Lens Bubble

The lens vesicle (or lens vesicle) is the rudiment of the lens, which arises as a result of the invagination and detachment of the lens coplacode from the cutaneous ectoderm (the outer layer of the skin). This process occurs during the early stages of eye development in the human embryo.

The lens vesicle is a small bubble containing liquid colloidal material that will later become the lens of the eye. This process begins with the formation of a layer of cells called the lens placode on the inner surface of the eye. It begins to grow and protrude into the eye, forming the rudiment of the lens.

During the development of the eye, the lens placode detaches from the cutaneous ectoderm and begins to grow towards the lens. It continues to grow until it reaches a certain shape and size, after which it develops into a mature lens.

The lens vesicle is an important stage in the development of the eye, since it allows the formation of the rudiments of the future lens and prepares it for further function. However, if this process is disrupted, a number of pathologies can occur, such as aphakia (absence of the lens), cataracts (clouding of the lens) or glaucoma (increased intraocular pressure).

Thus, the lens vesicle is an important stage in the development of the eye, which allows the formation of the rudiment of the future lens. However, if the process is disrupted, it can lead to serious pathologies such as aphakia, cataracts or glaucoma.

**Lenticular (crystalline) vesicle** is the rudiment of the eye in vertebrates, having the shape of a spherical vesicle and containing a substance that is the precursor of the vitreous body. From the crystalline bubble, ciliary processes are formed, from which the lens is formed. The lens grows from the aqueous membrane - the opaque chamber of the eye. The process begins with the formation of a tubercle on the inner surface of this chamber - the so-called lens placode. Until this point, the transparent pupillary structures located inside the aqueous membrane are called lens bulbs.

After the appearance of the placode and the compaction of its internal membranes, six protrusions are formed on its surface, resembling paddle-shaped cartilaginous outgrowths. They are called belts because they resemble wide belts. Two lens capsules of the eye will subsequently appear on each belt. By the age of 3–5 months, there are twelve belts - this is exactly how many lenses there will be in a person’s eye.
