Charlie and Lola (2005)

S3E1 I Really Absolutely Must Have Glasses

Lola is adamant about not getting her eyes checked at the optician's, insisting that she has already assessed them herself and found them to be "quite clever." However, everything changes when Mini Reader shows up at school sporting a stunning pair of glasses that captivates Lola. Suddenly, she's eager to have her eyes examined, convinced that she "definitely needs glasses" just like Mini Reader.
