Quick Answer
Blue light lenses filter high-energy visible (HEV) light from screens. They may reduce eye fatigue and improve sleep when used in the evening — they are not a substitute for prescription accuracy.
Benefits
- Less digital eye strain during long screen sessions
- Reduced glare from monitors and phones
- Optional anti-reflective + blue light stack for office workers
Limitations
- Do not prevent myopia progression alone
- Not required for all prescriptions — personal preference
- Pair with regular eye exams for best vision health
