Facts About Cataracts: The Leading Cause of Blindness for Those 55 and Older

Cataracts are the leading cause of blindness for those 55 and older worldwide, according to the World Health Organization’s analysis of the most recent census. More than half of Americans over the age of 75 have some degree of cataract formation in their eyes. With so many people experiencing the effects of this eye condition, it is even more important that you are well informed about what cataracts do and what you can do to prevent them.

Cataracts may seem like a scary, difficult-to-understand eye problem, but never fear. Here are eight facts to help you start understanding cataracts and their combatants.

Facts About Cataracts

1. The History of Cataracts

The name comes from the Greek word kataraktēs, meaning “waterfall.” The Greeks and Romans thought cataracts were formed by evil liquids that flowed like a waterfall into the eye. This can be explained by the cloudy appearance of cataracts – it looks like a foreign liquid may have seeped into your lens, if you look closely.

Ancient Egyptians had a particular interest in optometry as well. An Egyptian papyrus dating to 1,500 BCE describes what was probably a cataract under the phrase “the mounting of water in the eye.” Clearly, this ocular problem has been effecting humans since the beginning of history.

2. What Happens When You Get a Cataract

Facts About Cataracts ImageA cataract is a clouding of the eye’s lens, which is normally clear. A healthy lens allows light to pass through to the back of the eye, so that the patient can see well-defined images. A cataract scatters the light as it passes through the lens, preventing a sharply defined image from reaching the retina. As a result, your vision becomes blurred, like looking through a fogged-up window.

Some cataracts are congenital, but most are caused by aging. Because cataracts impede your vision, they often prevent patients from being able to do things like read and drive as easily.

3. How to Know If You Have a Cataract

Cataracts develop over time, so some people do not even realize they have a problem, especially if they are already wearing glasses. These changes in your vision may be signs of cataract:

  • Blurred or double vision, ghost images, or a “film” over the eyes
  • Worsening night vision
  • Difficulty seeing while reading or performing other close-up work under standard lighting conditions
  • Sensitivity to light and glare
  • Frequent changes in vision prescriptions

If you are experiencing any of these symptoms, it is best to visit an eye doctor for an official diagnosis. Even if you do not think you have any vision problems, annual eye exams are still a good idea. This is especially true since cataracts and their symptoms can sneak up on you.

4. Uncontrollable Risk Factors for Developing Cataracts

Cataracts are the leading cause of blindness, making their prevention even more important. Unfortunately, there are several factors that we cannot control that may increase the risk of developing cataracts, including age, family history, and ethnicity.

African Americans and Hispanic individuals have a higher risk for developing and becoming blind from cataracts. Researchers do not know why these groups develop cataracts more frequently yet, but if you fall into one of these groups, it is important that you are extra vigilant about going to the eye doctor.

Some studies also suggest that women may be at a slightly higher risk than men. Research shows that this increased risk comes from higher levels of estrogen in women.

5. Controllable Risk Factors for Developing Cataracts

There are many things you can do to reduce your risk of developing cataracts. Smoking can increase your risk, so quitting that habit is an important first step. Too much sunlight can also cause cataracts, so reducing your exposure to sunlight by wearing UVA/UVB protective sunglasses and wide-brimmed hats is a good idea. According to a recent study conducted in India, cataracts are very prevalent in type-2 diabetic patients, so pursuing a healthy lifestyle to reduce your risk of developing diabetes will also reduce your risk of developing cataracts.

6. The Frequency of Cataract Surgery

Cataract extractions are the most common surgical procedure in the United States: almost four million are performed each year. On average, the out-of-pocket cost for cataract surgery is $3500 per eye. That adds up to a grand total of $14 billion spent on cataract surgery in the U.S. each year. Luckily, cataract surgery is usually a fairly painless procedure and is easy to recover from. However, it is better to avoid needing surgery altogether by practicing the following steps.

7. The Importance of Diet in Cataract Prevention

A recent study published in the journal Nutrients touted the benefits of a healthy diet for preventing cataract development. They found that increasing your carotenoid intake is one of the best ways to avoid getting cataracts later in life. Carotenoids are abundant in dark green and leafy vegetables like kale and broccoli. They are also found in orange and red fruits and vegetables, such as tomatoes, peaches, squash, and, of course, carrots.

8. Adding Supplements Can Help Fight Cataracts

Most of us do not eat enough fruits and vegetables to get the nutrients we need to fight cataracts. A great way to add more of these essential vitamins is to add eye vitamin supplements to your health and wellness regimen.

Rebuild Your Vision’s Ocu-Plus Formula has 17 vitamins and nutrients that will not only help prevent cataracts, but will strengthen your vision overall. In particular, research suggests that supplementation with N-acetyl and L-cysteine may play a role in preventing cataracts or slowing their progression. Additionally, nutrients like lutein and zeaxthanin may combat cataract development as well.

Knowing the Facts to Defeat Cataracts

With cataracts becoming such a prevalent problem in the United States as our population ages, it is more important than ever that you stay informed about what cataracts do and how you can prevent them. However, knowing the facts can slow the progression of cataracts and maybe prevent needing cataract surgery at all. Taking small steps like improving your diet and adding vision supplements can go a long way in preserving your vision for life – and saving you some money in the meantime.

    I had PRK 4 weeks ago tomorrow and soitmmees my vision still fluctuates a little but overall, I am 100% satisfied and have been for a couple of weeks already.At my last postop check (12 days postop), I was 20/30 in my right eye (also injured the cornea a little with a scratch 4 days before this appointment) and 20/20 in my left. I know my right eye vision has improved even more about as close to 20/20 as I can tell without an eye exam.My surgeon told me that my vision could fluctuate for 3-6 months and I’ve been able to correlate the blurred vision to dry eyes drops and blinking have helped to decrease that blur. But I’ve also noticed as time goes on, the fluctuating is decreasing.I’d say that my vision really started getting back to normal around 2-3 weeks. Be patient..you are nearly there :)I’m actually 100% satisfied and have been since 12 days postop going from worse than 20/400 to 20/30 in my right eye was awesome and being 20/20 in my left WOW!Just be patient you will probably really start seeing some differences within the next week. Just keep up with your drops (Pred Forte taper?? I was on Pred Forte on a taper for 3 weeks), and plenty of artificial tears as often as you need them that will help keep your corneas moist to aid in healing also take your Vitamin C 1000 mg a day (my surgeon told me to do this) and stay well hydrated with water.Good luck!

    Hello Tyler:
    We went to buy, and we found there are 3 types to choose from.

    1) N-Acetylcysteine
    2) L-cysteine
    3) N-Acetyl/L-cysteine

    Please advise which is best to take or if a combination is O.K..

    Thanks,
    As ever in The Spirit of Goodness,
