This ophthalmic lens has a front face and a rear face, and has: a light cut factor CutLED of at least 20% for wavelengths ranging from 380 nm to 500 nm, CutLED being defined by:

Ophthalmic lens for improving night driving vision and a method for obtaining the same

Method for determining a refraction of at least an eye of a person under specific spectral conditions, the method including: an eye illumination step, during which the eye of the person is illuminated under the specific spectral conditions, the specific spectral conditions being provided by a polychromatic source having a spectrum which is different from the spectrum of a white light source and/or by a chromatic filter positioned before the eye of the person and illuminated by a source; and a refraction determination step during which the refraction of the eye of the person is determined under the specific spectral conditions.

Methods and systems for determining a refraction of at least an eye of a person

The present invention relates to a method implemented by computer means of selecting an optical filtration of an ophthalmic device for a wearer, the method comprising: &#x2014;obtaining wearer's preferences relatively to at least one predetermined type of visual environment comprising multispectral or hyper spectral data; &#x2014;selecting at least one filter: &#x2014;corresponding to said wearer's preferences relatively to said at least one predetermined type of visual environment, and &#x2014;determined on the basis of said multispectral or hyper spectral data.

Method for filter selection

The present invention relates to optical lens for correcting color vision for individuals with color vision deficiency comprising a substrate and an absorbing dye which has at least a minimum light transmission factor at a wavelength ranging from 515 nm to 80 nm that is lower than or equal to 40% and quickly varying transmission around 500 nm and around 595 nm.

Optical lens for correcting color vision

The invention relates to a method for determining a filter for an ophthalmic lens intended for being placed in front of the eye wearer, said filter being capable of improving or maintaining the visual comfort and/or the visual performance of said wearer. According to the invention, this method includes:

Method for determining a filter for an ophthalmic lens as a function of a quantity representing a dynamic sensitivity of the eye of a wearer to a variation in a luminous flux
