Sun protection: are we all so sensitive to the sun?

Sun protection: are we all so sensitive to the sun?

With the arrival of summer, you automatically back out your sunglasses. Maybe are you one of those who "fear" the sunlight and you wonder why. Explanations.

Why are our eyes may be hypersensitive to sunlight?

As for those with more sensitive skin, some have eyes more sensitive to light than others, but is not dangerous to the health of their eyes.

Know this: from 40 years we have all become more sensitive to light. This is a consequence of aging of the eye.

A tip: when your eyes suddenly become very sensitive to light, causing discomfort for more than an hour, and disrupting your daily activities, consult a doctor.

Are clear eyes more sensitive than others?

Since your childhood, you are told that you are more sensitive to light because you have light eyes. Well, there would be no real relationship between the color of the iris and sensitivity to light.

What for ? Just because the pigment that colors your iris does not protect the retina from light. Indeed, the iris consists of two main layers and it is quite another pigment, one located just below the first colored layer, which is protective. And this pigment is the same for all, you have the light or dark eyes.

 The causes that increase the sensitivity to light

If you experience sensitivity to light more than usual, perhaps it is related to:

- A cold, a sinus infection or eye which increases the sensitivity over a transitional period.

- Taking antibiotics, antihistamines or medicine against high blood pressure which can cause hypersensitivity to the discontinuation.

- A precursor cataract, corneal edema or disorders of the contraction of the pupil **.

The best is of course to always consult an ophthalmologist.

 this list is not exhaustive

 For the retina is protected, our autonomic nervous system adjusts the size of the pupil permanently to the amount of external light. When it has problems, it can cause hypersensitivity that endures.
