Children's spectacle frames should be appropriately sized for comfort, with robust and lightweight materials that won't cause allergic reactions. Frames should fit securely while avoiding pressure points, and include features like spring hinges, large nose bridges, or gel pads for comfort. Sports frames may have strap attachments to ensure secure fit during active play. Early eye exams within the first ten days of life can help detect and treat vision issues early when the eye is still developing. Sunglasses from an optician provide needed UV protection for children's developing eyes.
