Exposure to factors such as chlorine in swimming pools, salt water, strong sunlight, air conditioning and environmental allergens often results in a very common and irritating symptom: <strong>red eyes<\/strong>. Although sometimes this is just passing irritation, on other occasions it can be a sign of a more serious problem.

Common Causes:<\/strong> \ud83e\udd14<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Red eyes, medically known as conjunctival hyperaemia, are a sign of irritation or inflammation. In summer, several factors contribute to this problem:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li><strong>Pool Chlorine and Sea Water:<\/strong>\n<ul class=\"wp-block-list\">\n<li><strong>Cause:<\/strong> Chlorine is a disinfectant that can irritate the surface of the eye and the conjunctiva on contact. Sea salt, although natural, can also dehydrate and irritate.<\/li>\n\n\n\n<li><strong>Symptoms:<\/strong> Red eyes, stinging, itching and dryness.<\/li>\n\n\n\n<li><strong>Risk:<\/strong> Water is not sterile. Bacteria, viruses and amoebae in the water can cause serious infections if they come into contact with the eye, especially in contact lens wearers. \ud83e\udda0<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Intense Sun Exposure (Photokeratitis):<\/strong>\n<ul class=\"wp-block-list\">\n<li><strong>Cause:<\/strong> Ultraviolet (UV) radiation without adequate protection can cause \u201csunburn\u201d of the cornea, known as photokeratitis. \u2600\ufe0f<\/li>\n\n\n\n<li><strong>Symptoms:<\/strong> Red eyes, intense pain (as if you had sand in your eyes), excessive watering and extreme sensitivity to light (photophobia).<\/li>\n\n\n\n<li><strong>Risk:<\/strong> It is an emergency. It can leave lasting damage if not treated in time.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Worsening Dry Eye Syndrome:<\/strong>\n<ul class=\"wp-block-list\">\n<li><strong>Cause:<\/strong> Air conditioning \ud83c\udf2c\ufe0f, wind, general dehydration from the heat and low humidity increase tear evaporation and worsen dry eye symptoms.<\/li>\n\n\n\n<li><strong>Symptoms:<\/strong> Red eyes, a gritty sensation, burning and fluctuating blurred vision.<\/li>\n\n\n\n<li><strong>Risk:<\/strong> Chronic dryness can damage the surface of the eye.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Eye Allergies:<\/strong>\n<ul class=\"wp-block-list\">\n<li><strong>Cause:<\/strong> Pollen (if levels are still peaking), dust, dust mites and contact with environmental irritants can trigger allergic conjunctivitis.<\/li>\n\n\n\n<li><strong>Symptoms:<\/strong> Very red eyes, intense itching (very characteristic), clear watery discharge and a foreign body sensation. \ud83e\udd27<\/li>\n\n\n\n<li><strong>Risk:<\/strong> Persistent discomfort that can affect quality of life.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Foreign Bodies and Abrasions:<\/strong>\n<ul class=\"wp-block-list\">\n<li><strong>Cause:<\/strong> Sand, dust, eyelashes and small insects can get into the eye, especially when it is windy or during outdoor activities. \ud83c\udfd6\ufe0f<\/li>\n\n\n\n<li><strong>Symptoms:<\/strong> Red eye, sharp pain, foreign body sensation and watering.<\/li>\n\n\n\n<li><strong>Risk:<\/strong> If the foreign body is sharp or becomes embedded, it can cause a corneal abrasion or infection.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Eye Infections (Conjunctivitis, Keratitis):<\/strong>\n<ul class=\"wp-block-list\">\n<li><strong>Cause:<\/strong> Viruses (viral), bacteria (bacterial) or fungi. Poor hygiene, contaminated water or improper use of contact lenses are risk factors.<\/li>\n\n\n\n<li><strong>Symptoms:<\/strong> Red eye, discharge (purulent in bacterial cases), itching, pain and blurred vision.<\/li>\n\n\n\n<li><strong>Risk:<\/strong> Some infections can be very serious and threaten your sight if they are not treated quickly. \ud83d\udea8<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Prevention: Keep Your Eyes Clear and Healthy This Summer:<\/strong> \ud83d\udee1\ufe0f<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The best way to avoid red eyes and other problems is prevention. Here are some essential tips:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li><strong>Quality Sunglasses:<\/strong> Essential! \u2600\ufe0f Always choose certified sunglasses (UV 400 filter) to protect yourself from UV radiation.<\/li>\n\n\n\n<li><strong>Swimming Goggles:<\/strong> Always wear them in pools and in the sea to protect your eyes from chlorine, salt and microorganisms. \ud83c\udfca\u200d\u2640\ufe0f<\/li>\n\n\n\n<li><strong>Strict Eye Hygiene:<\/strong> Wash your hands thoroughly with soap before touching your eyes or handling contact lenses. \ud83e\uddfc<\/li>\n\n\n\n<li><strong>Don\u2019t Swim in Contact Lenses:<\/strong> This is a golden rule. Lenses act as a magnet for microorganisms in the water. If it is unavoidable, use daily disposables and throw them away immediately afterwards. \ud83d\udeab<\/li>\n\n\n\n<li><strong>Stay Hydrated:<\/strong> Drink plenty of water. If you wear contact lenses or have dry eyes, preservative-free artificial tears are your best ally. \ud83d\udca7<\/li>\n\n\n\n<li><strong>Avoid Rubbing Your Eyes:<\/strong> If you feel itching or irritation, resist the temptation to rub, as this can make the problem worse or introduce infection.<\/li>\n\n\n\n<li><strong>Physical Protection:<\/strong> In sandy or dusty environments, wear protective glasses or sunglasses that cover your eyes well.<\/li>\n\n\n\n<li><strong>Limit Air Conditioning:<\/strong> If possible, do not point the air flow directly at your face, and use humidifiers.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>When to See Your Ophthalmologist: Warning Signs You Should Not Ignore:<\/strong> \ud83d\udea8<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Although red eyes are sometimes just mild irritation, some symptoms indicate the need for an <strong>urgent eye consultation<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Intense or persistent eye pain.<\/strong><\/li>\n\n\n\n<li><strong>Sudden loss of vision or a significant change in vision.<\/strong><\/li>\n\n\n\n<li><strong>Blurred vision or reduced visual acuity.<\/strong><\/li>\n\n\n\n<li><strong>Eye discharge<\/strong> (especially if it is thick and yellowish or greenish).<\/li>\n\n\n\n<li><strong>Extreme sensitivity to light (photophobia).<\/strong><\/li>\n\n\n\n<li><strong>New or very numerous floaters or flashes of light.<\/strong><\/li>\n\n\n\n<li><strong>A foreign body sensation that does not go away<\/strong> after rinsing the eye.<\/li>\n\n\n\n<li><strong>Red eyes that do not improve<\/strong> within 24\u201348 hours.<\/li>\n\n\n\n<li><strong>Any eye injury<\/strong>, however minor it may seem.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Cl\u00ednica Ram\u00edrez &amp; G\u00e1lvez: Your Eye Care Support This Summer<\/strong> \ud83d\udc96<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At Cl\u00ednica Ram\u00edrez &amp; G\u00e1lvez, we know that healthy eyes are essential to enjoying the summer to the full.
