In This Article, We Will Explain, How to Choose Quality Sunglasses, Which Are Suitable for You
Good sunglasses are an accessory of paramount importance, like a watch or a favorite hat. Glasses help to hide the consequences of a hard Friday, they protect the eyes on a clear day, add a double portion of style to the image and even save the stars from annoying paparazzi. In everyday life, Branded Sunglasses in Pakistan are indispensable not only in the warm season but also in winter, because the glare of snow is dazzlingly bright, which is why our eyes need additional protection even more.
Many ophthalmologists consider it necessary to wear glasses in cloudy weather because nowadays it is possible to choose several pairs at once: dark, translucent, with colored glasses, for any shape of face and wallet. Three important criteria: they must provide protection from the sun, is right under your face shape and be strong enough, to last for as long as possible.
We Select Correctly
Material
In good sunglasses, frames and lenses are made of those materials, which prevent the harmful effects of ultraviolet radiation, so it is important to beware of counterfeit fashion because they can worsen vision. It is important to choose Sunglasses in Lahore by the quality of the material as a whole and not by the color of individual elements. For example, plastic ( acrylic, polycarbonate) resists penetration rays, A and B on the retina. In addition, plastic glasses are safe when driving a car: during an accident, their glasses will either fly out immediately or break, but with minimal risk of injury, unlike glass.
The frame can be almost anything: wooden inserts are stronger than plastic, metal arms are also quite durable. It is important to determine the distance to which the lenses are attached to the frame so that in the event of a fall or too strong fixation, cracks do not occur and the glass does not fall out from the slightest impact.
Color and Degree of Blackout
Too dark sunglasses only damage your eyesight: behind the most darkened glasses, the pupils expand involuntarily and become more susceptible to the flow of ultraviolet rays. It is better to choose glasses- "chameleons" or not too dark models.
- Green or gray does not distort color, they can be worn everywhere in any weather.
- Golden yellow block the blue color, they are best worn on cloudy days.
- Polarized glasses are ideal glasses for very bright light, they should be taken on a trip to warm countries or to relax in a ski resort.
- Mirrored - reflect light, suitable for hiking in the mountains and other leisure activities at high altitude.
- "Chameleons" ( photochromic) - change color, adjusting to lighting, can be worn everywhere.
- Graduated - half darkened, suitable for daily wear and car driving.
Type of Sun Protection
An equally important criterion when choosing the right sunglasses is the type of radiation protection. To choose quality sunglasses, you need to understand, how hard work of their protection filter. There are 5 protection categories in total:
0 - minimal protection, it’s more like an image story, but not glasses from the sun, they transmit up to 80% of the light.
1 - medium protection, from 43 to 80% of the light, all the same, accessory case.
2 - miss from 18 to 43%, quite often presented on the shelves of the mass market.
3 - just those sunglasses, which really prevent the harmful effects of ultraviolet radiation.
4 - the highest level of protection that is suitable for the harsh southern sun.
Type of Coating
Polarization coating - is a filter, which blocks the glare and reflections, the brighter the sun, the higher should be the level of polarization of your points. You can check the quality of sunglasses in the store itself using a smartphone: point a white background at the lenses at maximum brightness. Lenses should darken to an opaque state.
A photochromic coating turns glass into "chameleons" depending on the degree of illumination. When light enters the lens, they darken, so these glasses can also be worn in the dark, as they become transparent without exposure to sunlight.
Label
The label will tell about many things, for example, that, what type of glass in the sunglasses, of which the lenses are made, some degree of protection from UV rays. The barcode must be indicated on the label, which is useful in case of exchange or return, brand name, and model, manufacturer. It’s better not to save on the quality of the product: in order to choose good sunglasses in Pakistan, get ready to spend money.
We Select Sunglasses According to the Shape of the Face
In addition to comfort and benefit, I want correctly selected sunglasses to look stylish. If you doubt that, whether you are fit to choose glasses or trying to acquire them remotely, resort to a simple test. To do this, you need to determine your face shape. For example, glasses that are too massive will enlarge the already wide face even more, and models with a thin frame will obviously be lost on the face with bright features.
- The round face type with almost equal proportions must be lengthened and sharpened, and for this, square or rectangular lenses are the best fit. In this case, rounded and oval patterns should definitely be avoided. Take a closer look at sunglasses with wide geometric arches.
- Large rounded sunglasses with a dark or bright rim and a low jumper will fit a square face with a heavy chin.
- The “ cat's eye” shape is suitable for triangular faces, not making the lower part heavier. And glasses with a rectangular shape enhance the effect of facial asymmetry.
- Owners of oval faces are any model of glasses, it is only important to choose the right size. It is worth paying attention to the “aviator” sunglasses.
- For elongated faces, there are many suitable models, but it is better not to purchase glasses with a too-thin frame - the lower part of the face will strongly stand out. The most important thing is to expand the cheekbones, soft and rounded frames will come to the rescue.
The Importance of Wearing Sunglasses
The results of a recently completed study showed
that the risk of developing exfoliative eye syndrome, which leads to
glaucoma, retinal vein thrombosis, and cataracts,
is associated with the duration of a person’s outdoor presence.
The results of a recently completed study showed that the risk of developing exfoliative eye syndrome, which leads to glaucoma, retinal vein thrombosis, and cataracts, is associated with the duration of a person’s outdoor presence.
It is known that exfoliative syndrome is often observed among the indigenous people of Australia, spending a lot of time daily outdoors. However, until now, the existence of a connection between the occurrence of this syndrome and the intensity of ultraviolet insolation has not been precisely proven, since there were some other conflicting reports in the scientific literature on this subject.
The authors of a new study studied the relationship between the development of the exfoliative syndrome and the intensity of ultraviolet radiation. They performed a retrospective analysis of case histories of patients from US clinics (control group - 106 patients, the main 118 patients) and Israel (72 and 67 patients, respectively). Scientists analyzed the climatic characteristics of the places of residence of the study participants, as well as how many hours they spend weekly on the street.
As it turned out, the risk of developing exfoliative syndrome increased by 11% for every degree of latitude removal from the equator. Just one hour a week, spent in the summer on the street, for the whole life of the patient increases the risk of this pathology by 4%.
In the USA, where people wear sunglasses or contact lenses with ultraviolet filters almost every day in the summer, the risk of developing exfoliative syndrome was significantly lower than in Israel.
Also, during the study, it was found that working on snow or near open water bodies also has a negative effect on the organ of vision. In addition, scientists came to the conclusion that wearing hats with wide brim does not protect the eyes from the negative effects of ultraviolet radiation.
Based on the data, ophthalmologists recommend that all people, when they stay in the fresh air, especially in the summer, systematically use sunglasses or modern contact lenses that have UV filters that can absorb more than 99% of the ultraviolet rays of the sun that are harmful to the eyes.
