Glasses are a simple and common way to improve your eyesight. They correct the main visual disorders: myopia, hyperopia, astigmatism, and presbyopia.
When should you wear glasses?
Corrective optics should be used in cases where a person’s own vision is imperfect and causes inconvenience. For example, if you must squint and strain to read a text or watch TV, you should use glasses. They are usually used in the presence of the following deviations:
Myopia
Myopia is a visual impairment when a person sees well near, but poorly at a distance. Myopia can occur in both children and adults. In childhood, this can happen due to the rapid growth and stretching of the eyeball, due to high workloads at school, and many other reasons. In childhood, myopia progresses rapidly. To stop the drop in vision, you need to see a doctor. The ophthalmologist will determine the cause of the deterioration, prescribe the necessary treatment for the child, and prescribe glasses for vision.
Farsightedness
Farsightedness is a deterioration in near vision. It occurs both for congenital and acquired (trauma, eye infections) causes. It can progress quickly, so with the slightest deviation, you should immediately visit an ophthalmologist. The doctor will determine the cause of the violation, prescribe treatment, and correct correction. Lack of treatment can adversely affect eye health and accelerate the deterioration of vision.
Astigmatism
Occurs due to an irregular shape of the lens or cornea, when a partly clear, partly blurry image is focused on the retina. Astigmatism often accompanies nearsightedness or farsightedness but can exist separately.
This visual impairment significantly complicates the selection of correction, as special cylindrical or toric lenses are used. They are difficult to manufacture and often require a period of getting used to. Wearing glasses with astigmatism is not always comfortable, then contact lenses or laser vision correction may be the way out.
Presbyopia
After about 45 years of age, age-related changes occur in the eye, due to which the elasticity of the lens decreases. In such cases, it becomes difficult for the eyes to focus on closely spaced objects, and presbyopia occurs – age-related farsightedness. It appears with excellent vision, and with other refractive errors. In the latter case, it will be associated with myopia or astigmatism.
Do You Need to Wear Glasses Always?
The mode of wearing optical products is selected by the ophthalmologist, based on the individual parameters of the patient’s vision. Glasses for permanent wear are prescribed only in some cases. For example, when without correction the eyes are in constant overstrain. In this case, there is a risk of further deterioration of vision. Therefore, better visit known glasses shops and get yourself pair of glasses for living a normal life.
Cases when glasses are worn constantly:
- High and medium degree of myopia (more than 3 diopters).
- Farsightedness.
- Astigmatism.
- Presbyopia due to nearsightedness.
In the case of astigmatism, farsightedness, and a high degree of myopia, constant correction is needed since it is impossible to see normally without it. Presbyopia also sometimes requires glasses to be worn all the time. If this is not done, unpleasant symptoms will occur headache, fatigue, redness, and dry eyes. Lack of correction for severe visual impairment can cause overexertion, headaches, and loss of vision.
If a person does not want to constantly use the correction, but it is required according to indications, he is allowed to use contact lenses. However, they are not suitable for everyone and have more contraindications. Your doctor will help you decide whether to wear glasses or not.
What kind of vision you need to wear glasses depends on the person’s need for clear vision. You can use time correction even for the smallest deviations.
