OPHTHALMIC FILTER |
| 摘要 |
An optical device including: an optical substrate provided with selective optical filtering element configured to selectively inhibit transmission, through the optical substrate of at least one selected range of wavelengths of incident light in the visible light spectrum at an inhibition rate of at least 5%, the selective optical filtering element being further configured to transmit at least 8% of incident light of the visible spectrum outside the at least one selected range of wavelengths; wherein the at least one selected range of wavelengths has a bandwidth in a range of from 10 nm to 70 nm, preferably 10 nm to 60 nm centered on a wavelength within a range of between 430 nm and 465 nm. |

1. An optical device comprising:
an optical substrate provided with selective optical filtering means configured to selectively inhibit transmission, through the optical substrate, of at least one selected range of wavelengths of incident light in the visible light spectrum at an inhibition rate of at least 5%, the selective optical filtering means being further configured to transmit at least 8% of incident light of the visible spectrum outside the at least one selected range of wavelengths; wherein the at least one selected range of wavelengths has a bandwidth in a range of from 10 nm to 70 nm, preferably 10 nm to 60 nm centered on a wavelength within a range of between 430 nm and 465 nm. |
