According to a report by the Caribbean Climate Outlook Forum (CariCOF), the Caribbean region is expected to experience extreme weather conditions throughout 2024.
In addition to more intense hurricanes during the wet season, the cooling sea surface temperatures in the equatorial Pacific can lead to warmer conditions during the dry season.
As such, after heavier rainfall and increased air humidity from September to November, several areas, including Belize, Martinique, eastern French Guiana, northern Guyana, Trinidad, and eastern Cuba, can expect intense heat from December to May. Unfortunately, the dry season not only brings about low rainfall and drought concerns but can also affect eye health, as explained below.
The link between dry season and eye health
Firstly, the dry season can be characterized by brighter, more intense sunlight. This means residents and tourists alike in the Caribbean are more exposed to ultraviolet radiation, which numerous studies have linked to an increased risk of developing painful eye conditions. Such conditions include photokeratitis or sunburn of the eyes, eye strain, cataract formation, and glaucoma.
Furthermore, recurrent heatwaves, higher temperatures, and other aspects of an intensified dry season can exacerbate existing eye problems, one of which is dry eye disease. A study published in the journal Frontiers of Toxicology notes that extreme weather conditions, such as a warmer dry season, can increase the severity and frequency of dry eye symptoms, including dryness, soreness, burning, irritation, and more. This observation can be attributed to environmental factors affecting the tear film stability and moisture retention on the eye’s surface.
Since the aforementioned eye conditions can affect overall health and daily functioning, individuals visiting and living in the Caribbean region are advised to invest in eye care in preparation for the dry season.
Eye care tips during the dry season
Wearing sunglasses is one of the most practical ways for Caribbean residents to shield their eyes from more intense UV radiation during the dry season. Even individuals who wear eyeglasses for vision impairments must invest in sun protection, as prescription glasses cannot filter UV rays like sunglasses with 100% UV protection do. In this case, they may consider getting prescription sunglasses, which LensCrafters offers in high-coverage styles like oversized and wraparounds from brands like Ray-Ban, Gucci, and Versace. The retailer also has a virtual try-on tool to ensure the right fit when shopping for sunglasses online.
Since extreme heat in the Caribbean can increase the risk of dry eyes, health experts also highly advise staying hydrated. Drinking hydrating beverages helps keep the eyes hydrated and lubricated, making it crucial to meet the recommended daily levels of fluid intake. Residents and tourists alike can do so by bringing a water bottle and filling it with beverages like water and natural fruit juices. The brands Hydro Flask and Yeti have insulated water bottles in different volumes to help meet specific hydration and lifestyle needs.
Lastly, investing in eye care involves getting regular eye examinations to monitor vision health and detect the early signs and symptoms of heat-related eye conditions like dry eyes and eye strain. The good news is that governments in the Caribbean region have been making an effort to make eye tests more accessible for better eye health outcomes. For example, the health ministry in Guyana has launched a GY$1.8 billion comprehensive eye care program, which enables vulnerable individuals, such as those of low-income backgrounds, to get their eye tests subsidized at participating centers like Miracle Vision Care, Optical Works, and Eye Care Guyana.
In summary, the extreme weather forecast for this year’s dry season urges individuals in the Caribbean to take greater care of their eyes. Through strategies like protective eyewear, hydration, and eye exams, they can reduce the risk of heat-related eye conditions and maintain their long-term eye health.
