Why Sunglasses Are Important - How Sunglasses Protect Our Eyes

Sunglasses

Sunglasses are an essential fashion accessory, which is why they must not only offer an aesthetic contribution to the wearer, but also effective protection. The sunglasses can not be confined to one or the other, but are well link the aesthetics, the index protection, and even add practicality and strength which will make an important asset, daily, but also over time.

To choose your pair of sunglasses, you must take everything into account: UV protection, quality of materials, and wearing comfort, as well as the shape of the frame. This is why we are going to explain to you how the protections work and discuss the different glasses!

Sunglasses: how does it work?

Trendy accessory or sun protection, with the arrival of sunny days, sunglasses are making a comeback. Do you know how to choose them and which glasses are suitable for your eyes? We are shedding light on the subject. Our eyes are complex organs, which function as a super camera. The function of the eye is to capture and process the light emitted by the objects around us. Schematically, the rays of light pass through the cornea and the pupil to the lens. The latter focuses so that the image is clear and the optic nerve transmits the image to the brain for interpretation. Our eyes are also fragile organs that need to be protected from the sun like our skin, and we don't always know how to do it.

Did you know, for example, that dark glasses protect against glare, but not necessarily against UV? Did you know that children's fancy sunglasses rarely protect their eyes well? It is, however, an important condition for sunglasses! Why should your children wear sunglasses if they do not protect them from UV rays? Choosing pretty frames for sunglasses that do not protect, is like buying a sunscreen whose packaging would please us aesthetically, or that we would find softer than another, but still undergo the rays of the sun...

UV filters to protect our eyes from the sun

Sunglasses are not just a fashion accessory. They are especially very useful to protect our eyes from the sun and that is why we must understand how they work. Indeed the sun emits heat, light, but also ultraviolet rays UVA and UVB which can be harmful to our eyes. Sun filters, therefore, protect our eyes from direct sunlight, but also from reflected rays. White surfaces, sand, water, and snow emit reverberations that must be protected. Snow, for example, reflects 80% of the sun's rays and at altitude, the number of UV increases by 10% every 1,000 meters. This is also why skiers or hikers often have their eyes armed with sunglasses with powerful protection.

A European standard classifies sunglasses into 5 categories, it is with this standard that you must choose your sunglasses:

• Category 0: no solar filtration
• Category 1: low solar brightness
• Category 2: average solar brightness
• Category 3: strong solar brightness
• Category 4: exceptional solar brightness

The lenses of your pair of sunglasses should, therefore, take into account its future use and not just the perceived fragility of your eyes. If you want to take a pair of the sun that will follow you everywhere, by default always take a category 3 minimum. You will always be sure to be well protected.

CE standard for sunglasses

The European CE standard is mandatory to be able to market sunglasses in all countries of the European Union. This CE logo marking is affixed by the manufacturers on the glasses and represents a guarantee of quality, since it implies construction and performance requirements. It must be legible, visible and indelible. CE marked sunglasses are required to comply with health, safety, and environmental protection standards. They must :

• - filter UV rays
• - mention the filtering power of the glasses
• - not be toxic or allergenic due to their composition
• - be accompanied by a detailed notice in the language of the country of sale

To choose your sunglasses optimally, choose a filtration category that suits your needs and make sure that the CE marking is present. Always prefer a purchase from an optician, who is the only professional able to advise you on effective eye protection... Branded Sunglasses in Pakistan

Sunglasses: amazing glasses

Trendy fashion accessory, sunglasses are making a comeback as soon as summer arrives. Which color and which treatment will you choose to be stylish while protecting your eyes well? To choose your sunglasses correctly, you must respect two main criteria when it comes to lenses:

• The protection index: it goes from category 0 which has almost no solar filtration to category 5 designed for extreme solar brightness.
• CE marking: the CE logo engraved on the glasses by the manufacturers represents a guarantee of quality. It certifies that your sunscreens filter UV rays and mentions the filtration category.

 The colors of sunglasses

You will also have to choose the color of the lenses of your sunglasses. Several options are available to you:

Classic colors: Brown increases contrasts and reduces glare. Gray decreases the brightness and intensifies the colors. Green amplifies contrasts and limits visual fatigue. If you suffer from a vision defect, we recommend brown glasses for short-sighted people, gray glasses for astigmatic and green glasses for hypermetropic and lens wearers. The ideal remains, of course, to try them to see what suits you best in terms of visual comfort and color reproduction.

Original colors: For aesthetic reasons, you may want to choose more original colors. The yellow or orange lenses improve the contrasts in low light. Pink or red lenses should only be worn in low light. Blue or purple lenses are recommended in case of moderate sunshine. Yellow, pink, blue, even two-tone, these original glasses are certainly very stylish but do not provide sufficient protection in strong sunshine...

Your sunglasses can also benefit from specific treatments:

Polarized lenses: Polarized lenses filter out reflected light rays. In particular, they remove the reflections generated by bodies of water. They, therefore, provide great visual comfort if you practice nautical activities.

Gradient lenses: Gradient lenses have several successive shades. For example, the top can be category 3 and the bottom can be category 2. This allows you to read a book in a very sunny space, without being dazzled when you take your eyes off your book.

