If I ask you a question that Why do we wear sunglasses? Your answer would be, of course, to protect our eyes from the extreme sunlight. Usually, we wear sunglasses on hot summer days when the harmful radiations from the sun are at an extreme. So would sunglasses be effective against them if they are of bad quality?
Therefore, it is important to pay attention to what you purchase and from where you do so. Getting a good quality pair of sunglasses should be your priority. Some stores sell cheaper glasses because their lenses are not capable of blocking harmful ultraviolet solar radiation.
Therefore, while buying something for your eyes, you should never opt for a cheaper option. Even if you can’t spend too much, you can buy some at discount from quivedo.com. They have all the brands including Ray-Ban, Oakley, Tom Ford, Gucci, and Persol.
And the amazing thing is that you get at least a 10 to 40 percent discount on all these brands at quivedo.com. So what’s stopping you from getting the latest designs? You can protect your eyes and look stylish at the same time, without spending much.
Choosing the sunglasses
The quality of the lens is quite important while choosing sunglasses. Because these are the ones that are going to prevent any harmful effects of sunlight. So here are the things that you should pay attention to, as they will help you to get good quality glasses.
1 – Look for ultraviolet label
If the lenses are offering protection against UV rays, the brand will give that detail on the label. The label will either say that you get 100 percent UV protection or the UV 400 filter category. Both of these lines say the same thing that the lenses are capable of blocking all the harmful radiations from the sunlight.
UV 400 means that the lenses will block all the solar radiations of up to 400 nanometers wavelength. So you can move around during broad daylight without worrying about your eyes. So while shopping, do look for this label.
But beware of the thing that some sellers fake the labels. You can detect it from the shop and the price that they have to offer. For example, you can buy Gucci sunglasses for 100 euros, however, the seller is offering them for 50 euros. Thus, irrespective of the tag, you can know that what you are getting might not be the original Gucci.
2 – Use a UV flashlight for test
You can easily get a UV flashlight, it will help you with the purchase of the right sunglasses. So if you are not sure whether the lenses are completely effective against UV rays, you can do a test. Paper money has watermarks that become visible under UV light.
So you have to flash the light on any currency note and see the watermark from your glasses. If the watermark disappears, the lenses are surely offering 100 percent protection.
However, apart from the ultraviolet rays, there will be visible light too. So do not mix the two. You will be able to see things on currency notes but not everything. There are hidden watermarks or pictures that become visible only under a specific wavelength. Beware of this thing while doing your test.
3 – Always opt for a bigger size
Sunglasses are meant to protect your eyes. Therefore, bigger lenses mean that you will have more coverage from sunlight. Thus, your eyes will get less exposure and less damage. Usually, the sunglasses have bigger lenses. However, sometimes the trend brings smaller lenses to the front. And such trends are short-lived.
So do not worry about them. You are buying the product for protection. And anything that is offering protection should not be a trend. So prefer oversized or wraparound style glasses while shopping. These will help reduce the solar reach from the sides too.
4 – The darker the lenses are the better they perform? No
Dark and light are merely shades, they help your eyes to get comfort. That is why they do not have a significant impact on radiation protection. Darker lenses reduce the extreme light penetration and thus, we can see around comfortably. This does not have anything to do with the blockage of ultraviolet light.
5 – Polarized lenses are not UV protecting
Polarized glasses are quite effective against reflective surfaces. They reduce the glare that comes from pavements or water bodies. That is why they are highly used while driving. However, the polarized lenses do not necessarily mean that they are protecting you against ultraviolet light.
So if you have to drive a lot, you can get a pair of those. Moreover, you can also use them while enjoying the seaside. It will make your time more comfortable and pleasant. So note the difference between the two and don’t get confused.
6 – Note the expiration date
Lenses do have an expiration date. They become ineffective after a certain period because of their high solar exposure. Usually, the expiration date is two to three years. The protective layer becomes damage over time when you expose it to the Ultra Violet rays. So when you buy an expensive set of sunglasses, make better use of them. Otherwise, they won’t be much effective after a few years.
7 – Material of the frame
High-quality sunglasses have frames made from good material. So while shopping, pay attention to the material and note that whether it feels smooth or not. There are plenty of materials like acetate, metal and wood. Some offer sweat resistance while others are much more durable.
8 – Nose pads
Make sure that the nose pads of your glasses are smooth and comfortable. Some sunglasses have tough pads, which makes you feel uncomfortable. Moreover, they also put some pressure on your nerves. Instead, you should look for the flexibility of the nose pads. Make sure you do not feel hurt while wearing the glasses.
