better protection for the lenses and reducing the risk of damage during everyday activities.

Plastic frames are also frequently recommended due to their lightweight nature and resistance to breaking, making them suitable for active children. Unfortunately, semi-rimless frames are generally less durable because the lenses are only partially surrounded by the frame, which can increase the chance of lens dislodgement or breakage, particularly in the hands of children who may not handle them with the necessary care.

In a pediatric context, durability and safety of spectacles should be prioritized, emphasizing materials and designs that can withstand the rigors of children's play and daily activities. Thus, semi-rimless frames do not align with these requirements, making them a less favorable option in this situation.
