Become a distributor

Apply as a sales partner for our eye test products

Lang-Stereotest AG works successfully with many distribution partners worldwide.

Suitable distribution partners include suppliers, catalogue providers, online retailers, government institutions, medical organizations, specialist providers in the field of optics and ophthalmology, and medical technology wholesalers.

As a distribution partner, you enjoy the following advantages:

  • Favourable purchasing conditions for our eye test products.
  • Professional product photos for website and print
  • Advertising materials in digital and partially printed form
  • Individual support by phone, chat and email
  • Entry in our online sales database
  • All new partners are introduced in our news

We are looking for new distributors primarily in African states, all of South America and Central America, Turkey, Arabian Peninsula, states in Central Asia, Sri Lanka, Pakistan, Bangladesh, Thailand, Philippines and Indonesia and other so far "light blue" countries of our sales overview online

We do not yet have distributors in many of these regions and countries. The increasing local demand for our eye test products in these countries has so far been ordered from our partners abroad. However, in doing so, local buyers face major disadvantages such as long delivery times, high shipping costs, additional customs fees, and often have to organize the bureaucratic effort of customs clearance themselves.

Take advantage of this unique opportunity to be the first local supplier to promote our renowned eye test products in your country and open up a new market. We will provide you with active support in this.
