Thanks to vision, a person receives 90% of all information about the world that surrounds us. Not everyone is perfect. Some have had problems with it since childhood. Also, due to age-related changes, vision tends to deteriorate. Some people are nearsighted, some are farsighted. For correction, the doctor may prescribe glasses with diopters or contact lenses. What is better - glasses or lenses, we will consider further.
When points are awarded
Glasses consist of a frame and spectacle lenses. They should be selected by an ophthalmologist. This accessory is necessary to improve and correct vision.
What are the indications for wearing glasses:
- Astigmatism. With this disease, objects bifurcate in the eyes, sometimes they are seen curved. Clarity is lost, eyes quickly get tired during work. There may be headaches from overwork. With this pathology, the shape of the cornea or lens is broken.
- Myopia, or myopia. A person does not see distant objects clearly, but well up close. Focusing occurs in front of the retina.
- Hypermetropia, or farsightedness. The gaze is focused behind the retina, so a person sees well in the distance, andclose objects are blurred.
- Aniseikonia. It is very difficult to read, to perceive the ratio of objects. Since the same image has different values on the retina of the right and left eyes. Accompanied by increased eye fatigue.
- Heterophoria, or latent strabismus. The eyeballs have a deviation from parallel axes.
- Presbyopia. Age or senile farsightedness.
Let's consider when a doctor may recommend lenses.
Indications for lens use
Contact lenses use:
- With astigmatism.
- Myopia.
- Hyperopia.
- Disease keratoconus is a violation of the shape of the cornea.
- Lens missing.
- Anisometropia.
Also apply lenses:
- Those who cannot use glasses due to indications due to their profession, such as actors, athletes.
- For the purpose of treating eye diseases.

Contraindications for wearing glasses and lenses
Several reasons why you can't wear glasses:

How to choose glasses
Glasses and contact lenses can only be fitted by an ophthalmologist. They must correct vision.
What is important when choosing points:
1. Choose the right lenses. They can be:
- Single vision. The optical power is the same over the entire surface.
- Multifocal. On the surface there are several zones with different diopters, which pass one into another.
2. First of all, lenses should regulate visual acuity.
3. The doctor examines each eye separately.
4. The interpupillary distance must be correctly measured. This will help avoid additional eye strain.
5. It is important to clarify for what purposes you need glasses:
- To work with a computer.
- Readings.
- Motor transport management.
6. The following parameters must be specified in the recipe:
- Optical power of lenses.
- Interpupillary distance.
- The purpose of the glasses.
Glasses are custom made to order.
The next step is choosing a frame. It can be made of the following materials:
- Plastics or polymers.
- Metal alloy or metal, including gold, silver.
- Combinations of metal with plastic.
A large number of frames allows you to choose the right option for you in accordance with your style.

Choose lenses
Only an ophthalmologist can give a prescription for glasses and contact lenses, as you will not be able to determine the main selection parameters at home. Those for lenses are:
- Corneal curvature.
- Number of diopters.
- Intraocular pressure.
- The work of the eye muscles.
- Peripheral vision.
It is important to consider contraindications.
Lenses are made by:
- From hydrogel.
- Hydrogel with silicone.
Hydrogel perfectly passes oxygen to the cornea. But such lenses are usually designed for one day. The next need to use a new pair.
Hydrogel lenses with silicone are durable. They can be used from one week to six months.
