6 Reasons to Use a Screen Protector for a Smartphone or Tablet Today (and Which Are Best)

Key Points

  • Screen protectors are essential for protecting smartphones and tablets from impact and scratches, as well as preventing the spread of bacteria.
  • They can absorb and disperse energy from falls, protecting the main screen of the device.
  • Screen protectors also offer antimicrobial protection, eliminating 99% of bacteria, fungi, and viruses that may be on the device’s surface.
  • They can filter out blue light emitted from screens, reducing eye strain and potential damage to the eyes.
  • Privacy screen protectors limit the viewing angles of the screen, preventing visual hacking and protecting sensitive information.

Smartphones and tablets have become many people’s most beloved companions. In addition to photos and music, they carry our social media apps, banking accounts, health data, and home security software.

Being unable to access our smartphone or tablet for a day or two because of a broken screen can really disrupt our lives. However, it is not uncommon for a shattered screen to render a mobile device unusable for weeks and even months.

We’ve seen many spend big bucks on a smartphone and a protective case, and within a few months, the screen is broken. Why not guard your mobile device with a screen protector and ward off any potential problems that come with accidental falls, blue light emission, and bacterial accumulation? 

If you want to navigate the evolving digital landscape with confidence, you have to be willing to add an extra layer of protection to your smartphone or tablet. Buy the necessary accessories, such as a screen protector, to help protect and keep the devices in a pristine condition.

Let us explain the biggest reasons why you should buy a screen protector today!

Impact Protection

Nearly everyone, however careful, has experienced those clumsy moments when the phone slips from your hand onto hard floors. Before smartphones, the worst encounters were the phone’s battery coming off and the casing cracking. Despite it sounding (and looking) bad, you could simply pick up the pieces, put them together with some bandaging and continue using your phone.

However, with smartphones and tablets, the story is different. A deep fear grips you as you silently pray (or loudly curse), hoping the screen is safe. Depending on the intensity of the fall and the surface, you can have either a cracked or a shattered screen. This is the main reason why people buy screen protectors.

The screen protector absorbs and disperses energy from impact. It will protect your device’s main screen so long as the drop shock is not more than what it can handle. It is important to note that protectors have advanced layers of polymers that can withstand hard knocks and drops. Besides, they are cheaper to replace than the mobile device’s main screen.

Scratch Protection

Despite warnings against putting phones in the pocket with keys or other objects, we still do, unconsciously. Consequently, the screen gathers scratches, causing it to become weaker and more susceptible to breaking on the slightest impact.

Besides weakening the screen, the scratches also destroy the phone’s aesthetics, making it look older than it really is. If you desire to resell it, such scratches will significantly lower its resale value.

However, a screen protector will shield your device’s main screen from these scratches. The beauty is that you can replace it whenever it starts to give your device a hazy and ugly look.

Antimicrobial Protection

There is a chance that your phone or tablet screen could be harboring a variety of harmful bacteria. Mobile devices carry ten times more dangerous pathogens than most toilet seats. You can better safeguard yourself against any disease-causing bacteria that may be growing on your touch device by installing an antimicrobial screen protector. 

Many screen protectors come with a special coating that can eradicate 99% of bacteria, fungi, and viruses that tend to crawl on your device’s surface. Antimicrobial screen protectors aren’t just designed for health workers. The truth is, we can all benefit from this type of screen guard. 

Eye Protection

Have you ever wondered why you get migraines whenever you spend too much time looking at a screen? It is due to exposure to blue light emitted from your electronic device. Overusing your smartphone or tablet can cause screen headaches and migraines.

Also, note that using your mobile device in a place with high light intensity, such as outdoors, can damage your eyes over time. So, if you find yourself squinting your eyes because of the reflection from the screen, install an anti-reflective (AR) screen protector. It is a simple solution to digital eye strain syndrome.

How Does It Work?

As light hits your device’s screen, the AR material bends certain wavelengths, reducing the UV rays reaching your eyes. As a result, it filters out blue light from your phone or tablet, increasing screen readability and allowing you to use your device under direct sunlight comfortably.

You can also use anti-glare screen guards for additional eye protection. Though usually used interchangeably with AR screen protectors, they are different. AR screen guards are designed to filter out UV lights from both the phone and the environment, while anti-glare protectors only reduce the reflection of light from the environment.

Despite the differences, both help protect your eyes from harmful, high-energy visible light emitted from your display. Studies have shown that too much exposure to blue light increases the rate of macular degeneration, cataracts, and eye cancers.

Visual Hacking Protection

Ever caught someone peeping over your shoulders while you text? Or have you been guilty of doing this?

While some people are simply curious and only want to check out what the user is watching or doing on the phone, visual hackers are not harmless. They have mastered the art of stealing your information without detection and have become better at it, especially in public spaces.

That’s why you need privacy screen guards. They are a special type of protector that use micro louver technology to limit the viewing angles of your phone. With these, the content on the screen is only clear to the person looking at it directly. Viewers from the side will see a blurred or dark screen. This makes privacy protectors very useful when accessing, viewing, or inputting sensitive information on your phone or tablet while in a public space.

