Every day technology is advancing, leading to new products in the market with respect to the current technology. Contact lens is among the products which are affected by how technology changes. Hence it is the reason you’ll find different types of contact lenses in the market.
If you are thinking about ditching your glasses or changing the contact lens, first of all, you need to familiarize yourself with the types available in the market, and once that meets your needs.
All the types of contact lens you’ll find in the market are meant to help adjust vision and lifestyle. It can be hard to select which one is right for you, but that is where we come in. In this blog post, we have categorized all the types of contact lenses according to a type of correction, material, comfort, color variation, among other factors.
Kinds of contact lens are there in the market.
Categorization according to the materials and comfort
In this first category, there are two types of contact lenses. They differ according to the material used to manufacture them and their comfort.
Soft contact lenses
Soft contact lens is one of the common types of lens you can find in the market today. These contact lenses are made up of soft plastics, and they drape gently over the cornea. If you go for the latest soft contact lens, they are made up of silicone hydrogel. It is a material that is used to allow adequate oxygen to your cornea. Before buying these latest lenses, it is imperative to talk to your doctor about the silicone hydrogel.
Hard contact lenses
Hard contact lenses, also known as Rigid Gas Permeable lenses, are less common contact lenses. These types of lens are meant to offer an excellent vision to those patients who have higher astigmatism.
RGP lenses can take a few days to adjust to, especially if you’re a first-time user. RGP lenses additionally necessitate a thorough fitting process due to the lens specifications’ exceptional precision. So accurate, each lens is custom-made to your exact specs! As a result, they are the sole item on our website that is a final sale.
Soft lenses are increasingly frequent since they provide instantaneous all-day wear and can be safely worn while participating in sports (RGP lenses cannot). Consult your eye care provider to determine the best material, curvature, and replacement plan for you.
Categorization according to Replacement schedule
Behold, considering the material, there is also a need to consider the replacement schedule. Hence taking the replacement schedule, the following are a type of contact lens in the market today.
Daily wear contacts
Daily wear contacts can be worn the whole day up to the number of hours determined by your eye doctor, but they must be removed, disinfected, and cleaned every night.
Extended wear contacts
Under the supervision and consent of your eye doctor or fitter, extended wear contact can be used overnight. Some lenses can be worn for up to 30 nights in a row, depending on the brand. Consult your doctor to see if your eyes are healthy enough to wear contact lenses at night.
The two above contact lenses are all disposable contact lenses, even though some can be used for a longer period. Your eye doctor will work with you to develop a replacement schedule that is right for you. There are several alternatives to pick from depending on your requirements:
Daily disposable contact lenses
Daily contacts are the healthiest alternative for your eyes since they provide you with a new lens every day without needing to worry regarding protein deposits or cleaning schedules. One-day lenses are also an excellent option for those who wish to wear their contact lenses just on rare occasions.
Weekly contacts are typically taken out at night for cleaning and discarded once a week. These lenses offer a pleasant wearing experience as well as a cost-effective replacement schedule.
These contacts can last up to 30 days if properly cared for. Pick a day of the month as a reminder when it’s time to change your lens. For all types of prescriptions, these lenses are available from a variety of companies. If your eye doctor says it is okay, you might be able to wear it overnight.
Categorization according to Prescription options
The third category is according to the prescription options, and there are different types of contact lens to serve any vision problem. Under this category, the following are contact lenses you can find in the market.
Spherical contact lenses are the most popular contact lenses, and they are used to correct myopia and hyperopia. Additionally, if your glasses prescription has a “CYL” value of 0.75 or less, you won’t notice a CYL in your contact lens numbers and can wear a spherical lens.
Toric lenses correct astigmatism by changing power as it travels around the lens – this occurs when your lens or cornea is almond-shaped rather than spherical. As you move your finger across the lens, the correction power changes.
The CYL and AXIS values on these lenses will most likely differ from those on your glasses prescription; your eye doctor or fitter will change those values based on how the lens rests naturally on your eye.
Around the age of 40, everyone requires additional magnification to read and see nearby items well. Presbyopia develops as the natural lens in our eyes stiffens with age, making it more difficult to concentrate close up. With multifocal lenses, you can get rid of those reading glasses dangling from your neck or stored in your breast pocket.
Colored contact lenses are a great way to add some zing to your eyes! These can be worn for aesthetic purposes or to correct vision. Colored contacts should be prescribed by your eye doctor regardless of the correction (or lack thereof) in the lens, as they are a medical device that sits on your eye’s fragile structure.
If your vision correction necessitates it, any contact lens will be available as toric or multifocal regardless of a replacement schedule.
Categorization according to Colour variation in contact lenses
Pale eyes have long been desired due to their rarity and recessive genetic origin. There was no way for persons born with dark eyes to imitate the appearance of blue or green eyes until the invention of colored contacts.
Colored contacts are becoming increasingly popular among actors and actresses, whether or not they are required to correct refractory mistakes. Colored contact lenses, like any other type of contact lens, must be fitted and recommended by a doctor.
Opaque contacts lens
A solid coating of color around the iris and a clear center are painted on opaque contacts. They’re made to lighten even the darkest of eyes. Because the natural appearance of the eye is obscured, opaque lenses can conceal the underlying hue.
Enhancers, also called medium tints, are designed to enhance or change the color of one’s eyes without masking them. Enhancers are intended for those with pale eyes and have no impact on people with dark eyes.
Visibility tinted lenses
A very tiny colored tint, usually blue, is added to visibility tinted glasses. They will not affect or disguise the eye color in any way, unlike opaque lenses and enhancers. Instead, the colors are meant to assist a lens to stand out in a lens case or if it falls out or is dropped. VISITINT or LiteTint are other names for visibility lenses.
Monovision contacts are recommended for patients with presbyopia, with one eye adjusted to see far away and the other set to see close up. Because minds are smart, the eyes and brain eventually adjust to produce one clean field of view.
You must be able to read your prescription to purchase contact lenses online. The numbers for your contact lens prescription are based on your glasses prescription; however, they can vary, especially for higher prescriptions. This is one of the reasons why it’s crucial to seek the advice of an eye doctor.
To ensure that your contacts fit your eyes properly, you must choose them carefully. Your eyes, like people, come in a variety of forms and sizes, and they change form over time. Above all, it’s critical to wear contact lenses that protect your eyes.
Contacts must provide the best possible oxygen and moisture flow. All of the oxygen in your cornea (the clear dome on the front of your eye) comes from the air around it. Therefore your lenses must not only enable oxygen to travel through the material and move just enough to keep a microscopic layer of tears flowing beneath the lens, which helps carry oxygen and clean the lens.
By allowing more oxygen into the eye, you can view the world as it should be seen. Even contemporary materials, however, can harm your cornea if the fit isn’t perfect. Ascertain that your eye care specialist has examined the lens’s movement on your eye and determined that it is safe to wear.
