What Happens to Our Eyes as We Age?

Baptist Eye Surgeons • December 14, 2020

Our bodies naturally change as we get older, including our eyesight. While some changes are common for everyone, others can pose a significant threat to the health of our eyes and vision.

It’s perfectly normal to experience changes to your vision over time. Focusing on close objects, differentiating between colors like black and blue, and seeing in dim light are all changes that can take place as you get older.

On the other hand, eye diseases like cataracts and glaucoma should not be considered normal and can lead to permanent vision loss. Take steps like getting regular comprehensive eye exams and making healthy lifestyle changes to help detect and prevent them. 

To help you prepare for changes to your vision as you age, we’ll look at:

  • Normal vision changes as we age
  • Causes of vision loss as we age
  • Preventing vision loss as you age

They say that change is inevitable. While this is true, preparing for and responding to changes in vision can lead to much better outcomes when things do change. Keep reading to learn what to expect from your vision as you get older and how you can protect your vision for the rest of your life.

Normal Vision Changes as We Age

Changes in vision are to be expected as we get older. Our bodies and physiology are constantly evolving. While these changes may come as a surprise for many people, many of them are common and allow patients and medical professionals alike to know what to expect. It’s important to know what is normal when it comes to changes in our vision, and what is not. 

As we age, it’s normal for people to experience:

  • Trouble focusing on objects that are up close
  • Difficulty telling the difference between colors such as blue and black
  • Problems seeing in dim light or adjusting to light changes

The lens in younger people’s eyes is naturally flexible, allowing them to see things up close more clearly. But as we get older, it can be more difficult to focus on objects that are up close , such as reading small print. This is due to the fact that our lenses become less flexible as we age, a condition known as presbyopia.  

Another problem older people normally experience is difficulty telling the difference between colors . When you’re younger, your lenses are clear and allow you to distinguish between differences in colors such as black and blue. Unfortunately, our lenses can begin to discolor as we age, making it difficult to distinguish between certain colors and shades.

You may also experience problems seeing in dim light, adjusting to light changes, and driving at night . One part of aging’s effect on our vision is needing more light to see clearly than you did when you were younger. Having more light around your home and work can help you see more clearly and improve your ability to see things up close more easily. 

Causes of Vision Loss as We Age

Issues such as trouble seeing up close objects, distinguishing between shades or colors, and poor vision in low light are to be expected as we get older. However, there are other age-related eye problems that are not part of the natural aging process. 

These eye problems include:

  • Cataracts
  • Glaucoma
  • Age-related macular degeneration
  • Diabetic retinopathy

These eye diseases can ultimately lead to vision loss and should be checked for and treated as soon as possible.

Cataracts

When the lens of the eye becomes cloudy, it’s known as a cataract . This clouding effect usually results in vision that has become more blurry or dim over time. It’s often described as a filminess or glare over the eye that becomes even more noticeable under bright light. Sometimes this clouding doesn’t result in vision loss. However, it’s still considered a cataract.

Glaucoma

Glaucoma is a disease that damages the optic nerve as we grow older. The optic nerve is extremely important for our vision since it’s what connects the eyeball and the brain. Glaucoma is usually caused by increased pressure in the eye. While this is the most common cause of glaucoma, it’s not always the case.

Age-Related Macular Degeneration

One of the most common threats to our vision as we get older is age-related macular degeneration, also known as AMD. This eye disease affects the retina, which is a layer of nerve cells that lines the back wall of your eye. AMD affects the retina and can lead to loss of central vision, especially for people over the age of 45.

Diabetic Retinopathy

Diabetic retinopathy is the leading cause of blindness in the US and cases are only increasing. When left untreated, high blood sugar can damage the blood vessels in the eye and result in loss of vision. Like AMD, diabetic retinopathy can do significant damage to the retina. Fortunately, early detection and treatment can help mitigate its effects.

Preventing Vision Loss as You Age

People tend to lose their vision to eye diseases gradually over time. This is why taking preventative measures early combined with comprehensive eye exams is so important. By getting regular comprehensive eye exams and pursuing a healthy lifestyle, you’ll be in the best position to catch problems early as well as prevent them from developing to begin with.

