Astigmatism glasses: a guide to understanding the need for and types of

putting eyeglasses on a man with astigmatism

Astigmatism affects the shape of your cornea and how you perceive light. When astigmatism goes untreated, it can cause headaches, eye strain and other discomfort — even for mild cases.

Astigmatism can be treated several ways — from contact lenses to eyeglasses and even surgery. Of these solutions, glasses for astigmatism are among the most popular, and serve wearers of all ages well. 

But how do you choose the right pair of astigmatism glasses? This guide will help you understand how glasses help astigmatism, as well as lens types and some top brands to consider. 

What lenses are used for astigmatism? 

Both lens power and lens technology play a big role in correcting astigmatism.

Astigmatism affects the shape of the cornea; rather than being shaped “normally” like a baseball, astigmatism causes the cornea to more closely resemble the shape of an American football or an egg. Because of this, light is processed differently through the eye. This is where a specific astigmatism lens power for eyeglasses comes in handy.

Cylinder (CYL) is the part of eyeglass prescription that indicates additional power is needed to correct astigmatism. If you have astigmatism that needs correction, this will be shown on your prescription, because it is a critical element of your corrective lenses.

Lens power isn’t the only important part of astigmatism glasses, however.

Features to consider for astigmatism lenses

Astigmatism can cause headaches, eye strain and even trouble with night vision. Because of this, there are key lens features to consider when astigmatism patients choose a pair of glasses.

Blue light blocking lenses

Eye strain is one of the most common symptoms of astigmatism. If you regularly use a computer or other digital screens that emit harmful blue light, you can aggravate this tension. In fact, excessive screen time can even cause digital eye strain, particularly for those with uncorrected astigmatism. 

Fortunately, blue light blocking lenses can alleviate this discomfort, and make working on your laptop or texting on your phone much more enjoyable.

Anti-reflective (AR) coating 

This type of coating allows your eyes to focus properly on the visible light entering your eyes, which allows for optimal vision. 

AR coating is also helpful for driving at night, since it eliminates reflections and glare from oncoming headlights, as well as streetlights. This is particularly helpful for those with astigmatism who may have trouble seeing at night.

Ultraviolet (UV) protection

Bright sunlight can contribute to headaches, a burden that many with astigmatism already face. Those with more severe astigmatism may also have heightened light sensitivity. For these reasons, UV protection is a feature to consider for astigmatism glasses. 

Progressive lenses for astigmatism

When vision needs correction for near- and farsightedness as well as astigmatism, progressive lenses are an optimal choice. Progressive lenses are especially beneficial for those experiencing age-related farsightedness (presbyopia) who also have astigmatism.

Lens brands for astigmatism glasses

Based on your personal lifestyle, some brands of astigmatism glasses may be more suited for you than others. The following lens brands are among the highest rated for astigmatism correction:

Eyezen lenses

These single-vision lenses are designed to protect against pixelated and digital screens, making them a great choice for those with astigmatism — especially for anyone who spends a lot of time using computers and/or other digital devices.

Varilux X Series lenses

These lenses can help your vision automatically adjust to different image zones and eliminate distortion that is often a byproduct of astigmatism.

Varilux E Series lenses

If you need progressive lenses, lenses from the Varilux E Series could be a great fit for you. These lenses allow for a seamless transition from reading far away objects like road signs and street names to nearby objects, like books and menus.

Transitions XTRActive lenses

Headaches are common among those with astigmatism. Since bright lights can cause headaches (especially for those with light sensitivity), Transitions XTRActive, which protect eyes from harsh lights and glare is another brand to consider.

Should you wear glasses all the time for astigmatism?

When astigmatism is left untreated (whether the condition is minor, moderate or severe), it can cause discomfort in the form of headaches, eye strain and more. This can unquestionably present a distraction from everyday activities and work.

It’s important to follow your eye doctor’s recommendations for treating your astigmatism and wear your prescription eyeglasses on a regular basis (especially while driving). Alternating between glasses and no glasses can stress out your vision and cause astigmatism symptoms to worsen.

Adjusting to new glasses for astigmatism

Getting used to a new prescription or a change in lenses usually takes a few days — but for some, it could take up to a week or two for eyes to fully adjust. 

It’s normal for headaches to occur during this transitional period, but if you experience several days of distorted vision or heightened symptoms of astigmatism or discomfort, contact your eye doctor as soon as possible.
