How to understand if the view is getting worse
Worsening of vision may be due to age, a disease or a genetic predisposition. This problem can be treated with the help of corrective lenses (glasses or contact lenses), drugs or surgery. If you have vision problems, it is important to contact a doctor.
Identify the Symptoms of Vision Loss
1) Note if you squint.
You can do it if you have trouble seeing well. People with vision problems often have eyeballs, corneas or retinas of different shapes. This physical malformation prevents light from entering the eye properly and causes blurred vision. Squinting reduces the curvature of light and increases the clarity of vision.
2) Pay attention to a headache.
This discomfort can be caused by eye strain, which manifests itself when they are subjected to excessive stress. Activities that cause fatigue include driving, staring at the television or computer for a long time, reading, etc.
3) If you See double?
It is possible to see two images of the same object, with one eye or with both. Double vision can be caused by an irregular shape of the cornea, cataract or astigmatism. 14 MAY 2018

4) Note the halos of light.
The halos are bright circles surrounded by sources of light, such as the car’s headlights. Typically they occur in dark environments, for example at night or in rooms without light. They can be caused by myopia, hypermetropia, cataracts, astigmatism or presbyopia. 15 APRIL 2018

5) Notice the presence of flashes.
By day you happen to see a source of light that enters the eye without improving your vision? The flashes can be caused by myopia, hyperopia, cataracts, astigmatism or presbyopia.
6) Do you have a blurred vision?
This phenomenon, which can occur in one or both eyes, is due to the loss of tonicity of the eye, which affects the clarity of vision. It is one of the most common symptoms of myopia.
7) Pay attention to night blindness.
The inability to see at night or in dark rooms is usually made more serious by staying in a very bright environment. It can be caused by cataracts, myopia, certain medications, vitamin A deficiency, retinal problems or congenital defects.

8) Recognize myopia.
This defect makes it more difficult to see distant objects. It occurs when the eyeball is too long or the cornea is too curved and, consequently, the light is reflected in an unnatural way on the retina, causing a blurred vision.
9) Recognize hypermetropia.
This vision defect makes it more difficult to see nearby objects. It occurs when the eyeball is too short or the cornea is not quite curved.
10) Identifies astigmatism.
In this case, the eye cannot concentrate the light in the retina in the correct way. As a result, the objects are out of focus and elongated. The defect is caused by an irregular shape of the cornea.
11) Identify presbyopia.
Usually, this defect occurs with age (over 35 years) and makes it harder for the eye to focus on objects. It is caused by a loss of flexibility and thickness of the lens inside the eye.
Go to the doctor
12) Undergo checks.
Diagnosis of vision problems is performed through a series of tests known as complete eye examination.
To begin with, the visual acuity test is performed to determine the accuracy of the view. You will be seated in front of a board with several letters of the alphabet, of various sizes depending on the row on which they are shown. The larger ones are at the top and the smaller ones at the bottom. The exam tests your vision closely, which is evaluated considering the smallest line you can read comfortably, without straining your eyes.
An assessment of the predisposition to hereditary daltonism is also performed;
Your eyes will be covered one at a time, in order to quantify their ability to work together. The doctor will ask you to focus on a small object with one eye and cover the other. This test allows us to understand if the exposed eye has to refocus the image to see the object. In this case, you may suffer from extreme eye strain and get a “lazy eye”.
Finally, the exam is performed to determine the health of your eyes. For this purpose, the doctor carries out a test with a special light. Your chin is placed on a headrest, connected to this light. The examination is used to analyze the anterior part of the eye (the cornea, the eyelids and the iris) and the inner part (retina and optic nerve).
12) Submit a test for glaucoma.
This disease consists of increased eye pressure, which can lead to blindness. The test is performed by blowing air into the eye to measure the pressure.
13) Get your eyes dilated.
It is normal practice for your eyes to be dilated during the doctor’s examination. This procedure consists in the use of a special eye drop which is able to enlarge the pupils. It is useful for identifying symptoms of diabetes, hypertension, macular degeneration and glaucoma.
Dilatation of pupils usually lasts a few hours.
Wear sunglasses because intense sunlight can be dangerous when you have dilated pupils. The action of eye drops does not cause pain but can be annoying.
14) Wait for the end of the test.
A complete eye exam can take one or two hours. Although almost all results are immediate, the doctor may request further analysis. In that case, ask how long you will have to wait.
15) Get a prescription for eyeglasses.
The choice of lenses is carried out following a refraction test. The doctor will have you try a series of lenses and ask you which one you can see with greater clarity. This exam determines the severity of your myopia, hypermetropia, presbyopia or astigmatism.
16) He wears eyeglasses.
Vision problems are mainly caused by the improper focusing of light within the eye. The corrective lenses help to direct the light on the retina in the right way.
17) Bring contact lenses.
These are small lenses designed to be brought into direct contact with the eye, which float on the surface of the cornea.
You can choose from many different options, such as daily (disposable) or monthly lenses.
Some contact lenses are of different colours and are designed for specific types of eyes. Consult your doctor to choose the model that best suits you.
18) Correct eyesight with surgery.
Glasses and contact lenses are the most used methods by those with vision problems, but the surgical operation is gaining more and more popularity. There are many types of different interventions for the eye; the two most common are known as Lasik and PRK.
In the most severe cases, where the lenses are not powerful enough to improve eyesight, surgery is suggested. In other situations, the operation can replace the long-term use of glasses.
The term Lasik is the acronym of the expression Laser-Assisted In-situ Keratomileusis (in Italian: laser-assisted keratomileusis in situ). This surgery is used to correct myopia, hypermetropia, astigmatism and allows the patient to no longer have to wear glasses. The operation can be performed by all adults who have a prescription for corrective lenses for more than a year. Nevertheless, almost all doctors recommend waiting at least 25 years before surgery, because the eyes change until that age.
The PRK technique is known as Photorefractive Keratectomy, a refractive photorefractory. It is similar to the Lasik technique, as it treats myopia, hypermetropia and astigmatism. The age requirements are the same as for the Lasik intervention.
19) Evaluate if you can undergo drug therapy.
For the most common vision problems (myopia, hypermetropia, astigmatism and presbyopia) drugs are not used. For the more severe ones, your doctor may prescribe pills or eye drops. If you need further treatment, ask your ophthalmologist for advice.
If you have the impression that your vision is getting worse, immediately fix a visit to the eye doctor.
Follow the doctor’s orders.
Find more information about your specific problem.
If you have the chance to undergo surgery, ask what the recovery times are.
If you are prescribed a pharmacological treatment, be sure to ask what the side effects are.
Submit to regular eye exams. A complete eye examination is recommended every 2-3 years before the age of 50. If you are older, go to the ophthalmologist every year.
Consider family history. Your symptoms will be identified first, the results of the cure will be better.
Follow a healthy diet. There are some foods that contain nutrients essential for eye health, such as omega-3 fatty acids, vitamin C and vitamin E. Integrate your diet with vegetables such as cabbage and spinach.
Protect your eyes. Always keep a pair of sunglasses with you. They will help you protect your eyes from the dangerous ultraviolet rays emanating from the sun.
