Lens suitability depends on individual factors, including prescription, eye health, lifestyle, visual requirements, and professional measurements. Always consult a qualified eye-care professional before selecting or using optical lenses.
If you experience sudden vision changes, eye pain, injury, or another urgent eye-related condition, seek immediate professional medical attention.
