What Are Snowstorm Cataracts? How Can You Treat

Snowstorm cataracts are a type of cataract that is caused by exposure to cold weather. Symptoms include blurred vision, sensitivity to light, and difficulty seeing in low-light conditions. If you are experiencing any of these symptoms, it is important to see your eye doctor as soon as possible. In this blog post, we will discuss the causes and treatment options for snowstorm cataracts.

What Is a Snowstorm Cataract?

What Is a Snowstorm Cataract?A snowstorm cataract is a type of lens opacity in the eye caused by an accumulation of tiny white particles or granules on the surface of the lens. These deposits cause vision to become cloudy and unfocused, similar to looking through a foggy window. It is a type that is similar to nuclear cataracts, except that snowstorm cataracts are caused by granular deposits rather than a single large deposit.

It is estimated that snowstorm cataracts account for about 10% of all cases of lens opacification. They are commonly seen in older individuals, though they can occur at any age. Therefore, if you are experiencing cloudy vision it is important to get a comprehensive eye examination.

What Are Some Signs To Look For?

There are several signs that may indicate a person has developed snowstorm cataracts. Some of these are as follows:

  • Cloudy vision: It is one of the earliest and most common signs of a snowstorm cataract. The affected eye may appear cloudy or have a bluish hue.
  • Photophobia: Snowstorm cataracts can cause eyes to be more sensitive to light, leading to a condition called photophobia which causes discomfort in bright environments and makes it difficult for the person to see clearly during these times.
  • Halos: Halos are a common symptom of snowstorm cataracts, wherein the person sees a halo or ring around lights when they look at them. This is caused by light scattering as it passes through the lens of the eye and can be quite disorienting.
  • Glare: Glare from bright lights may also be a sign of snowstorm cataracts. This can make it difficult to drive at night or when the sun is shining brightly.

These are very common and easily recognizable symptoms of snowstorm cataracts and should be noted if they appear in combination. If left untreated, these can lead to more serious vision problems such as vision loss or even blindness.

What Are The Possible Causes Of Snowstorm Cataracts?

The exact cause of snowstorm cataracts is unknown, but there are several possible explanations for their development.

One possible explanation is that snowstorm cataracts are a result of long-term exposure to ultraviolet (UV) light, as UV radiation is known to damage the eye’s lenses. Additionally, certain medications and conditions such as diabetes can also increase the risk of developing snowstorm cataracts.

The causes of snowstorm cataracts may vary from person to person, so it’s important for people to discuss their individual risk factors with an eye doctor. Some common risk factors of snowstorm cataracts might include:

  • Age: Most snowstorm cataracts develop after age 40.
  • Gender: Women are more likely to develop snowstorm cataracts than men.
  • Certain medical conditions, such as diabetes and glaucoma.
  • Certain medications, such as corticosteroids or antidepressants.

It is important to understand that snowstorm cataracts may develop regardless of lifestyle and risk factors. So, be aware of the signs and symptoms of snowstorm cataracts and get regular eye exams.

How Is It Diagnosed?

The diagnosis is an important step in treating a snowstorm cataract. Your eye doctor will likely perform an eye exam, which may include a slit-lamp examination and other tests. During the eye exam, your doctor will look for signs of a snowstorm cataract, such as clouding of the lens or disruption in its surface.

Once the diagnosis is confirmed, your doctor may order imaging tests, such as an ultrasound or MRI, to get a closer look at the lens. This can help determine the extent of damage and plan treatment accordingly.

The right diagnosis can also help your doctor determine the most appropriate surgical option to treat a snowstorm cataract. Therefore, do not hesitate to ask as many questions as it takes for you to understand your condition and treatment options before proceeding.

How Can You Treat Snowstorm Cataracts?

How Can You Treat Snowstorm Cataracts?Treatments are important to help protect the vision of those who suffer from snowstorm cataracts. Depending on the severity of the condition, possible treatments include:

  • Wearing eyeglasses with an anti-reflective coating and high index lenses to reduce glare outside
  • Using artificial tears throughout the day to keep your eyes lubricated and help relieve symptoms
  • Taking a multivitamin to help support overall eye health
  • Using sunglasses with UV protection to reduce exposure to light and prevent further damage
  • Wearing contact lenses that filter out harmful blue light
  • Undergoing laser vision correction or cataract surgery to improve vision in cases where the cataracts are advanced

It is important to speak with your eye care provider to discuss the best treatment options for you. They will be able to recommend the appropriate steps and provide further guidance on how to manage snowstorm cataracts.

There is also a growing awareness of the importance of dietary change in preventing and treating eye conditions such as snowstorm cataracts. Eating a balanced diet rich in nutrients such as lutein and zeaxanthin, found in fruits and vegetables, can help protect your eyes from the effects of these cataracts.

It is also important to practice good hygiene habits, such as regularly cleaning contact lenses and eyeglasses and avoiding activities that may increase your risk of eye strain.

By following these steps and working with your eye doctor, you can help protect the vision of those affected by these cataracts and prevent further damage to your eyes. With proper management, it is possible to maintain a clear vision for many years to come.

Can It Be Prevented?

Well, the answer can sometimes be yes and sometimes no. There are some preventive steps that can reduce your chances of developing snowstorm cataracts. These include:

  • Wearing protective eyewear like sunglasses and hats
  • Avoiding excessive UV exposure
  • Staying away from cigarette smoke
  • Eating a healthy diet that is rich in antioxidants and omega-3 fatty acids
  • Getting regular eye exams to check for signs of cataracts

Overall, these things can help support the health of your eyes and reduce your chances of developing snowstorm cataracts. In terms of treatment, if you already have these cataracts then it will usually require surgery to remove the cloudy lens from your eye and replace it with an artificial one.

So, you can see there are always ways to manage cataracts. And hence, you should keep a lookout for the signs of snowstorm cataracts and take the necessary steps to prevent and treat them. Good luck!


To conclude, snowstorm cataracts may seem like an intimidating condition, but with the right medical attention and lifestyle choices, you can manage your symptoms and improve your vision. The key is to get checked early by an ophthalmologist because these cataracts often progress quickly and don’t resolve on their own.

With proper treatment and consistent follow-up care, it’s possible to not only slow the progression of your symptoms but also improve your vision. Treatment options include medications, laser surgery, and intraocular lens implants. Talk with your doctor to determine the best plan for you.