There are two types of privacy screen guards with an extra layer to limit the angle from which one views the screen. You can choose a 2-way privacy screen guard or a 4-way privacy screen guard. The 2-way filter prevents viewing from left and right. 4-way privacy filters, on the other hand, prevent unwanted insights into your screen from all four sides: left, right, top, and bottom.

Prevention of Fingerprint Smudges

Scratches and cracks make a phone unusable, but nothing leaves an ugly look like oily fingerprints. When the phone’s screen is off, you can see all the swipes, dots, and prints, and however much you wipe and wash your hands, these marks will still remain on your device’s main screen. It is also impractical to wipe the screen each time you use it.

A screen protector offers the best solution against unpleasant marks. Most screen protectors come with an oleophobic coating that is oil resistant. This ensures fingerprints won’t ruin your device’s screen.

The anti-smudge coating does not make the screen less sensitive to touch. In fact, on the contrary, it offers smooth, frictionless scrolling. So, a screen protector with the best oleophobic coating will help prevent your smartphone’s or tablet’s screen from gathering fingerprints. It will also improve your touch experience.

Common Screen Protector Materials

Now that you know the benefits of having a screen protector, let’s take a look at the different types of screen protectors on the market.

For the most part, you can use only one type at a time. However, some can be used together without making the screen much thicker. It all depends on the level of protection you are looking to achieve.  

While you can get all the above benefits from any of the types discussed here, remember some are better in certain aspects than others.

  • Tempered glass
  • Polyethylene Terephthalate (PET)
  • Thermoplastic polyurethane (TPU)
  • Nano-liquid

Tempered Glass

Tempered glass screen protectors are the strongest and offer the highest level of protection against drop impact and scratches. They contain multiple layers, including anti-glare, anti-reflective, oleophobic nano-coating, and privacy filters.

You can also opt for one with a reflective surface, which you can use as a mirror when the screen is off. It can come in handy when you need to check yourself and there is no mirror at hand or you are in a setting where using a handheld mirror would draw unwarranted attention.

Though they offer better resistance to drops and scratches, tempered glass protectors have some downsides. They are expensive and thicker than high-grade plastic options. Also, on extreme impact, they shatter, leaving an ugly appearance that requires replacement. Nonetheless, they are a better option than replacing the device’s screen.

Polyethylene Terephthalate (PET)

PET is the plastic used in the making of water bottles. It is light and almost unnoticeable when added to a phone or tablet screen. It is also the cheapest option on the list. However, this does not mean PET screen protectors are unreliable, but the truth is they are not as strong as tempered glass and thermoplastic polyurethane.

They provide a smooth layer and are suitable for scratch protection, however, they offer no impact protection or any other benefit. As the saying goes, you get what you pay for.

Thermoplastic Polyurethane (TPU)

If you need a high-grade plastic screen protector with edge-to-edge protection, go for thermoplastic polyurethane. It is more rubbery than PET, making it better for abrasion resistance and impact protection.

It is also scratch-proof. However, it is not as smooth as the two above, can be notoriously tricky to apply, and adds an off-color hue to the phone’s screen.

Nano-Liquid Protectors

Vendors and manufacturers claim that these liquid coatings can protect against scratching and impact. In fact, some of them feature an antimicrobial coating, meaning they can protect you from disease-causing microbes.

Unlike the PET, TPU, and tempered glass protectors that require you to consider the phone’s measurements and screen design, nano-liquid protectors can fit on any screen. The only challenge is that you can only use the liquid on top of a different screen protector.

Remember that you cannot remove the nano-liquid once applied, so you have to wait until it wears off —unfortunately, there are no visible ways of knowing when the protector has worn off. Also, you can never tell between the protector and the screen.

Smartphones and tablets are expensive, and repairing their screens can cost up to a third of the price of a new phone. Screen protectors are cheaper and help keep your tablet and phone screen in one piece protecting you from costly screen repairs and replacements. However, it is worth noting that protectors will only safeguard the front part of your gadget. You will need a quality case to protect the back, corners, and edges.

The sensitivity will remain the same whether you buy a tempered glass or a plastic film screen protector. Essentially, screen guards are designed to provide necessary protection without compromising the touch sensitivity and clarity of the display.

Does my Gorilla Glass phone need a screen protector?

Gorilla Glass will provide scratch and impact protection. However, different versions offer different levels of reliability. So, if the version on your phone is designed to survive drops, you might need a protector with scratch resistance capabilities. It is worth noting that Gorilla Glass also does not offer privacy protection, anti-glare, and UV light filtering. Therefore, you might as well need a screen guard to complement what is missing on your main screen.

What causes bubbles under screen protectors?

Bubbles are a sign that the protector is not applied correctly. They are the first point of weakness and significantly reduce the lifespan of the protector. To avoid them, seek the help of an experienced person when applying a screen protector.

What is an oleophobic coating?

Most new smartphone manufacturers list oleophobic coating as one of their unique selling points, USPs. It is just the fancy name for anti-fingerprint coatings that repel skin oil.

Which is the best screen protector material?

It all depends on your needs, but if you do not mind the thickness, tempered glass is widely regarded as the best choice. It offers high-impact protection. Besides, you can bundle anti-glare, privacy protection, and antimicrobial coating onto one tempered glass screen protector.

Should I use a liquid protector?

You  can but only as an extra protection to either plastic or glass protectors.
