The latest research indicates that climate change affects eye health and can damage vision. This presents a significant challenge for health protection, requiring decisive actions in reducing greenhouse gas emissions. How can we protect ourselves from the harmful effects of pollution and UV radiation?
Climate changes affect our life and health. Recent studies show they are not neutral for vision and increase the number of cases of patients suffering from cataracts, among other conditions. According to ScienceAlert, higher temperatures and increased exposure to UV radiation worsen the condition of this sense and contribute to the deterioration of our physical well-being.
The impact of heat and UV radiation
Rising temperatures on Earth lead to protein damage in the eye’s lens, promoting the development of cataracts and, consequently, vision degradation. Research in Spain has shown that each
A rise in temperature by 0.5°C leads to an extra 370 instances of cataracts per 100,000 people.
Cataracts are a condition marked by the cloudiness of the lens, causing a progressive decline in visual acuity. In severe cases, this can lead to complete loss of sight. Additionally, exposure to ultraviolet rays can harm the eyes, raising the likelihood of conditions like conjunctivitis.

Other hazards to ocular health
Climate changes lead to longer pollen seasons and an increase in mold. This increases the risk of allergic conjunctivitis. In many countries, droughts also cause nutritional deficiencies, affecting the health of citizens, and the lack of a proper diet can damage the optic nerve.

Experts recommend that outdoor workers minimize sun exposure, take frequent breaks, and wear hats and sunglasses with UV filters. It is also important to consume foods rich in vitamins A, C, and E, and to avoid smoking and alcohol. Reducing greenhouse gas emissions is crucial to protecting eye health on a global scale.