Comprehensive Eye Exams

Comprehensive eye exams are essential for catching vision loss as soon as possible. Regular exams give your ophthalmologist a chance to catch problems early as well as develop a treatment plan. It’s recommended that you start getting comprehensive eye exams once you turn 40 to help catch any issues before they become major problems for your vision. 

Get Plenty of Exercise

According to the American Academy of Ophthalmology, regular exercise is extremely important for eye health. Regular exercise promotes:

  • Blood circulation
  • Oxygen intake
  • Healthy weight

There are plenty of ways to get exercise without over-exerting yourself. It can be as simple as walking, stretching, or taking up a healthy hobby such as yoga or tai chi. 

Make Sure You’re Getting Enough Sleep

Sleep has tons of benefits for our bodies and minds. When it comes to our vision, sleep helps keep our eyes lubricated and prevents problems such as dry eye. Sleep also removes irritants such as dust, smoke, and allergens that may have built up in our eyes throughout the day. Sleep is incredibly important to your overall health, so make sure that you’re getting enough.

Protect Yourself From Harmful UV Rays

Too much sun can increase your risk of developing cataracts and AMD. That’s why you should invest in a quality pair of UV blocking sunglasses. UV rays are dangerous year-round, so make sure to wear your sunglasses whenever it seems necessary.

What to Expect During Your First Eye Exam: A Step-by-Step Guide

September 22, 2026
A thorough eye exam is an important part of keeping your vision healthy and protecting your eyes. If you are arranging for your first eye examination as an adult, if you are taking a child in for an evaluation, or if you have noticed any changes in your vision, knowing what to expect can help make the experience more comfortable. The eye exams carried out at Baptist Eye Surgeons not only check your vision but also look at your general eye health and spot any possible problems that might call for further investigation. What is the Importance of Eye Examinations? An eye examination does not merely enable one to find out if glasses or contact lenses are required. It lets an eye care professional assess how well your eyes are working and spot the signs of common eye conditions.  Some eye conditions can progress slowly without symptoms. Regular eye checkups can help detect changes earlier and make sure you receive appropriate treatment when needed. Step by step: The Process Involved in Having an Eye Examination Even though the different appointments may vary according to your particular needs, a typical full eye examination will involve a number of significant steps. 1. An Examination of Your Medical & Eye History Your appointment may start with questions about your vision, medical history, medications, any previous eye conditions, and your family history of eye disease. Be sure to report any changes in your vision, eye discomfort, headaches, or other concerns you have noticed. Your eye care professional may also ask about the glasses or contact lenses you currently use and how well they work for you. 2. Checking Your Vision A well-known part of an eye examination is the visual acuity test. You might be asked to read some letters or symbols from a chart at a set distance. This lets doctors assess how clearly you can see and decide whether corrective lenses would help. Further testing could assess your ability to see up close and the way well your eyes work together. 3. The Measurement of Eye Health & Function Your eye care professional might carry out a number of tests in order to assess the health and functioning of your eyes. The tests involved may vary depending on your age, symptoms, and risk factors and could include measuring eye pressure, examining eye movement and coordination, and looking at the structures at the front and back of the eye. They can help spot possible signs of eye disorders. 4. Discussing Your Results Your ophthalmologist will review the results with you after the examination. If your vision has changed, they may suggest new prescription lenses. If they spot an eye condition or another issue, they could recommend further testing, further monitoring, or treatment. It is also a good chance to ask questions regarding your eye health and the recommended follow-up care. What Should You do to Get Ready for your First Eye Examination? Having an eye examination usually involves nothing complicated. It is a good idea to take with you your present glasses or contact lens details and to be ready to give a list of any medications as well as any applicable medical or family history. Additionally, it might be helpful to remember any vision changes or symptoms you have had. Dilation may occur during the examination if certain tests are performed. After dilation has been advised, your vision might be temporarily blurred or more sensitive to light. Supporting Healthy Vision The initial eye examination is a valuable chance to determine a baseline for your eye health and understand your specific vision needs. Regular eye exams help monitor changes over time and support early detection of possible eye conditions. Plan a visit with an eye care professional if you have discovered any changes in your vision or if you're due for a check-up.

