The method according to the invention comprises illumi- nating a sample volume including the ophthalmic lens with a sample light beam which is provided from a light source having a power of at least 2 mW at a wavelength of 1040 nm to 1080 nm and which does not exceed 5 W. In carrying out the method according to the invention an ophthalmic lens is inspected which has been manufactured such that it comprises scattering centers embedded in and/or on an anteri- or surface and in and/or on a posterior surface thereof, respectively, and/or distributed throughout a bulk material being delimited by the anterior surface and the posterior surface of the ophthalmic lens. An interference pattern resulting from a superposition of back-scattered light from the sample volume including the ophthalmic lens and a reference light beam provided from the light source may then be an- alyzed and evaluated.
