Dyl had to wear the glasses full time until he was 8 because they say that you can strengthen a childs eye up until that age. His glasses are really thick even though I pay the extra for the thinner light weight lenses, now he's refusing to wear them because he's at that funny age, I know he would wear lenses and tbh id prefer to have him wear the lenses rather than strain his eyes and have them get worse. So if it will help you lo go for it, though I don't know how you'll manage to put the lens in your lo's eye, I wear lenses myself and im still a kinda baby about putting my finger near my own eye lol
