Eye care

Seeing clearly 

  Improve your knowledge about visual health

For Essilor, seeing the world better also means an opportunity to get to know visual health better. This section helps you to understand eyesight problems, their symptoms and solutions for correcting them.

  • To allow you to enhance your understanding in optics, the "Understanding vision" section will introduce you to the main eyesight problems and provide access to a glossary.


  • The eye is a fragile organ which must be treated with care. The "Vision defects" section presents eyesight problems in a broader way and guides you in choosing a solution.

  • Eyesight problems vary according to age and lifestyle. In "Wearers' needs", you can identify them through several user profiles.
