Abstract

The transmittance of the lens capsule decreases towards shorter wavelengths from around 300 nm. There is a minimum in the transmittance of around 70% at 280 nm followed by a peak of around 75% at 250 nm and then a quick decrease to 2 - 4% at 225 nm. These results were obtained from in vitro measurement of rabbit lens capsules. It is believed that the cyclic amino acids tryptophan, tyrosine and phenylalanine are responsible for the minimum transmittance at 280 nm. It is concluded that the lens capsule efficiently protects the interior of the lens from short wave ultraviolet radiation.
