If Essilor is Toyota then Crizal is Corolla and Espace (not specs) is Camry. Both these lenses are in use for more than a decade. Avoid buying it locally here in Doha if you are on a tight budget. There is a drastic difference in price as compared to the subcontinent. If you really don't care about the price, check it in Yateem in City Center or Dar Optics. Al Jaber might also have it, not sure though.