Mirrored lenses: To get a mirror effect, the lenses are covered with a mirrored layer that prevents people in front of you from seeing your eyes. These glasses considerably reduce reflections.

Photochromic lenses: Photochromic lenses change color depending on the brightness. The more the sun shines, the darker their color. These lenses are very practical for people who wear corrective glasses. No need to change glasses when you go out in the sun.

Treat yourself by choosing your sunglasses! Aesthetics are important, but protecting your eyes from the harmful UV rays of the sun should remain your priority. To do this, call an eye care professional.

Sunglasses: choosing your protection

Do you want to buy sunglasses and wonder which lenses will provide the best protection for your eyes? We take stock of the issue.

When the days get sunny, you often want to buy sunglasses and succumb to the latest trends. However, you should not stop on the aesthetic side. Indeed, the sun protection index of glasses is a very important element to take into account to protect your eyes from the harmful ultraviolet rays of the sun.

To standardize practices throughout the European Union, a standard has been created with 5 protection categories:

Category 0 glasses: These glasses are lightly tinted, but almost do not filter UV (up to 20% maximum). They essentially meet an aesthetic need.

Category 1 glasses: These glasses are suitable for low sunlight. They filter between 20 and 57% of UV. You can use them in mid-season (spring and fall).

Category 2 glasses: These glasses protect from average sunlight. They filter from 58 to 82% of UV. They will serve you for cloudless sunny days.

Category 3 lenses: These lenses are perfect in strong sunlight, typically for the beach in summer or skiing in winter. They filter UV from 83 to 92%.

Category 4 glasses: These glasses are reserved for situations of extreme sunshine (high mountains, desert ...). They filter UV up to 97%. Be careful however, these glasses are prohibited for driving vehicles because they impair vision and colors.

 Protect your children's eyes

Your children's eyes are more fragile than yours. Until adolescence, the lens of their eyes does not fully play its role. It is clearer than that of an adult and lets UV rays reach the retina. You may be tempted to buy fancy tinted glasses by the beach for your kids, but it's a false good idea. These glasses do not contain a UV filter and will only protect them from glare. And as they decrease the light intensity, their pupils will expand and allow more UV to pass. These glasses, therefore, produce the opposite of the desired effect. If you think that the lifespan of a pair of children's glasses is too short to take quality glasses, think again, especially since there are very good pairs of children's glasses at affordable prices...

Buy your sunglasses from an online optician

For adults as for children, sunglasses are best purchased from an eye care professional, namely an optician on the internet. It will help you to determine the right category of lenses according to your use as well as the frame adapted to your morphology. His glasses will be CE certified, a guarantee of quality and safety. Finally, he can adjust your glasses to your face and provide you with after-sales service if necessary. If you don't buy your sunglasses from an optician, you risk buying a counterfeit product. Remember that the purchase of a counterfeit product can cost you several hundred euros in fines and that the latter may present irreversible risks to your health.

Sunglasses: a face, a shape? 

When you buy sunglasses, in addition to protection and the type of glasses, you often wonder which frame is best for your face shape. As with eyeglasses, it is always difficult to choose the ideal pair. We take stock and give you some tips so you can still get there!

The right shape for your sunglasses

To choose sunglasses that will fit you perfectly, you need to determine the dominant geometric shape of your face. It is not easy to define the shape of your own face on your own. You can test several methods:

• Put yourself in front of a mirror and draw on it the outline of your face with a lipstick.
• Take a selfie of yourself, print it and trace the outline of your face with a felt pen.

Once the shape of your face has been determined from among the 7 major types in existence, some advice is essential:

Round: Favor angular frames, which will slightly reduce the roundness of your face or narrow frames which will lengthen your face.

Oval: You can afford all styles of glasses. But try to respect your personality: the round glasses will tend to make you look young, the rectangles will look serious…

Triangle down: If your forehead is wider than your chin, choose rounded, rectangular or butterfly shapes.

Triangle up: If your chin is wider than your forehead, opt for oval or round glasses.

Square:  To soften your face and soften your straight lines, break the angles with round or oval frames.

Rectangle: A very visible frame of elongated or rectangular shape will give the illusion of cutting your face in half and thus reducing its length.

Rhombus: Opt for round, oval or butterfly frames... Branded Sunglasses in Pakistan

You will understand, in general, it is better to avoid choosing a shape of glasses that looks like the shape of your face. But the important thing is, of course, to feel good in your pair of sunglasses and that style suits you.

The right size for your sunglasses

You need to find sunglasses that highlight the shape of your face, but they also need to be the right size for you. For aesthetic reasons, but also for your comfort, several criteria are to be taken into account:

• The frame must be proportional to the size of your face,
• The frame should not compress your temples,
• The top of the frame should not hide your eyebrows,
• The sides of the frame should stop between the corner of your eyes and your ears,
• The bridge of the frame (the part that connects the two lenses) must be proportional to the distance between your eyes.

To choose your sunglasses well, you must know the shape of your face and prefer frames adapted to it. All you have to do is choose the color of your frame and your lenses. Your optician is there to advise you. Trust him, but above all treat yourself!
