Sunglasses are not only used to avoid glare. Similarly, they also protect the health of the eyes. Consequently, The ultraviolet rays of the sun, and particularly UVA and UVB, are dangerous. Meanwhile, They have toxicity for different eye tissues and can cause eye conditions, in the short or long term. Therefore, “” And you have to be aware that even an indirect sun exposure can have consequences on eye health. Meanwhile, It is not enough to avoid looking at the sun to unsuspected threats eyes be protected “Explains Dr. Consequently, Manon Derrien, ophthalmologist at the National Hospital of 15 – 20 (Paris).
What are the eye diseases caused by the sun? – Unsuspected threats eyes
In the short term. Consequently, UV overexposition can be responsible for:
Acute photokeratitis : « It is an inflammation of the cornea, this transparent part of the eye through which we look. Similarly, Symptoms are red eyes. Consequently, feeling of foreign body, swelling of the eyelids, a decrease in visual acuity and photophobia, very high sensitivity to lightdevelops the Dre Manon Derrien. Similarly, It is reversible in a few hours or even a few days but it is important to consult. Nevertheless, In the meantime, artificial tears, available in pharmacies, can relieve symptoms. And it is important not to wear your lenses! »
Solar retinopathy : More serious, this type of burning touches the retina, at the back of the eye. “” Most often, the unsuspected threats eyes symptoms are not immediate and occur later during the day. Disorders can be irreversible. This condition occurs in particular in the event of direct exposure to the sun (sun fixation).
Repeated exposure to UV can also speed up the appearance of other pathologies. “We are talking about sun capital for the skin. it’s exactly the same for the eyes: cumulative phototoxicity can be responsible for eye and long -term eye pathologies,” says the ophthalmologist.
Cataract : This eye condition concerns an opacification of the totality or part of the lens which alters vision.
DMLA : It is characterized by the appearance of lesions on the central part of the retina, the macula. “” Age -related macular degeneration is multifactorial (age, inheritance, sun exposure, etc.). But we know that exposure to the sun leads to a traumatic renewal of the retina. a deterioration of photoreceptors is an increased risk of DMLA unsuspected threats eyes in predisposed patients predisposed ».
Skin cancer : especially in the eyelids.
Melanomas of the choroid. the conjunctive (membranes of the eye) : It is a rare cancer but of a dark prognosis. “” Sun exposure is the main risk factor for this cancer ».
Pterygion: « It is an outgrowth of the conjunctiva which can even extend over the cornea and cause a visual drop. »
« And. from a strictly aesthetic point of view, people who are exposed without eye protection present more wrinkles, small spots around the eyes », Underlines the Dre Derrien.

Which people are most at risk?
Children are the most vulnerable population group against the sun. “” The lens becomes more and more opaque over time and lets in less and less light. But in children, it is completely transparent. UVs are rushing into it and the light is projected without any filter unsuspected threats eyes on the retina “Explains the ophthalmologist.
People with clear eyes are also at risk. “” In this case. the overexposure to UV is linked to the light color of the iris which let the light come in much more ».
And of course, people with AMD should not be exposed to the sun, nor to blue light.
How to protect yourself?
« It is important to wear sunglasses with large enough. covering glasses to effectively protect rays, regardless of the position of the sun. For adults, a filter 3 is necessary for a light atmosphere in summer, possibly less if the sky is cloudy. For children, a filter 4 is always recommended. This will also be recommended for adults in the event of very important sunshine. under special conditions, on snow in particular and in summer, on water, during nautical activities and even at the water’s edge “Recommends our expert. Please unsuspected threats eyes note, it is not recommended to drive with filters 4.
For the rest. the advice is the same as for the skin: wear a hat, do not expose yourself to the warmest hours and when the UV index is too high.
« I want to emphasize the cumulative toxicity of the sun for the eyes of which the public does. not seem to always be aware. Exhibition in childhood is a significant risk factor in cataracts. pterygion, cancer, and it is essential to protect children “Supports the Dre Manon Derrien.
