What Is Toric and How Does It Affect Your Contact Lens Choice?

Quick Answer

A toric contact lens is a specialized lens designed to correct astigmatism, a condition where the cornea is shaped more like a football than a basketball. Unlike standard spherical lenses, toric lenses have different powers in different meridians and must stay oriented correctly on your eye. If you have astigmatism, toric lenses are often the right choice for clear, comfortable vision.

If you've been told you have astigmatism, you've probably heard the word 'toric' thrown around. But what does it actually mean, and how does it affect which contact lenses you can wear? This guide breaks down the basics of toric lenses, how they work, and what to consider when choosing contacts.

Whether you're new to contacts or considering a switch, understanding the difference between toric and spherical lenses is key. We'll also touch on whether colored toric contacts exist and what your options are if you want both vision correction and a new look.

What Is Astigmatism and How Do Toric Lenses Work?

Astigmatism is a common refractive error caused by an irregularly shaped cornea or lens. Instead of being perfectly round, the cornea is curved more in one direction, causing light to focus on multiple points in the eye rather than a single point on the retina. This results in blurred or distorted vision at all distances.

Toric lenses correct this by having two different optical powers — one for the steep meridian and one for the flat meridian. They also have a specific axis orientation that must align with your eye's astigmatism. To stay in place, toric lenses are weighted at the bottom or use a special design to prevent rotation. This is why 'how toric lenses work' is all about maintaining proper alignment.

• Toric lenses are available for both nearsightedness and farsightedness with astigmatism.
• Your eye care professional will measure your prescription, including the axis, to fit toric lenses correctly.

Toric vs Spherical Contact Lenses: What's the Difference?

Spherical contact lenses have the same power across the entire lens, like a ball. They correct nearsightedness or farsightedness but do not address astigmatism. If you have astigmatism and wear spherical lenses, your vision may still be blurry, especially at night or when reading.

Toric lenses, on the other hand, are customized with different powers and an axis. They are slightly thicker on one side to keep them oriented correctly. This makes them a bit more complex to fit and often more expensive, but they provide the clear vision that astigmatism requires.

• If you have mild astigmatism, your eye doctor might suggest trying spherical lenses first, but toric lenses are the proven solution.
• Toric lenses come in daily, monthly, and even colored options, so you can find a style that fits your needs.

Do Colored Toric Contact Lenses Exist?

Yes, colored toric lenses are available, but they are less common than standard toric lenses. They combine the corrective power of a toric lens with a tint or pattern to enhance or change your eye color. If you have astigmatism and want colored contacts, you'll need to find a brand that offers toric versions.

At LENSTOWNUS, we carry a range of colored contacts, but not all are toric. For example, the Silimedi Palm Brown and Davivi2 Brown are non-toric colored lenses designed for those without astigmatism. If you have astigmatism, you'll need to look for specifically labeled toric colored lenses or consult your eye care professional for options.

• Always check the product specifications for 'toric' if you have astigmatism.
• Colored toric lenses may have fewer design choices, but they do exist.

Product Facts: Non-Toric Colored Contacts

• Silimedi Palm Brown: Type: 3 Months, Pieces: 2pcs / bottle, Total Dia: 14.7mm, Graphic Dia: 14.0mm, Base Curve: 8.7mm, Water Content: 43%, Material: Silicone Hydrogel This lens is not toric, so it's for people without astigmatism. Its larger graphic diameter can make eyes appear bigger, but if you need astigmatism correction, this won't provide it.
