I’m considering having transition lenses fitted into my four year old DS new glasses. I’m deliberating is he too young? Will he find it confusing when they don’t change colour fast enough when walking from the playground to the classroom. Or is it a great idea as they will provide all the UV protection & doubles up as standard practical pair of glasses for school & high days & holidays! Any thoughts, suggestions or words of wisdom or indeed if anyone has used them on a young child and has some feedback, I’d love to hear from you. Thanks in advance!
