8 Ways Your Eyes Change With Age

Our eyes and vision change with age. Your eye doctor can monitor these changes — some of which are a natural part of the aging process — and identify any eye conditions or diseases early enough to treat them and prevent vision loss. Read on to learn more about the different types of eye changes one may encounter with age.

Age-Related Eye Conditions and Diseases

Cataracts

If your vision is starting to get blurry, you may be developing cataracts. There are a few types of cataracts, but the one usually caused by aging is known as a “nuclear cataract”. At first, it may lead to increased nearsightedness or even a temporary improvement in your reading vision. But with time, the lens gradually turns more densely yellow and clouds your vision. As the cataract slowly progresses, the lens may even turn brown. Advanced yellowing or browning of the lens can lead to difficulty distinguishing between shades of color, and left untreated, it can eventually lead to blindness. Luckily, cataract surgery, where the cloudy lens is replaced with a clear lens, is an extremely safe and effective treatment option. 

Blepharoptosis

Blepharoptosis or ptosis is a drooping of the upper eyelid that may affect one or both eyes. The eyelid may droop only slightly or may droop enough to cover the pupil and block vision. It occurs when there is a weakness of the eye’s levator muscle that lifts the eyelid. This condition is usually caused by aging, eye surgery, or disease affecting the muscle or its nerve. Fortunately, blepharoptosis can be corrected with surgery.

Vitreous detachment

This occurs when the gel-like vitreous fluid inside the eye begins to liquefy and pull away from the retina, causing “spots and floaters” and, sometimes, flashes of light. This occurrence is usually harmless, but floaters and flashes of light can also signal the beginning of a detached retina — a serious problem that can cause blindness, and requires immediate treatment. If you experience sudden or worsening flashes and increased floaters, see Dr. Christopher Chiodo, OD immediately to determine the cause.

Other Age-Related Changes

In addition to the above eye conditions and diseases, the structure of our eyes and vision change as we get older. 

Presbyopia

Why do people in their 40s and 50s have more difficulty focusing on near objects like books and phone screens? The lens inside the eye begins to lose its ability to change shape and bring near objects into focus, a process is called presbyopia. Over time, presbyopia, also known as age-related farsightedness, will become more pronounced and you will eventually need reading glasses to see clearly. You may need multiple prescriptions – one prescription to enable you to see up close, one for intermediate distance, and one for distance vision. In that case, people often get bifocals, multifocals or PALs, and they can be combined with contact lenses as well.

Reduced pupil size

As we age, our reaction to light and the muscles that control our pupil size lose some strength. This causes the pupil to become smaller and less responsive to changes in ambient lighting. The result? It becomes harder to clearly see objects, such as a menu, in a low-light setting like a restaurant.  

Dry eye

Our tear glands produce fewer tears and the tears they produce have less moisturizing oils. Your eye doctor can determine whether your dry eye is age-related or due to another condition, and will recommend the right over-the-counter or prescription eye drops, or other effective and lasting treatments, to alleviate the dryness and restore comfort.

Loss of peripheral vision

Aging causes a 1-3 degree loss of peripheral vision per decade of life. In fact, one may reach a peripheral visual field loss of 20-30 degrees by the time they reach their 70s and 80s. While peripheral vision loss is a normal part of aging, it can also indicate the presence of a serious eye disease, like glaucoma. The best way to ascertain the cause is by getting an eye exam. 

Decreased color vision

The cells in the retina responsible for normal color vision tend to decline as we age, causing colors to become less bright and the contrast between different colors to be less noticeable. Though a normal part of aging, faded colors can at times signal a more serious ocular problem. 

Beyond the normal changes that come with age, the risk of developing a serious eye disease, such as age related macular degeneration and glaucoma, increases. Routine eye exams are essential to keeping your eyes healthy. Your eye doctor can determine whether your symptoms are caused by an eye problem or are a normal byproduct of aging.

Why You Regularly Need to Replace Your Sunglasses

Did you know that sunglasses, or at least sunglass lenses, regularly need to be replaced? 

According to a study conducted at the University of São Paulo, the UV protection that sunglasses provide deteriorates over time. You may adore your current ones, but if you’ve been rocking those shades for two or more years, it might be time to get a new pair. 

In addition to the UV-blocking properties, anti-reflective and anti-scratch coatings wear down, and the frame material may become brittle over the years, too. Even if you have the most durable sunglasses available, regular lens-replacement is the best way to ensure that your vision is maximally protected from the harmful effects of ultraviolet light. 

UV Light and Sunglasses

The protective efficacy of your sunglasses comes in large part from the lens coating of dyes and pigments that reflect and absorb ultraviolet radiation. They create a barrier that prevents UV radiation from penetrating your eyes.

However, this protective coating can, and often does, break down over time. Wear and tear can cause an invisible web of tiny abrasions, compromising its UV-blocking power. Furthermore, the protective dyes and pigments aren’t able to absorb UV rays indefinitely; the more sunlight they’re exposed to, the more rapidly they’ll become ineffective. 

A pair of shades worn on occasion and in mild conditions is likely to remain effective longer than a pair that is heavily used in a more intensely sunny environment. For example, if you spend long days on the water paddling, kayaking, or canoeing, the protective coating on your lenses will deteriorate more quickly than it would if you only wear your shades to go grocery shopping or sit in a cafe. 

