10 Yellow Fever Symptoms
3. Light Sensitivity
If you go from a dark room to a lighter room then it will take a short while for you to adjust. Walking into a brighter room would mean that, all of a sudden, there is too much light flowing into your eyes. Our irises quickly adjust accordingly to help prevent too much light from entering the eyes where it might otherwise do damage.
Some diseases can cause people to become more sensitive to light than usual, however, one of which is yellow fever. The patient can find the light levels uncomfortable even when they are not in a particularly bright room. They may need to keep the curtains drawn at all times, and they might also wish to wear dark glasses.
