The formation of a clear image on the retina requires perfect functioning and the integrity of all the ocular structures involved in the vision process.
Before reaching the retina, the light rays coming from the outside have to cross the cornea, the aqueous humor, the lens and the vitreous humor, which act as refractive media, that is, they divert the trajectory of the rays and make them converge. at a point on the retina where visual acuity is highest (yellow macula).
All the rays that fall on this point are seen with great clarity, while those that fall on peripheral areas of the retina provide less sharp images the greater the distance between said areas and. the yellow macula
In principle, the refractive power of the elements that make up the optical system of the eye is invariable, except in the case of the crystalline lens, whose elasticity allows it to adopt more or less spherical shapes to modify its refractive capacity and focus the image on the retina. according to the distance at which the observed object is located (accommodation mechanism).
Any structural change that alters the shape, transparency and functioning of these structures can, therefore, modify the total refractive capacity of the eye, causing a distortion of the image projected on the retina that is manifested by blurred vision of the eyes. objects.
This visual defect can be caused by corneal malformations or injuries (inflammation, trauma, ulceration, scarring, curvature abnormalities); lens disorders (waterfalls), of the ciliary muscle or the iris; variations in the shape of the eyeball, due to anomalies of the curvature of the lenses of the eye or disorders of the accommodation mechanism (myopia, farsightedness, astigmatism, presbyopia); retinal lesions (retinitis, retinal detachment); glaucoma etc
Other factors not directly related to vision such as anxietymultiple sclerosis, alcoholism, diabeteshypoglycemia and allergy, too, can cause blurred vision.
Sometimes blurred vision appears, without an organic cause that justifies it, in people subjected to an intense effort of sight.
Below are several home and natural remedies when blurred vision is caused by eye strain, allergy, or anxiety.

recommendations
Blink the eyes 15 times in a row to increase circulation in the eyes.
Avoid smoke and being exposed to its smoke. Likewise, it is convenient to be away from radiation, such as the sun, microwaves, x-rays, etc.
Avoid rubbing your eyes (even with closed eyelids) when you have blurred vision.
Questions and answers
Is it true that vitamin A is very beneficial for eyesight?
Vitamin A is essential for correct vision, since it is used by the cones and rods for the synthesis of their light-sensitive chemicals.
Its deficiency determines a deficit of such products, especially rhodopsin, a photosensitive substance in the rods that facilitates vision when the light intensity decreases, and, as a consequence, can cause a Night blindness or difficulties adapting vision to darkness or low light. However, these disorders appear when the vitamin deficiency is very pronounced, a situation that only occurs in states of great starvation, in very debilitating diseases or in certain digestive disorders. The lack of vitamin A can also cause visual defects due to involvement of the cornea and conjunctiva, even causing total blindness.
Is it true that abundant consumption of alcoholic beverages causes double vision?
Yes. Alcohol affects the general coordination of the body’s muscles, including those that move the eyes, and its abundant consumption can cause an abnormal deviation of the eyeballs that determines double vision of objects. This effect is especially notable in those people who, due to suffering from a weakening or disorder of the ocular muscles, have a tendency to avert one or both eyes.
