Verdict: FALSE.
When the light becomes painful
Normally, the pupil automatically adjusts the amount of light entering the eye. In the case of photophobia, this adaptation becomes abnormally uncomfortable: moderate light can cause discomfort or even pain.
Photophobia may be accompanied by excessive blinking, watery eyes or headaches. It is therefore more of a symptom than a disease in itself.
Several disorders may be involved
It is emphasized that this hypersensitivity can accompany different disorders. It therefore does not make it possible, on its own, to determine the origin of the problem.
Certain vision problems can in particular be linked to a migraine with aura. In this case, they do not necessarily constitute an emergency when they correspond exactly to the person’s usual symptoms.
But a first episode or an unusual change in usual symptoms justifies a preventive consultation.
Pay attention to the associated signs
Sudden loss of vision associated with neurological symptoms requires urgent treatment. It is therefore recommended to note, if possible, the exact time of onset of symptoms in order to facilitate medical treatment.
What to remember
Being very sensitive to light is not necessarily a sign of an isolated eye problem. As with many symptoms, it is its context of appearance and the associated signs that allow its importance to be assessed.
Advice from Doctor Gérald Kierzek
To take care of your eyes, three reflexes are important: protect your eyes from the sun with real UV-filtering glasses, take regular visual breaks in front of screens by looking into the distance for a few minutes, blink often and correct your vision as soon as it tires or becomes blurry. Screens mainly cause dryness, visual fatigue and sleep disturbances if they are used late, rather than direct “destruction” of the retina. It is also better to keep them away from the bedroom in the evening.
