Vision is one of the most important senses we have. It helps us to interact with the world around us and to perform daily tasks. 

However, as we age, our vision naturally begins to decline. But, there are times when our vision can become impaired more quickly than normal. If you’re having trouble with your vision and it seems to be getting worse, there could be a few different causes. 

In this blog, we’ll talk about the possible causes why your vision might be deteriorating.

1. Age-Related Macular Degeneration (AMD)

Age-related macular degeneration (AMD) is one of the most common causes of vision loss in people over the age of 50. AMD is a deterioration of the macula, which is part of the eye responsible for detailed central vision. AMD can cause blurred vision and difficulty seeing in low-light conditions.

2. Glaucoma

Glaucoma is a condition in which the pressure inside the eye slowly increases, damaging the nerve fibres that carry images from the eye to the brain. Symptoms of glaucoma include blurred or hazy vision, difficulty seeing in low light, and difficulty recognizing objects in peripheral vision.

3. Cataracts

Cataracts are caused by a buildup of protein in the lens of the eye, which can cause cloudy or blurry vision. Cataracts can also cause difficulty seeing in low light and increased sensitivity to glare. 

4. Diabetes

Diabetes is a condition in which the body does not properly process sugar. If diabetes is not managed properly, it can cause damage to the blood vessels in the retina, leading to blurred vision and difficulty seeing in low light. 

5. Refractive Errors

Refractive errors are a common cause of vision loss. Refractive errors occur when the eye cannot properly focus light on the retina, leading to blurred vision and difficulty seeing in low light. Common refractive errors include nearsightedness, farsightedness, and astigmatism. 

6. New Glasses or Contacts

If you’ve been using the same prescription for a few years, it’s possible that your vision has changed, and you need an updated prescription. It’s important to visit an eye care provider regularly to ensure that your prescription is up to date.

7. Lifestyle

If you spend a lot of time looking at screens or if you’re not getting enough sleep, your vision can suffer. It’s important to take breaks from screens, get enough sleep, and wear sunglasses when you’re outside to help protect your eyes.

8. Side Effects from Medication

Some medications can cause dry eyes, which can lead to blurred vision. If a person is taking multiple medications, they should be sure to discuss any potential side effects with their doctor.

9. Undiagnosed Eye Infection or Inflammation

Eye infections, such as conjunctivitis, can cause blurred vision and other vision-related symptoms. If a person suspects they have an eye infection, they should see an eye doctor as soon as possible.


If you are experiencing any of the symptoms outlined in this article, it is important to see an eye doctor as soon as possible. Your eye doctor can assess your vision and determine the underlying cause of your vision loss. Early detection and treatment can help slow the progression of vision loss and may even improve your vision. 

Depending on the cause of your vision changes, your eye care professional can prescribe medication, glasses, or contact lenses to help improve your vision. In some cases, surgery may be necessary to correct vision problems. 

If you are concerned about your vision, don’t wait to seek help. Making an appointment with an eye doctor is the first step toward preserving your sight.
