Lens (2016)

Paige and Damon are two flatmates who decide to embark on a new drug trial for a large and faceless pharmaceutical company in the UK. The two quickly begin to experience confusing and frightening side effects that cause them to drift apart and fight among themselves. They are given only three instructions: take the doses on time, don't leave the apartment, and record a regular video diary. Here is every entry they filmed - we leave you to draw your own conclusions.
