Did you know that about 64% of the world population wears eyeglasses? According to Vision Council research, about 75% of adults (above 40 age) and 35% of people below 30 have prescribed low eye correction eyewear. We know a majority of people use eyeglasses to correct their farsightedness or nearsightedness. If you remember, in the past few decades, contact lenses were used as cosmetics. But, in today’s world, technology and medical science has evolved.
Today, contact lenses are so advanced that they are widely used as vision-correcting eyewear. However, there are some things that you might need to know about contact lenses. That’s why in this article, we’ve written an ultimate guide on eye contact lenses and how you can protect your eyes while wearing contact lenses. So let’s get into it!
What are Contact Lenses?
Contact Lenses are medical wear that is worn directly on the tear film of your cornea. A tear film refers to that oily layer above the cornea on which you place the lenses. Like eyeglasses, contact lenses are also widely used to correct the refractive errors in your eye. A refractive error happens when your pupil can’t focus the light beam on the retina. It either focuses the light beam front or behind the retina, which causes blur in vision and visual error in your eye.
Contact lenses are designed to change the light passing through your iris. As a result, this modified light beam can focus ideally on the retina and correct visual impairment in your eyes. Contact lenses are usually a piece of plastic that is bent according to eye structure. Their thickness is modified according to the visual error of your eye, so the modified light beams can focus on the retina.
Eyeglasses vs. Contact Lenses
If you don’t have perfect eye vision or 20/20 vision, then your doctor might suggest wearing eyewear to correct your vision errors such as eyeglasses. However, you can choose between eyeglasses and contact lenses. Today, contact lenses are widely used to correct the wrong vision problems such as farsightedness and nearsightedness. However, eyeglasses and contact lenses have their pros and cons; below, we’ve made a comparison of eyeglasses vs. contact lenses:
There are two types of eyeglasses, single vision glasses, and multifocal glasses. Single vision glasses are used to correct nearsightedness when you can’t see distant objects. At the same time, multifocus is used to correct farsightedness when you can’t see close things. In the past, glasses used to be made up of glass. However, drinks made of glass can be hazardous because if it is broken, it can cause serious injury to the eye. That’s why today, modern glasses are made up of high-quality plastic that is difficult to break until you hammer it potentially and doesn’t cause any severe damage if it gets a break while wearing.
Contact lenses are different from eyeglasses. However, both have the same concept but work differently. Contact lenses are thin discs of plastic that sit directly on your cornea’s oil. They are used for two different purposes, and some people use contact lenses as a cosmetic to change the color of the iris to look beautiful. In these types of lenses, a thin plastic disc is used. The manufacturer But most people use contact lenses for their eyesight correction and correct the visual errors of their eyes.
Why Wear Contact Lenses?
You can use contact lenses for several reasons, such as using them to change the color of the iris in the name of fashion. However, the majority of people use it for eyesight problems. If your lifestyle isn’t suited to wearing glasses regularly or you want a change in your lifestyle, contact lenses might be a good option. If you’re also thinking the same, then you’re not alone. More than 165 million people around the globe wear contact lenses.

In that case, contact lenses might help you to get rid of these problems.
Are Contact Lenses Safe to Wear?
Many people still think that disposable contact lenses might not be a good thing for the eyes. Doctors confirmed this theory in the past, but today, medical science has solved many things that were a problem in the past. The same thing applies to contact lenses. Modern contact lenses technology is 100% safe, even for long-term uses. All you’ve to do is to wear them on your cornea, and you’re ready to go!
Material from which Contact Lenses are made
In the past, contact lenses used to be made up of glass that was extremely dangerous. Because even a tiny crack in a glass-made lens can seriously damage your eye or can cause complete blindness if they break while you’ve worn them. Moreover, glass contact lenses were cumbersome that made them uncomfortable for anyone who used them. However, after the invention of PVC, today’s contact lenses are made with plastic. They are 100% safe because they consist of extreme flexibility that makes plastic lenses almost unbreakable while in use. Also, they are 8x lighter than glass lenses. That’s why today, contact lenses are 100% safe and comfortable for your eyes!
Types of Contact Lenses
Contact lenses come in various types. Usually, there are three types of contact lenses used. However, all contact lenses require a valid prescription provided by the doctor. Below we’ve mentioned the most common three types of contact lenses:
Soft Contact Lenses
Soft contact lenses are usually made up of soft and flexible plastic that allows air passage to your cornea. They are incredibly comfortable and perfect for prolonged usage. Soft contact lenses also contain a silicon pad that makes the lens very soft, flexible, and comfortable to your eyes. However, one drawback of these lenses is that You can’t use them if the vision error is high or multiple layers are required since their structure is designed to apply two or more layers to them.
Rigid Gas Permeable Contact Lenses
RGP contact lenses are more robust, durable, and last longer than soft contact lenses. They are more resistant to deposit buildup and give a more clear vision. RGP lenses are usually more affordable than soft lenses since their technology is old and are easy to build. Moreover, their life is about 4x higher than soft contact lenses, and they can support two or more layers at a time. Hence, for a person whose eyesight is extremely weak or has mixed eyesight, RGP lenses are perfect. But, unfortunately, they are not that lightweight and comfortable compared to soft lenses and might feel uncomfortable for the first few uses.
Extended Wear Contact Lenses
Extended wear contact lenses are a mixture of RGP and soft contact lenses. They are made up of silicone gel + plastic disks that make them affordable, comfortable, long-lasting, and breathable. They tend to be used by people who need to wear their contact lenses for a long time. Although they are a bit heavier than soft contact lenses but comfortable enough that anyone can wear them comfortably for the whole day without itching or rashes. The silicone material allows the air to pass through from your cornea, and plastic disk keeps the cost lower that’s why it’s the most common type of lens used by the majority of the public.
How to Protect Your Eyes While Wearing Contact Lenses?
Note that contact lenses might be a better choice, or they can be a worse choice. It depends on how you use them and how properly you care for your eyes while wearing contact lenses. For your ease, below, we’ve mentioned some tips on how you can protect your eyes while wearing contact lenses:
Always Keep Your Lenses Clean
Make sure that you keep your lenses always clean. Always ensure to wash your hands properly while wearing or removing your lenses from the eye. A small bacteria can cause a lot of damage in the future and is the most significant cause of infection in the eye.
Never Ever Clean Lenses with Water
Water contains Hydrogen that is not good for your lenses and may reduce the expiry of your lenses. Moreover, water contains other bacteria; you can’t say that the water you’re using is 100% free from bacteria. The bacteria in the water can damage your lenses that may also cause an infection in your eyes.
Never Sleep with Lenses
Of course, at night, you don’t use your eyes and see objects. So why do you need to wear lenses even at night? According to researchers, your lenses don’t have any source of air passage while you’re sleeping that can cause an infection in your eyes and damage the cornea. Of course, your eyelid is closed while sleeping, so how can you expect air passage while sleeping?
Only use Lenses if Prescribed by the doctor.
It’s not always the case that your eyes are made for lenses. If your doctor has prescribed you eyeglasses, then only wear eyeglasses. We don’t recommend trying lenses without a prescription from a doctor because your doctor will first examine if your eyes can afford contact lenses or not.
