Which aesthetic feature might deter parents from buying spectacles for their children?

When considering aesthetic features that might deter parents from purchasing spectacles for their children, semi-rimless frames often evoke concerns regarding their appearance. Parents may worry that these frames, which typically have a more minimalist style and may appear less durable than fully-rimmed options, might not be appealing to their children. The perception that semi-rimless frames could be less stylish or might appear less substantial can lead parents to opt for other styles that they believe are more suitable for a child's use.

In contrast, bright colors are usually attractive to children, larger frame sizes might be necessary for comfort and function, and lightweight materials are often preferred for ease of wear. Each of these features can enhance the appeal of the spectacles to both parents and children, while semi-rimless frames may lack that universal appeal, positioning them as a less favored choice for parents concerned about their child's acceptance and comfort with eyewear.
