They can help if your kid uses screens in the evening. An amber lens for the hour or two before bed cuts the melatonin-suppressing light from phones and tablets, which may make it easier to settle down. It is not magic, but it can take the edge off a screen-heavy night.
That said, a screen curfew and a dim room matter more than any lens. Glasses are not a substitute for limiting late-night screens. If screens are part of the evening, an amber Night lens is a reasonable backup, not the whole plan. Build the habits first, then add the glasses.
