In ophthalmology, "crystals behind the eye" typically refer to the presence of deposits or crystals in the vitreous body, which can occur due to various conditions, such as vitreous syneresis or retinal disorders. These crystalline deposits may be composed of calcium, cholesterol, or other substances, and can lead to visual disturbances. Their presence may be assessed during a dilated eye examination, and treatment options depend on the underlying cause and severity of symptoms.

Sugar crystals behind the eyes are not a common medical condition. It is possible that you may be experiencing corneal arcus, which can give the appearance of a whitish or gray ring around the cornea due to lipid deposits. It is important to consult an eye care professional for proper diagnosis and treatment.

Extrusive igneous rock consists of mineral crystals that are not observable with the naked eye. Obsidian is an extrusive igneous rock (volcanic glass) where there technically are no mineral crystals.
The lens in your eye is located behind the iris, in the front part of the eye just behind the cornea. It helps focus light onto the retina at the back of the eye, allowing you to see clearly at different distances.
The retina is behind the eye The vitreous humor.

Igneous rocks that have mineral crystals easily seen with the unaided eye formed from slow cooling and crystallization of magma deep underground or at the Earth's surface. The slower the cooling process, the larger the mineral crystals can grow, resulting in rocks like granite and diorite with visible crystals.
Rocks that contain crystals exhibit a coarse texture. The crystals within the rock are generally large enough to be seen with the naked eye, giving the rock a grainy appearance.
The water evaporates but the salt does not. This leaves behind crystals of salt on the surfaces.
