(From "Amulets", by Carol Andrews, The Ancient Gods Speak, edited by Donald B. Redford, page 13):
"The wedjat ('sound one') also made its first appearance in the Old Kingdom; it took the form of the eye of the falcon sky god Horus. The Eye of Horus was considered the most powerful of protective amulets. Abundant examples with many variant forms and materials have survived from all subsequent dynastic periods."

The examples are so abundant because it is "the single most common funerary amulet, the eye of Horus (wd3.t), [as it] guarantees general health and soundness (wd3.)(From "Magic", by Robert K. Ritner, The Ancient Gods Speak, edited by Donald B. Redford, page 212)

(From Reading Egyptian Art, by Richard Wilkinson, page 43):
"From very early times in Egypt the sun and the moon were regarded as the eyes of the great falcon god Horus, though the two eyes eventually became differentiated - with the left eye (the 'Eye of Horus') often being regarded as the symbol of the moon and the right eye (the 'Eye of Re') being that of the sun. An ornate pectoral, or chest ornament, among the treasures of Tutankhamun depicts the right or solar eye (ill.10, while another depicts the left eye beneath a lunar orb(ill.2)"

Notice in the lunar eye illustration, the lunar god Thoth (Djehuty) is there blessing Tutankhamun
Ra Horakhty is on the other side.

It is Thoth who heals Horus' injured eye, after his "contendings" with the god Set.

(From Wikipedia)
"The Eye of Horus (Wedjat)[1] (previously Wadjet and the Eye of the Moon; and afterwards as The Eye of Ra)[2] or ("Udjat")[3] is an ancient Egyptian symbol of protection and royal power from deities, in this case from Horus or Ra. The symbol is seen on images of Horus' mother, Hathor, and on other deities associated with her. In the Egyptian language, the word for this symbol was "Wedjat".[4][5] It was the eye of one of the earliest of Egyptian deities, Wadjet, who later became associated with Bast, Mut, and Hathor as well. Wedjat was a solar deity and this symbol began as her eye, an all seeing eye."

In the solar eye illustration via Wilkinson, Nekhbet is on our left, while Wadjet, the goddess with the cobra form, is on our right.

In Coffin Text Spell 313 Horus states: "I created my Eye in flame... I made my Eye, a living serpent."

Photo from which I traced for this illustration. We can see Horus to the left of the eye which is producing flames

Wadjet is "the patron and protector of Lower Egypt and upon unification with Upper Egypt,
the joint protector and patron of all of Egypt with the goddess of Upper Egypt.
The image of Wadjet with the sun disk is caller the uraeus."(source Wikipedia)

The following is an excerpt from utterance 570 of the Pyramid Texts:

"This Pepi is the one who has seized the White Crown,
The one upon whom is the tie of the Red Crown;
This Pepi is the uraeus which proceeded from Seth,
The uraeus which moves back and forth;
Restore Pepi to health, restore him to life..."
_The Literature of Ancient Egypt_, edited by William K. Simpson, pages 260-261

White Crown=Upper Egypt
Red Crown=Lower Egypt
Pepi - there were two King Pepi's, Pepi I and Pepi II, cartouches here
