Estimating the term…
A system for quantifying the presence of at least one chemical and/or a physical condition in ocular tissues is provided. The system uses a membrane having at least one photo-reactive chemical- and/or physical condition-sensing indicator dye and a photo-reactive reference dye wherein both the photo-reactive chemical- and/or physical condition-sensing indicator dye and the photo-reactive reference dye are responsive to the same wavelength of an excitation light source but emit different wavelengths of light in a light spectrum. An optical data detector receives the emitted light and a processor splits the data into two or more colours of the light spectrum and measures the intensity of the two or more colours. The colour intensity belonging to the emitted light from the chemical- and/or physical condition-sensing indicator dye is compared to the colour intensity of the light emitted from the reference dye and the amount of chemical present and/or the extent of physical condition is ratiometrically determined therefrom.
A system for detecting or assessing a condition in ocular tissues, the system comprising:
A method for detecting a condition in ocular tissues using a smart phone camera, the method comprising:
A contact lens for use in the detection of a condition in ocular tissues, the contact lens having a photo-reactive indicator dye and a photo-reactive reference dye applied thereto to emit light in response to an excitation light source to permit ratiometric comparison based on relative luminescence intensity of different wavelengths of the emitted light, the photo-reactive indicator dye being responsive to the condition and the photo-reactive reference dye being non-responsive to the condition.
