Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Contact lenses modify the structure of the tear film by biophysical and biochemical interactions. These changes may explain more common dry eye symptoms and may sometimes cause lens failure or discontinuation.

In recent years, the investigators have various objective non-invasive methods of tear film evaluation such as the non-invasive break up time, interferometry, and tears meniscus height. These measurements are performed in clinical practice during consultation by devices such as LACRYDIAG.

The improvement of lens comfort requires a better knowledge of the ocular surface in patients with contact lenses. But currently none of these objective parameters have been accurately described.

Therefore, the investigators would like to build a database to describe the different parameters of ocular surface in patients with soft contact lenses.
