Core Insights - Climate change is leading to unprecedented increases in global surface temperatures, with 2024 projected to be 1.49°C higher than pre-industrial levels, marking a continuous trend of record-breaking heat [1] - The health impacts of climate change are significant, with the WHO estimating that by 2030, climate-related hazards could result in approximately 250,000 deaths annually and health costs ranging from $2 billion to $4 billion [2][3] - Climate change is linked to various health issues, including heat-related illnesses, food poisoning, and the exacerbation of respiratory and cardiovascular diseases [3][4] Impact on Eye Health - Research indicates that climate change adversely affects eye health, with rising temperatures correlating with increased cases of cataracts and other eye diseases [7][8] - A study in Spain found that for every 1°C increase in average annual temperature, there is an increase of 371 cataract cases per 100,000 residents [7] - In China, populations experiencing extreme temperatures show significantly higher rates of glaucoma and conjunctivitis [8] Mechanisms of Impact - High temperatures can lead to heat stress, which damages the eye's natural defenses and contributes to cataract formation [10][12] - Increased UV radiation due to ozone depletion can cause direct damage to eye tissues, leading to conditions such as corneal inflammation and cataracts [12] - Air pollution, including particulate matter, negatively impacts tear film quality and can lead to dry eye symptoms and other ocular diseases [13][14] Vulnerable Populations - Certain groups are more susceptible to the eye health impacts of climate change, including children, pregnant women, the elderly, individuals with pre-existing health conditions, and outdoor workers [18][19][20][21][22] - Children are particularly at risk due to their increased exposure to UV radiation and lack of protective awareness [18] - Pregnant women may experience changes in eye health due to physiological changes during pregnancy [19] Protective Measures - Recommendations for protecting eye health include wearing UV-protective sunglasses, maintaining indoor humidity, reducing screen time, and ensuring a balanced diet rich in essential nutrients [23][24][25][26] - Regular eye examinations are advised, especially for those over 50 or with pre-existing conditions [28]
