Today, many people spend a lot of time reading books and using various electronic devices such as a smartphone, tablet or computer. This is not irrelevant as it comes to human’s eyesight.
From this article you will learn which eye defects are most common, how do lenses and corrective glasses work, what is the Bates method and how to improve the eyesight and how to prevent its deterioration in the future.
The Most Common Eye Defects
At present, there are mainly 4 eye defects in the society: short-sightedness (myopia), long-sightedness (hyperopia), astigmatism and presbyopia. Their short descriptions are below:
- short-sightedness (myopia) – a person with such a defect can see well at close range, while the image seen from a distance is blurred; there are also problems with the sharpness of the image seen at dusk; frequent and prolonged use of computers, smartphones and tablets (and reading books in low light) are among the main causes of myopia;
- long-sightedness (hyperopia) – a person with this eye defect can see well from a distance, but has problems with the sharpness of the image seen from close up; long-sightedness, if it occurs, is usually inherited from one of the ancestors;
- astigmatism – this defect is based on the fact that the cornea of the eye is asymmetrical; for this reason, the incident light collapses incorrectly and the picture is not clear; Astigmatism quite often occurs with hyperopia or myopia.
- presbyopia – a defect that occurs with age, caused by the aging of the eye; it is based on the weakening of the image’s sharpness, especially seen from short distances.
Some people may also have color blindness or stereoscopic vision disturbances, but these are disadvantages much less common.
I do not mention eye diseases such as cataracts or glaucoma, because this is an article about eye defects and not eye diseases.
Corrective Glasses, Contact Lenses
This is probably the most commonly used method of “correction” of sight defects. It is not without reason that the word “correction” has been enclosed in quotation marks. Well, glasses and contact lenses usually do not correct your eyesight at all. They just allow you see well when you wear them. After taking them off, you will still see badly.
Nay. Many people say that wearing glasses or lenses can even make your eyes see worse! This is because the eyes get accustomed to the worn glasses and the eyes do not need to strain to see more clearly in the full range of distance. There is a reason why it is often heard that people who wear glasses need stronger glasses after a fairly short time.
Laser Eye Surgery
This is one of the two most reliable methods for improving eyesight, albeit quite costly and associated (like any surgery) with a certain risk. Laser vision correction is performed only in private clinics. The cost of one eye surgery may be various in different countries but it is usually about $2,000.
There are several methods of laser vision correction: LASIK, LASEK, EBK, PRK, TransPRK.
One of the conditions necessary to perform laser eye surgery is the patient’s age above 20 years old. Before the procedure, the patient is given an anesthetic and a sedative.
The entire procedure usually does not exceed 20 minutes.
90%-95% of patients are satisfied with the results of a surgery. However, there is a 1-percent risk of complications during surgery or post-treatment complications.
After laser eye surgery, follow the doctor’s instructions. These include, among others. the need to wear sunglasses with UV filter on sunny days for about half a year after the operation, the need to sleep with the eye band for the first 7 days after surgery and to avoid working on the computer for the first week after surgery.
How To Prevent Eye Defects
As you can see, despite the existence of glasses, lenses and laser vision correction, it is better to blow cold. So how do you prevent potential eye defects?
One of the best methods to prevent eye defects is proper, healthy diet. You may have already noticed that I have been paying a lot of attention to this aspect many times, but it is really important!
The most important vitamins and microelements for improving the eyesight and preventing its deterioration include:
- vitamin A (beta-carotene) – it is a powerful antioxidant against free radicals that damage eyesight; it also improves the functioning of the retinal photoreceptors; the main sources of vitamin A are: carrots, kale, spinach, cabbage, milk, cream, egg yolks, butter;
- vitamin C – improves the synthesis of collagen, which is responsible for the stability of the blood vessels of the eye; supports corneal regeneration; the largest doses of vitamin C include: paprika, orange, papaya, kale, Brussels sprouts, broccoli, blackcurrant, kiwi, strawberries, white cabbage, mango, mandarins, grapefruit, tomato, lemon;
- vitamin E – supports the uptake of beta-carotene; the most vitamin E is found in: vegetable oils (especially sunflower), almonds, margarine, eggs, carrots, nuts, wheat germ, whole-wheat flour, milk, green-leaf vegetables;
- anthocyanins – these are substances found in purple and red vegetables and fruits; they fight free radicals and improve the blood supply to the eyes; the main sources of anthocyanins are: aronia, blueberry, cherries, blackberries, blueberries, red cabbage, red onion;
- B vitamins – they are found mainly in: legumes (peas, beans), cereal products, meat, milk, yeast, cabbage, carrots, soy, mushrooms and potatoes;
- vitamin D – regulates intraocular pressure, supports the prevention of glaucoma; main sources of vitamin D are primarily fish such as: salmon, cod, herring, mackerel, eel; small amounts of it are also found in eggs, milk and cheese;
- The condition of sight can be also improved by taking: selenium, manganese, copper and zinc, which are found mainly in: fish, eggs, nuts, beans, peas, avocados, garlic and onions.
As you can see, taking care of eyesight and preventing its defects and diseases is associated in a large extent with a healthy diet consisting mainly of vegetables and fruits.
In addition to eating fruits and vegetables, it is also worth using vitamin supplements available without a prescription in pharmacies.
How To Improve Eyesight – Eye Exercises, Eye Yoga (Bates Method)
The second important, non-invasive and free method of eye care are eye exercises. They can not only prevent potential sight defects in the future but also correct an already existing (minor) disadvantage.
One of the best websites about eye exercises is https://www.bateseyeexercises.com/. There are exact instructions for performing the exercises and a generator that creates a daily set of exercises based on the time available to the person planning to perform them.
In order to improve your vision and prevent its deterioration in the future, you need about 30 minutes of exercise each day.
Additional information related to the Bates method can be found in the books listed below:
- Aldous Huxley – The Art of Seeing
- William H. Bates – Better Eyesight Without Glasses
Moisturizing Eye Drops
In addition to eye exercises with Bates method, it is also worth using moisturizing eye drops. They are especially important for people working for a long time at the computer and staying in air-conditioned rooms or in the wind.
When looking for eye drops, it is best to choose drops without preservatives. They are available without a prescription at any pharmacy.
If you are working on a computer, you should also remember to take a 5-minute break approximately every hour. At this time, it is worth a moment to rest with your eyes closed or look, for example, through the window to objects in the distance.
If you follow the advices in this article, your eyesight may be in a very good condition for many years. 🙂
