Disclosed is a method for determining a filter for an ophthalmic lens to be placed in front of the eye of the wearer, the filter being able to improve or maintain the visual comfort and/or the visual performances of the wearer. The determination method includes: a step of measuring a variable representative of sensitivity of the eye or both eyes of the wearer to a characteristic light flow, and a step of determining at least one optical characteristic of the filter according to the representative variable measured.

A method of analyzing a visual field of an individual comprises the following steps: —measuring (S) a first visual field (VF) of said individual for a first set of oculo-postural parameters of said individual when said individual performs a first task; —measuring (S) at least one additional visual field (VFi) of said individual for one additional set of said oculo-postural parameters of said individual when said individual performs an additional task; —determining (S) a functional visual space based on said first visual field (VF) and said at least one additional visual field (VFi), said functional visual space being an envelope of said first visual field and said at least one additional visual field. The additional task differs from said first task and/or said additional set of oculo-postural parameters differs from said first set of oculo-postural parameters. A corresponding ophthalmic lens is also proposed.
