For some people, an astigmatism gets worse and is harder to correct than it was before. This type of astigmatism may be referred to as “worsened astigmatism.”
Your vision doctor can tell you more about how your astigmatism is affecting your quality of life.
How do you correct astigmatism with L?
Your L vision correction device is made up of a series of lenses (called multifocal lenses or MfLs), as well as some computerized software and sensors that make it possible to measure your eye’s refraction (how the light is bent when it enters an eye).
When you have astigmatism, your vision needs to be corrected with lenses that bend the light in different ways. Your MfLs will have different powers for different distances.
If you have an astigmatism, don’t be surprised if your vision doctor tells you that you need a different type of L device to correct your astigmatism. This is because it is a different type of refraction that is needed.
Your L device
A L device is different from most single vision (or monovision) glasses.
It is a multifocal (or bifocal) lens that can correct astigmatism and also correct nearsightedness (myopia).
These lenses correct astigmatism when worn at one distance, as well as correct nearsightedness at the same distance.
Some L devices are made up of a series of lenses (called “lenslets”), which are attached at the bottom of the device to create a continuous vision correction. Others are made up of a single lens. Each lenslet is the same power for the entire distance, with different powers for near vision.
Your L device may be refractive (or optical) or refractive and toric (or accommodative).
A L device is made up of a series of lenses, as well as computerized software that measures and records your eye’s refraction.
The lenses are made of glass, plastic, or silicone (a hydrogel).
You can buy a “prescription” pair of L devices. These lenses need to be prescribed by your eye doctor. They can be made to order, or you can order a pair that you’ve already had your eye exam for, and they can be shipped to you.
Some people may prefer to buy refractive L devices. These devices are made out of glass or plastic and have a series of lenses. They are designed for correction of all distances in one lens.
You can buy a refractive L device to correct astigmatism only, or to correct astigmatism and nearsightedness.
You can also buy refractive and toric L devices. These have a single lens with different powers for distance and near vision.
Most L devices are a refractive and toric L device.
You can also buy L devices that are accommodative or presbyometric.
They may be refractive and accommodative L devices or presbyometric L devices.
These are sometimes called “multi-focal” or “multi-accommodative” L devices.
Refractive and toric L devices
Refractive and toric L devices are multifocal lenses that correct astigmatism at one distance and also correct nearsightedness at the same distance.
You can get a prescription for these lenses, either as a pair or as one lens. You can also buy refractive and toric L devices that are already prescribed.
You can buy a refractive L or toric L device that is made up of a series of lenses, with the same prescription for the entire distance.
These lenses are sometimes called “multi-focal” or “multi-accommodative” L devices.
Presbyometric L devices
Presbyometric L devices are multifocal lenses that correct astigmatism at one distance, as well as correct nearsightedness.
You can get a prescription for this type of device, either as a pair or as one lens. You can also buy refractive and toric L devices that are already prescribed, or you can order presbyometric L devices that are made from scratch.
You can also buy presbyometric L devices that are made up of a series of lenses. These lenses are designed to correct astigmatism and nearsightedness in one lens.
Astigmatism may come and go
Astigmatism is a way of describing how the light enters your eye. It is an imperfection in the eye that causes problems with your vision.
Most people with astigmatism have a single type of astigmatism that can be corrected by a L device.
Some people have astigmatism that comes and goes. It may be worse in one eye, and then improve in another.
This is called “worsened astigmatism.”
Some people are born with astigmatism that is fixed. Even if they don’t have astigmatism, they may still have it after they’re born.
Other people have astigmatism that lasts and then improves.
Astigmatism and your eye
Your eye is made up of a series of lenses that bend light. It’s how your eye corrects for nearsightedness (myopia).
It’s also how your eye corrects for astigmatism.
Astigmatism is not the same thing as “hyperopia,” which is when your eye is too short or too long.
Hyperopia is not the same thing as astigmatism.
Astigmatism may be in one or both eyes. It is common to have astigmatism in both eyes.
It may also be that you have astigmatism in one eye, and another eye may have astigmatism that is different from the astigmatism in your dominant eye.
Astigmatism is most often found in one eye, but it can also exist in both eyes.
How does astigmatism affect your vision?
Astigmatism can affect the way you see objects that are far away. You may see things blurry.
Astigmatism is usually worse at close range. It usually improves when you move back and forth from a far distance to a close distance.
The way you see things may be different than people who have no astigmatism.
- Astigmatism is a type of eye disorder. It is often related to an eye injury or a birth defect.
- Most people with astigmatism have a single type of astigmatism that can be corrected by a L device.
- Astigmatism may be in one or both eyes. It can also be present in both eyes.
- Astigmatism can be worse in one eye, and then improve in another.
- Astigmatism is not the same thing as hyperopia, which is when your eye is too short or too long.
If you have a L device for astigmatism, it’s important that you get your prescription refilled every year. You can get a prescription refilled at your eye doctor’s office. Some eye doctors can refill your prescription online.
