This is a new phrase that I learnt about on Friday after our youngest son had an eyetest at the opticians. Photophobia means you are sensitive to bright lights, which for our son is made worse by his hayfever, asthma and eczema.
During his appointment he spent most of the time rubbing his eyes or blinking and it has now been recommended that he wears polarised sunglasses when out and about. Inside, he often asks for lights to be turned off or to have the blinds closed. If your child has a sensitivity to bright lights it maybe worth investing in a sensory den/pop up tent or let them make a den under the table so that they can shield themselves from the light. This is a popular activity for our son.
