تماما مثل العدسات الشفافة العادية، فإن عدسات ترانزشنز الأصلية تكون شفافة عندما تكون في الداخل أو في فترة المساء. وعندما تكون في الخارج أثناء النهار، واستنادا على درجة تواجد الأشعة الفوق بنفسجية (UV) في الجو، فإن هذه العدسات تتغير تلقائيا لتصبح أغمق إما باللون الرمادي أو بالبني .
هذه العدسات التي تستخدم يوميا تحقق الراحة المتواصلة مع صفاء البال، وذلك بتخفيض الوهج، والتقليل من إعياء العين، وكذلك تقديم الحماية بنسبة UV400 مع كل نظارة .
