What is Eye?

The eye is a spherical organ in the eye pit, with a large size of the ball.

The eye consists of a combination of three layers which are suitable for passing light and breaking. The outermost first layer is called “hard layer” or “eye aya; this layer forms the transparent layer. The hard layer, which is white and stranded, is a true membrane protecting the eye. A multi-stranded connective tissue, the vascular layer, with the painted cell cover on both sides, the eyeball becomes a complete dark room. In the anterior part of this is the lashy muscles and the cilia region; The small pyramid-like protuberances that fill the blood to keep the hanging bond of the multi-stranded region of the eyelash region are called olan lash extension in.

As an extension of the eyelash area, the vein layer in the anterior section creates a diaphragm (pupil) in the middle of the center by changing the color (iris). The color-changing human iris encompasses the muscle strands to fascinate or diminish the pupil: the irradiated muscular strands provide the widening of the pupil, the strings of the iris sphincter muscle, the constriction of the pupil.

The third and very thin web layer of the eye is a sensitive layer. The middle pit, the whitish small bubble (vision nerve disc), located at the back of this, is the place where the vision nerve enters and is called the ası blind spot Bun. A little beyond the blind spot, the yellow dot is located; this is the sight zone where the external images are best formed.

The nerve of the eye entering the back pole of the eye spreads as many nerve wires towards the catheter and ends with three layers of arrayed neurons. The neurons in the first layer (multi-pole neurons) drive the roller axis in the visual nerve; the anterior extensions connect with the bipolar neurons of the second layer; The neurons of the second layer also coincide with the cylindrical axes of the vision neurons of the third layer. This layer includes cones and rod-shaped neurons, one end entering the red portion of the web layer. The free ends of the cones and rods are directed towards the vessel layer: the rays of light coming into the vein layer break and affect the nerve endings of the stem cells.

What does ”look“ in the dictionary mean?

1. Good or bad qualifications, passions, viewpoint describing emotions; images detection, vision ability.
2. Each compartment of something that has been entered, placed in the other, with sections; (in some idioms).
3. The organ for seeing, the organ of sight; point of view.

Our eyes have the ability to see both far and near clearly in their forties. But after these ages, the ability to see the nearer gradually deteriorates. It is therefore necessary to use the glasses to see the relative after this period.

In patients with myopia, the problem of seeing a relative may start at a later age. Some cataract types may have temporary improvements in patients with a near visual impairment.

Glasses are widely used in treatment. Although some surgical methods other than glasses were applied, they were not very successful yet. The same applies to laser treatments. Contact lenses are another alternative that can be used in the treatment.

What are flying objects?

There are black dots in the area or the feeling of a fly. This blackhead moves wherever it judges. They are more pronounced when looking at white and flat places.

What are the reasons?

There is a transparent liquid called vitreus in our eyes. If the liquid begins to lose its transparency and breaks away from the adherents, a layer of an onion skin is formed. Because of this layer, we see that there are floating objects in the place we look at. Objects may be seen in retinal detachment and tears, tics, migraine and sudden blood pressure changes.

Which Infections Can Be Counted As A Sign Of Disease?

The sign of a flying object is often an innocent symptom and does not require any treatment and is lost over time. However, it may be serious in the following cases:

Sudden thriving

Flies with visual acuity, visual field narrowing, pain, redness may be serious and require an ophthalmologist’s examination. In case of retinal tears, retinal detachment and uveitis, eye examination is required. If no disease is detected, treatment is not necessary and complaints decrease over time.


Complaints such as light flashes or lightning flashes are common complaints in older ages and are often innocent and non-hazardous. However, they may sometimes be indicative of serious diseases such as retinal tears or retinal detachment. That’s why;
