Light brown eyes are a natural eye color and do not require any specific product to maintain or enhance their appearance. However, if you are looking for products that contain ingredients that are safe for the eyes, here are some options:

Positive:

• RefectoCil eyelash & eyebrow tint: This product is designed to tint eyelashes and eyebrows and comes in a variety of shades, including light brown. It contains ingredients such as watermelon extract and antioxidants like lutein that can help hydrate and brighten the under-eye area.

• Natural food colorings: Turmeric and other natural spices can be used to color food products and are safe for consumption. Turmeric is also a great acid/base indicator and can be used in cooking.

Some examples include Sunday Riley Auto Correct, Isdin Isdinceutics K-Ox Eyes, Tata Harper Illuminating Eye Crème, and Dior Capture Youth Age-Delay Advanced Eye Treatment.

It is important to note that some ingredients in personal care products can be harmful to your health. Always read the ingredients list and do your research before using a new product.
