When a person has high visual acuity it is called 20/20 vision (the distance at which the eyes should read the font size). This means that the person is reading at 20 feet a letter whose size must be read at least 20 feet. But what percentage of the population has this visual acuity?
In recent years there has been an increase in people suffering from myopia, astigmatism, etc. It is believed that one of the reasons is because as technology has advanced, visual health care has diminished due to the extreme use of this tool. And it is that from the little ones to the adults they can stay for hours watching television or the phone screen, thus risking their eyesight.
Sight alone deteriorates as a person ages without the need to acquire a disease. That is, despite the fact that the eyes can withstand the greatest amount of blue light to which they are exposed, they will still deteriorate. By exposing the eyes to these tools without protection, the deterioration processes are increasingly accelerated. Have you noticed lately that you don’t see completely clearly? Do you think you need glasses? In this article, we tell you what are the signs or signs that you should put on glasses as soon as possible.
These are the symptoms that you need glasses
When a person begins to wonder ” should I wear glasses?”” It is probably because you have realized that you no longer see with the same quality and sharpness as before. Wearing glasses is now very normal, the Vision Council of America estimates that more than four billion adults wear glasses around the world, while more than 670 million suffer from visual impairment because they do not wear them.
Signs that may tell you that you need glasses include:
- Double vision.
- Pain or itching in the eyes.
- Eye fatigue.
- Blurred vision (not perceiving details).
- Frequent headache (generally this is due to straining our eyes).
- Trouble seeing at night.
- Poor distance vision or problems calculating distance.
- Squinting (this is mainly because the person cannot focus correctly).
- See halos around the light.
- Difficult to adjust the eyes to changes in light and discomfort.
- Difficulty reading.
In case of noticing any of the mentioned symptoms, it is recommended to consult a specialist. Remember that with early detection, you probably don’t need to use deep grading.
Tips to prevent vision problems
Sleep the appropriate hours according to age, a daily average of approximately 8 hours.
Follow a balanced diet rich in vitamins and minerals, preferably green leafy vegetables and red fruits.
Wear sun glasses to protect against ultraviolet rays and blue light.
Do not spend so many hours in front of electronic devices following the 20-20-20 rule. This means 20 minutes working, 20 seconds of rest, you can see a plant, change the distance of the vision focus, and even close your eyes for a few seconds and then continue 20 minutes of work.
Do not touch your eyes, especially with dirty hands.
Do not use drops without indication of your ophthalmologist. Avoid self-medicating.
Visit your ophthalmologist once a year for a general review.
Remember that your eyes also need essential care to keep them healthy. If you notice the symptoms mentioned above, see your doctor immediately.
