The ciespecagecorr function returns the age dependent ocular spectral transmission correction factors according to CIE S026:2018. Any errors in the data set or in results generated with the Lighting Toolbox are not in the liability of the CIE nor me, see licence.
Usage:
[T,lam] = ciespecagecorr(age,lam)
Where:
| Parameter | Description |
T | Returns the age dependent ocular transmission factors, vector or matrix. |
lam | Specifies the corresponding wavelengths, vector. Default: 300:5:700. |
age | Specifies the age, scalar or vector. |
Plot the spectral ocular transmission correction factors for a 50-year-old observer:
lam = 380:780;
c50 = ciespecagecorr(50,lam);
plot(lam,c50)
grid on
xlim([380 780])
xlabel('\lambda in nm')
ylabel('relative spectral transmission correction')
title('spectral ocular transmission correction - 50 y')
Result:
Plot the spectral ocular transmission correction factors for observers aged 10 to 100 in 10 years steps:
age = 10:10:100;
lam = 380:780;
t = ciespecagecorr(age,lam);
c = colors(length(age));
plotorder(lam,t,c);
grid on
xlim([380 780])
xlabel('\lambda in nm')
ylabel('relative spectral transmission correction')
