Ultraviolet light has a bad effect on vision, and the need to squint can cause wrinkles around the eyes. To avoid these misfortunes, it is necessary to wear sunglasses. How to choose those from which there will really be an effect?
Glass or plastic?
The lenses of sunglasses can be made of glass or polymer, for simplicity, we can say – plastic. It is generally accepted that the first material is preferable because it speaks about the quality of the glasses in general. Also, it is important to get them from reliable glasses shops as quality is often determined by this factor. However, not all so simple.
- Glasses can simultaneously protect from the sun and correct vision (that is, be with diopters);
- Does not scratch.
- Less likely to buy frankly low-quality goods.
Pros of plastic:
- Less fragile, it cannot be broken – which means that such glasses can be bought even for children.
- High-quality plastic cuts off ultraviolet radiation more effectively and protects the eyes.
- Lighter, large-diameter lenses will not be too burdensome to wear.
- Does not sweat.
But the plastic scratches easily! Therefore, you also need to carefully monitor glasses with plastic lenses, it is better to keep them in a case and not put them next to other objects that can hurt them.
Lens size matters too. Sunglasses should not be too small, because otherwise they will not completely cover the eyes, and therefore fully protect from ultraviolet radiation.
Let’s say a few words about the frame. The metal one is more refined, it is difficult to break it, but at the same time, it can be quite heavy and put pressure on the temples or the bridge of the nose. Plastic frames do not have these disadvantages, but they are easy to break or scratch. In addition, in some models, it may look less elegant.
How much light passes through?
There are several types of sunglasses distinguished by the amount of light they let in.
5 types of sunglasses protection:
- 0 – transmits 80% of the light, suitable for a cloudy day, early spring.
- 1 – transmits 43-80% of the light, suitable for the middle lane and not very bright sun.
- 2 – transmits 18-43% of the light, recommended for our climate, if there is a lot of sunlight.
- 3 – transmits more than 18% of light, suitable for resorts, and coastal areas, where the sun is more aggressive, there is more light.
- 4 – transmits 3-8% of the light, suitable for the sunniest resorts and, mountain hikes, and provides maximum protection for the eyes.
What lens color do you prefer?
In general, you need to focus on your aesthetic preferences, but the color of the lenses affects, among other things, how tired your eyes will be.
- The most neutral colors are grey, green, and brown.
- Orange and red are “aggressive” colors, the eyes get tired of them quickly.
- Yellow – too light for a sunny day, such glasses are only suitable for spring or rather cloudy weather.
When choosing glasses, pay attention to the following nuances:
- Do not be afraid of plastic frames but choose only high-quality expensive glasses. If you are afraid to buy a fake – take it with glass lenses, there is less danger of buying low-quality goods.
- Choose colors that are neutral, so that they do not tire you during the day.
- Choose the degree of protection depending on where and how much you plan to wear glasses.
- A plastic frame is lighter, and a metal frame is sleeker and “more expensive” in appearance. Choose according to your preferred glasses.