Why It’s Important to Protect Your Eyes From UV

Protecting your eyes from the sun is critical no matter where in the world you are, as UV exposure places you at risk for developing eye diseases like eye cancer, pterygium, and pinguecula — which can result in disfigurement and discomfort — as well as cataracts and macular degeneration — which cause vision loss and, in severe cases, blindness.

Even short-term overexposure can result in photokeratitis, a corneal sunburn. Symptoms include eye pain, swelling, light sensitivity, and temporary vision loss. Some people experience it when spending too much time boating or skiing without wearing eye protection. Snow and water can increase solar exposure because they reflect sunlight toward your face.  

What to Look for When Getting New Sunglasses

When choosing new sunglasses, make sure they’re labeled 100% UV protection or UV400. Although most pairs sold in the United States and Canada offer this degree of protection, it’s still worth confirming before making the purchase. Keep in mind that factors like cost, polarization, lens color, or darkness don’t have much to do with the level of UV protection. Even clear prescription lenses can be UV protective. 

It’s important to note that there is a lot of counterfeit sunwear in the marketplace. This is dangerous since counterfeit eyewear may not provide much-needed ultraviolet protection. So if the price of a renowned brand is too good to be true, it’s probably a fake. 

The size and fit of the sunglasses is important. Bigger is definitely better if you spend a lot of time outdoors. Larger wrap-around eyewear is best if you regularly ski or spend many hours in the water, as this style blocks light from all directions. 

To find out whether it’s still safe to wear your favorite shades, visit a Las Vegas eye doctor to determine whether your lenses still offer the right level of UV protection. It’s also a good opportunity to discuss prescription sunwear.

Cataract Awareness Month

June is Cataract Awareness Month. During this important time, people living with cataracts (and their loved ones) are encouraged to talk about their personal experiences by giving each other helpful information and sharing their knowledge and advice. Use the hashtag #CataractAwarenessMonth on your social media channels to encourage and support others.

Did you know that over 24 million Americans have cataracts? More than 3.5 million Canadians are blind from cataracts, making it one of the most common – and serious – eye conditions today. Dr. Christopher Chiodo, OD treats cataract patients from all over Las Vegas, Nevada with the newest and most effective methods of eye care.

With millions of people living with the condition, it’s now more important than ever to bring awareness to this serious condition.

What Are Cataracts?

So what exactly are cataracts?

The lens of the eye is normally clear, which allows you to see things clearly and in sharp detail. Over time, the lens can become cloudy, causing blurry vision. It’s as if you’re looking through a dirty window and can’t really see what’s outside. This clouding of the lens is called a cataract, and it can affect one or both of your eyes.

What Causes Cataracts?

Aging is the most common cause of cataracts. The lens of your eye contains water and proteins. As you age, these proteins can clump together, and when that happens, the normally clear lens becomes cloudy.

Did you know that certain types of major eye surgeries and infections can trigger cataracts? Other issues that can lead to cataracts include congenital birth defects, eye injury, diseases, and even various kinds of medications. If you’re already developing cataracts, be careful when going outside. UV rays from the sun can make cataracts develop faster.

How Can I Lower My Risk of Cataracts?

Certain risk factors increase your chance of developing cataracts. These typically include:

  • Diabetes
  • Excessive alcohol consumption
  • Family and medical history
  • Medications
  • Obesity
  • Smoking
  • UV ray exposure

To lower your risk, consider reducing your alcohol intake, quit smoking, start an exercise program, eat foods rich in vitamin A and C, and wear 100% UV blocking sunglasses.

Common Symptoms of Cataracts

If you have cataracts, you may experience some common symptoms like:

  • Blurry vision
  • Colors that used to be bright now appear dim
  • Double vision
  • Glare from natural sunlight or from artificial light, like light bulbs and lamps
  • Halos around lights
  • Night vision problems
  • Sensitivity to light

If you or a family member notice any of these signs, talk to Dr. Christopher Chiodo, OD right away. The sooner you seek treatment, the faster we can help you get back to clear vision.

Coping With Cataracts

If you’re experiencing vision problems from cataracts, there is hope. If you have a mild case, a combination of a different eyeglass prescription and better lighting in your home, office, or other environment can improve your vision. In more advanced cases, your optometrist will likely recommend cataract surgery to remove the cloudy lens and replace it with a clear one.

Do I Need Cataract Surgery?

Cataract surgery is one of the most common procedures today. In fact, the American Academy of Ophthalmology estimates that 2 million people undergo the procedure each year.

During the procedure, the doctor will gently remove the cataract from the eye and replace it with an artificial intraocular lens (known as an IOL). Because it’s a common procedure, cataract surgery is usually performed in an outpatient clinic or in your eye doctor’s office. There is no need to stay in a hospital and you can usually resume your normal activities in just a few days.

If you’ve exhausted every other solution and still suffer from blurry vision from cataracts, surgery may be an option. Schedule a consultation online or call 702-254-6222 to book an eye doctor’s appointment at The Vision Centers and together, we’ll determine if cataract surgery is right for you.

During this Cataract Awareness Month, share your stories and successes, and give your loved ones hope for a healthy and high quality of life.
