The cornea of your eye is a transparent, spherical dome that covers the iris and pupil. A healthy cornea is smooth and bends evenly in all directions, allowing light to concentrate correctly on the retina at the rear of the eye. This is what makes it possible for you to see clearly. When your cornea isn’t uniformly shaped, light refracts wrongly, resulting in hazy vision. Corneal astigmatism is a misshapen cornea. The lens of your eye, which sits right beneath your cornea, can also develop astigmatism. When you’re told you have lenticular astigmatism that indicates your lens is misshaped
Objects close and far may look fuzzy, regardless of whether you have corneal or lenticular astigmatism. Whether mild or severe, astigmatism can cause eye strain, squinting, persistent headaches, and impaired night vision. It can also happen due to an eye injury, illness, or surgery. Because astigmatism is frequently inherited, most persons who have it were born with it.
Treatment of Astigmatism
Astigmatism can be treated in a variety of ways. Many individuals wear eyeglasses with a unique cylindrical lens prescription that compensates for their astigmatism. Most individuals who use glasses to correct astigmatism require a single-vision lens that allows them to see clearly at all distances. Bifocal or progressive vision lenses are more likely to be required by those over 40. Contact lenses are a good alternative for many people with a modest bit of astigmatism. Some persons with astigmatism may benefit from contact lenses rather than spectacles since contacts may give clearer vision and a wider range of vision than glasses.
Individuals, however, have claimed to have blurry visions with contacts. Here’s why you may be experiencing blurry astigmatism contact.
- Old prescriptions
An outdated prescription is the most prevalent cause of hazy vision, even while wearing contact lenses. Your refractive defects will progress; therefore, you must stay on top of them. Even if you only need a new prescription every five years, staying on top of this change ensures that you can see well for longer.
- New prescription
Your eyes will need to adjust if you recently changed your prescription. You may have developed a habit of squinting, blinking, or moving your head to improve your vision. These modest habits may add a little eye strain with a new prescription. Your eyes should acclimatise to the new prescription in two weeks or less, and you should be able to see well without any problems.
Astigmatism is a condition in which your eyesight is hazy at all distances. This is caused by an oddly shaped cornea, which makes contact lens fitting more difficult. Your contact lens may slide out of position more frequently, causing your vision to blur. You may help yourself by blinking the contact lens back into position or using eye drops. Still, it would be best if you also chatted to your optometrist or ophthalmologist about astigmatism-specific contact lenses.
- Incorrect fit
There are a few more reasons your contact lenses could not suit your eyes, so you should test a few different kinds to determine which ones work best for you. Due to under-correction, brands that do not rest correctly on your eyes might cause eye strain or distort your vision.
- Wearing for too long
Your contact lenses will accumulate dirt and proteins from your eyes throughout the day. Take them out and clean them with the proper contact lens solution when they get uncomfortable. Please leave them in the solution for many hours, preferably overnight, to remove all the debris and put them back on in the morning. Contact lenses have varied shelf life depending on the kind. Some contact lenses, for instance, are designed to be used for only one day, while others may be worn for up to a month. Make sure you know how long you can safely use your contact lenses and how to dispose of them once they’ve reached the end of their shelf life. Wearing them for prolonged periods raises the risk of infection and reduces the lenses’ effectiveness.
- Dry eyes
If you experience dry eyes regularly for whatever reason, you should consult your eye doctor about the best way to wear contact lenses. Your contact lenses won’t have a surface to float on if your eyes are too dry, and they won’t be able to interact effectively with the natural lens within your eye to refract light. Depending on the severity of your dry eyes, you may need to use eye drops many times each day or investigate alternative solutions besides contact lenses.
- Eye Floaters
Floaters or transient spots that float in and out of your range of view are possible. Your contact lenses may appear to be changing in your eyes. For a short while, this may impair your vision. Eye floaters, on the other hand, can be found in the vitreous gel that makes up the majority of the centre of your eye, and they get worse as you get older. Floaters are less noticeable when your eyes are healthy, including keeping your contact lenses clean and your prescription current. You may have an underlying problem that requires treatment if it suddenly worsens.
One symptom of cataracts is blurred vision. However, you won’t notice this symptom until your cataracts have advanced rather far. Regular eye exams will allow your eye doctor to detect tiny spots or patches of cloudiness in your lens, even if you haven’t experienced any changes in your vision. The evolution of this problem, which might take decades to become serious, will be monitored by your eye specialist. One technique to control cataract symptoms is to use glasses to correct your eyesight. In the early phases of cataract development, you may be able to wear contact lenses; nevertheless, at some point, contact lenses may be less effective than high-prescription glasses.
- Eye infections
Blurry vision and discomfort of the eyes are two symptoms of an eye infection. Blurry vision, whether with or without contact lenses or glasses, might indicate the presence of viral diseases such as herpes. Having to wear contact lenses increases your risk of trapping pathogens or dirt in your eye; wearing contact lenses for too long increases your risk of scratching or puncturing your eye, allowing bacteria or fungus to pass through; and wearing contact lenses for too long increases your risk of scratching or puncturing your eye, allowing bacteria or fungus to pass through. Stop using your contact lenses if your eyes feel irritated or red, itchy or swollen, or if you develop discharge, and see your optometrist for treatment. If left untreated, infections can cause long-term damage to your eye, so get care right away.
