- ‘Kids don’t know what they don’t know’: Why eye doctors say back to school eye exams matter
Eye doctors emphasize the importance of back-to-school eye exams, noting that children often fail to recognize vision problems that impact classroom performance. The American Optometric Association highlights that 75% of children's vision issues are missed in school screenings, which often overlook close-up vision and eye health. Increased screen time and genetic factors contribute to rising nearsightedness rates, which can lead to long-term eye diseases.
- Major review finds link between early screen exposure and developmental concerns
A major UK review found that screen exposure before age two is linked to developmental concerns, including sleep problems, delayed language, and behavioral challenges. Over 70% of babies and toddlers use digital devices, with some spending hours daily on screens. The American Academy of Pediatrics recommends avoiding most screen time for children under 18-24 months.

Researchers are developing a non-laser, non-surgical vision correction method using mild electrical pulses and platinum contact lenses to temporarily reshape the cornea. Early tests on rabbit eyes corrected nearsightedness in about a minute while maintaining the eye's structural integrity.
