At the optician, optometrist or eye doctor you may have heard about these three notions. But what do they mean? Do you always need one of them?

What are "Spheric"", "Toric"" and "Multifocal" contact lenses?

Are you tired of wearing glasses but still want to see clearly? Contact lenses might be the solution for you! However, with so many options available, it can be overwhelming to choose the right one. Let's break down the three main types of contact lenses: spheric, toric, and multifocal.

Spheric contact lenses are the most common type and are used to correct nearsightedness or farsightedness. They have a uniform curvature across the entire lens, which helps to correct vision in all directions. Think of them as the ""basic"" contact lens option.

On the other hand, toric contact lenses are designed for people with astigmatism, which is when the cornea is shaped more like a football than a basketball. These lenses have different curvatures in different areas of the lens to help correct the irregular shape of the cornea. So, if you're tired of seeing the world in a blurry, football-shaped haze, toric lenses might be the way to go.

Lastly, multifocal contact lenses are designed for people with presbyopia, which is when the eye's natural lens loses flexibility and makes it difficult to focus on close objects. These lenses have different prescriptions in different areas of the lens, allowing for clear vision at all distances. They're like the Swiss Army knife of contact lenses - versatile and able to handle any situation.

So, whether you're a spheric, toric, or multifocal kind of person, there's a contact lens out there for you. Don't be afraid to talk to your eye doctor and try out different options until you find the perfect fit. After all, seeing clearly is worth the effort!

What other types of contact lenses are there?

Contact lenses have come a long way since their inception in the 1940s. Today, there are a variety of contact lenses available to suit different needs and preferences. Here are some of the other types of contact lenses that you may not have heard of:

Soft contact lenses: These are the most popular type of contact lenses and are made of a soft, flexible plastic material that allows oxygen to pass through to the cornea. They are comfortable to wear and come in a range of options, including daily disposable, bi-weekly, and monthly lenses.

Rigid gas permeable (RGP) lenses: These lenses are made of a rigid, oxygen-permeable material that allows for better vision correction than soft lenses. They are also more durable and can last longer than soft lenses. However, they can take some time to get used to and may not be as comfortable as soft lenses.

Toric lenses: These lenses are designed to correct astigmatism, a condition where the cornea is irregularly shaped, causing blurry vision. They are available in both soft and RGP materials.

Multifocal lenses: These lenses are designed to correct presbyopia, a condition where the eyes lose their ability to focus on close objects as we age. They are available in both soft and RGP materials.

Colored lenses: These lenses are available in a range of colors and can be used to enhance or change the natural color of your eyes. They are available in both prescription and non-prescription options.

Which type of contact lens do I need?

Once you've decided on the material, you'll need to consider the wearing schedule. Daily disposable lenses are convenient and require no cleaning, while monthly lenses are more cost-effective but require daily cleaning and storage.

It's also important to consider your lifestyle and hobbies. If you play sports or have an active lifestyle, daily disposable lenses or RGP lenses may be a better option. If you work long hours on the computer, you may benefit from lenses with blue light blocking technology.

Ultimately, the best type of contact lens for you depends on your individual needs and preferences. Consult with your eye doctor to determine the best option for your eyes and lifestyle.
