It seems that the question is asking for information on two different topics: green eyes and green cleaning products. Here are the answers to both:
Green Eye Percentage
Green eyes are the rarest eye color in the world, with only 2% of the world population naturally having green eyes. Green-eyed people can have myopia (nearsightedness), astigmatism, or hyperopia (farsightedness), just like people with any other eye color. Green eyes are a genetic mutation that results in low levels of melanin, though more melanin than in blue eyes. People with green eyes are more likely to be extra sensitive to UV rays because green eyes have less melanin than brown eyes.
Green Cleaning Products
Green cleaning products are cleaning products that are designed to have minimal impact on human health and the environment. Using green cleaning products can help to reduce the human health and environmental concerns that come along with cleaning. Here are some characteristics of green cleaning products:
- Minimal presence of or exposure to potentially harmful chemicals, such as: ingredients containing phosphorus or nitrogen, which can contribute to nutrient-loading in water bodies, leading to adverse effects on water quality.
- Low flammability, e.g. flash point > 200 degrees F.
- pH closer to neutral, e.g. greater than or equal to 4 and less than or equal to 9.5.
- Fragrance-free or meets EPA’s Safer Choice Criteria for Fragrances.
- Designed for use in cold water in order to conserve energy.
- The EPA’s Design for the Environment (DfE) Program labels antimicrobial products that have been reviewed by EPA and found to meet both the pesticide registration requirements and the strict environmental and health criteria of the program.
- Products that meet the EPAs Safer Choice requirements for cleaning and other needs are listed on the EPAs website.
It is important to note that even products advertised as "green" or "natural" may contain ingredients that can cause health problems. Manufacturers are not obligated by U.S. law to list all ingredients in consumer products.
