This happens when ultraviolet UV rays from the sun hit your skin. Sunlight isnt the only factor that influences freckles.
Long-term sun exposure is commonly the cause and this also includes exposure to other forms of ultraviolet UV light. Freckles are caused by clusters of melanocytes. Now in some cases the melanocytes melanin spread out evenly and appear something like a tan.
Freckles are due to an increase in the amount of dark pigment called melanin and an increase in the total number of pigment-producing cells called melanocytes. Melanin is what gives your skin its color or pigmentation and it also protects you from the sun. For this reason fair-skinned people are more sensitive to the sun.

This in turn causes melanocytes the pigment-producing cells in your skin to produce more melanin which can darken the freckles on your skin.

In order to protect the skin from the suns harmful UV rays the skin produces melanin which causes freckles to appear or become dark and brown.

Those cells in the body that produce pigment in the skin and hair also grow in the eye called melanocytes. Genetics more people are prone to develop red freckles on arm or face due to genetics. Also known as nevi freckles on the eyes are generally harmless and are not uncommon.
