"Second eyes": how to choose glasses

Such an important item as glasses appeared in the 16th century. Over the years, glasses have changed a lot. Now it is not only a necessary item for many to correct vision and protect eyes from ultraviolet radiation, but also a fashion accessory that can perfectly complement the image of a person, emphasize his style and personality.

How to choose sunglasses

Sunglasses come in different varieties too. In order not to harm your eyes, certain rules must be followed during the purchase:

• Decide what you need glasses for. If you buy them for every day, it is enough to buy so-called comfortable glasses with plastic lenses, the shade of which is usually no more than 50%. If you go to the sea or a ski resort, you need to choose glasses that bear a certain marking and the inscription UV 400 or UV Protection.
• Never buy glasses from markets and stalls. There are a lot of them out there, but it can be unsafe to wear them. It is better to buy even inexpensive glasses, but in a company store, where they are provided with special markings.
• If you have vision problems, you must first consult with an ophthalmologist.
• The markings of the glasses must be examined carefully. It should indicate how much ultraviolet light the lenses are capable of transmitting. The level of protection is indicated on the liners supplied with quality glasses.

How to choose glasses for vision

The choice of eyeglasses is a very important task. Of course, first of all, a complete examination by an ophthalmologist is necessary. The doctor will conclude what type of impairment you have, whether the deterioration of vision is progressing or it remains at the same level. After that, the doctor gives recommendations on eye exercises, eye care and prescribes suitable glasses.

It is important to take into account the fact that if the deterioration of vision continues, over time the glasses will no longer help, so they will have to be changed every year and a half.

When choosing glasses, two factors are taken into account: the lenses themselves and the frame for the glasses. The frames are plastic and metal. The advantages of plastic include its lightness, but they break faster and may not be suitable for heavy lenses. Metal is a durable material. True, it is quite expensive, but such glasses look more stylish, it is no coincidence that many famous people prefer glasses in a metal frame.

The second important criterion is the lens material. Do not be afraid of plastic: if it is a high-quality material, such lenses have protection against scratches, will last a long time and will not damage your eyes. Glass models are used to correct vision with significant distortion. However, such lenses are easy to break and difficult to replace.

How to choose glasses for a computer

Special glasses are also chosen for working at the computer. Many of us spend most of the day in front of a monitor screen. This, alas, does not contribute to the improvement of vision. Therefore, before purchasing such glasses, it is recommended to have your eyesight checked. Be sure to tell your doctor if you have any discomfort while working with computer equipment, how much time you spend in front of the monitor, and at what distance from your eyes it is usually located.

Having checked your eyesight, the ophthalmologist will determine if you have hyperopia or myopia and, depending on this, will recommend glasses with or without diopters.

In a store, you need to pay attention not so much to design, glasses shape how much on the quality of the frame: on whether the glasses fit comfortably on you, because you will have to spend most of the day in them. Do not hesitate to ask the seller for a hygiene certificate, because your health depends on its availability.

And the most important thing, of course, is the lenses. The type of lenses should be selected taking into account the nature of the activity. For example, if your profession is graphic design, ask a professional to choose lenses that help convey the entire color palette. If you need a computer mainly for games, you should buy glasses with enlightened lenses: they have a special function to reduce glare.

So buying the right glasses is a very responsible business. If you make the right choice, you will give your eyes the protection they need and your face will become even more attractive.
