Method for determining an optical function of an ophthalmic lens adapted to a wearer
A method implemented by computer means for determining an optical function of an ophthalmic lens adapted to a wearer, the method comprising: a wearer data providing step, during which wearer data comprising at least an indication of the hearing sensitivity of the wearer and an indication of the ophthalmic prescription of the wearer are provided, an optical function determining step, during which an optical function adapted to the wearer is determined based at least on the wearer data.
1. A method implemented by at least one processor for determining an optical function of an ophthalmic lens adapted to a wearer, the method comprising:
obtaining wearer data at least including first information related to a hearing sensitivity of the wearer and second information related to an ophthalmic prescription of the wearer;
determining an optical function adapted to the wearer based at least on the wearer data; and
obtaining optical function data corresponding to the determined optical function for manufacturing the ophthalmic lens consistent with the optical function data.
2. The method according to claim 1 , wherein the wearer data further includes third information related to an impact of visual indication on an understanding by said wearer of a vocal message.
3. The method according to claim 1 , wherein said determining is carried out so that said optical function includes a zone adapted for facilitating labo-facial reading of the wearer.
4. The method according to claim 1 , wherein the first information related to the hearing sensitivity of the wearer is determined by at least an objective type test.
5. The method according to claim 4 , wherein said objective type test is a perception test of a range of tonal frequencies.
6. The method according to claim 4 , wherein said objective type test is a perception test of a range of vocal frequencies.
7. The method according to claim 1 , wherein the first information related to the hearing sensitivity of the wearer is determined by at least a subjective type test.
8. The method according to claim 7 , wherein said subjective type test is chosen among one of the following tests consisting of: an evaluation of speech understanding in a noisy environment a Life Questionnaire concerning hearing in everyday listening situations and a Labo-facial reading test.
9. The method according to claim 1 , wherein said determining further includes selection of an optical function from a set of predefined optical functions based on said wearer data.
10. The method according to claim 1 , wherein said determining further includes determining a transmission function based on said wearer data.
11. The method according to claim 1 , wherein said determining further includes determining a dioptric function based on said wearer data.
12. The method according to claim 1 , wherein the ophthalmic lens is a lens of a pair of ophthalmic lenses adapted for the wearer.
13. A non-transitory computer readable medium comprising one or more stored sequences of instructions that are accessible to a processor and which, when executed by the processor, causes the processor to carry out a method for determining an optical function of an ophthalmic lens adapted to a wearer, the method comprising:
obtaining wearer data at least including first information related to a hearing sensitivity of the wearer and second information related to an ophthalmic prescription of the wearer;
determining an optical function adapted to the wearer based at least on the wearer data; and
obtaining optical function data corresponding to the determined optical function for manufacturing said ophthalmic lens consistent with the optical function data.
14. The non-transitory computer readable medium of claim 13 , wherein the ophthalmic lens comprises at least a zone adapted for intermediate distance vision, and wherein the computer readable medium further comprises one or more stored sequences of instructions, which when executed by the processor, causes the processor to use the at least one zone to increase an understanding by the wearer of the ophthalmic lens of a vocal message.
15. The computer readable medium of claim 13 , further comprising one or more stored sequences of instructions, which when executed by the processor, causes the processor to obtain third information related to an impact of visual indication on an understanding by said wearer of a vocal message, wherein the wearer data comprises the third information.