Children’s Vision Milestones: What Parents Should Watch For

August 28, 2026
Healthy vision is essential for a child's development, learning, and daily activities. From recognizing faces in infancy to reading, participating in sports, and navigating school, children depend on their eyesight to interpret and relate to their environment. Knowing typical vision milestones helps parents spot possible issues and seek appropriate care when needed. How Does Vision Develop in Children? Vision develops rapidly during the first years of life. Newborns perceive light, shapes, and nearby objects, although their vision remains immature. As children mature, their capacity to focus, track moving objects, recognize details, and coordinate both eyes improves progressively. Due to the gradual nature of visual development, regular eye examinations are essential. Certain childhood vision problems may not be readily apparent, especially when one eye is stronger than the other. Although each child develops at an individual pace, several general vision milestones may guide parental observation. 1. Infants: Birth to 12 Months Within the first year, infants typically develop the ability to focus on faces and objects, visually track moving items, and reach for objects they observe. Caregivers may also observe infants responding to known faces and visually exploring their environment. If an infant does not track objects, exhibits eyes that frequently cross or wander, or fails to respond visually to people or objects, these concerns should be discussed with a pediatrician or eye care professional. 2. Toddlers: Ages 1 to 3 As children become more active, their visual skills continue to develop. Toddlers rely on vision to walk, climb, manipulate small objects, and interact with toys. Over time, they typically improve in identifying familiar people and objects and in coordinating eye and hand movements. Frequent eye rubbing, squinting, sitting close to screens, or difficulty seeing objects could indicate the need for an eye exam. 3. Preschool and School-Age Children By preschool and early elementary school, children utilize vision for detailed activities including coloring, drawing, letter recognition, reading, and participating in games. Effective eye coordination and focusing abilities support learning and classroom performance. Children may not always realize their vision differs from other children’s, so parents should watch for signs such as headaches, avoiding reading, losing their place while reading, holding books unusually close, or struggling to see the board. Signs of Possible Vision Problems Caregivers should monitor for changes in a child's vision or behavior. Potential warning signs include: Frequent squinting or eye rubbing Eyes that cross, wander, or do not move together Complaints of blurry or double vision Frequent headaches Difficulty reading or concentrating Sitting very close to a television or screen Tilting or turning the head to see Covering or closing one eye Difficulty recognizing objects or seeing at a distance Avoiding activities that require close or distance vision If you notice these signs, speak with a pediatrician or eye care professional. The Importance of Children’s Eye Exams Regular eye examinations can identify vision problems before they interfere with learning and development. Eye care professionals assess visual acuity, binocular coordination, and common childhood eye conditions. Early detection matters because some vision problems are easier to address when identified in childhood. Parents must follow their child’s healthcare provider's recommendations for vision screenings and comprehensive eye exams. Helping Protect Your Child’s Vision Caregivers can promote healthy vision by encouraging beneficial habits. These include spending time outdoors, taking regular screen breaks, using appropriate protective eyewear during activities, maintaining a balanced diet, and attending recommended pediatric and eye care appointments. Supporting Healthy Vision at Every Age Knowing children's vision milestones helps caregivers distinguish typical development and spot possible issues early. Throughout infancy and the school years, monitoring how a child sees, focuses, and interacts with their environment is vital for supporting healthy development.  If you notice concerns about a child's eyesight or alterations in vision, consult a healthcare provider or eye care professional. Early attention to vision supports learning, development, confidence, and overall quality of life.

The Connection Between Diabetes and Eye Health

July 29, 2026
Diabetes affects various parts of the body, including your eyes. Keeping your blood sugar under control is not just good for your health overall, but it also helps protect your eyesight. Over time, high blood sugar can irritate the tiny blood vessels in your eyes and increase your risk of serious eye problems. Knowing how diabetes and eye health are linked can help you identify issues and take measures to protect your sight. How Does Diabetes Affect Eye Health? When blood sugar stays high, it can damage the blood vessels in the retina, which is the part of your eye that senses light and helps you see. Damaged blood vessels might leak fluid, swell, or change how well the retina works. Diabetic eye problems usually develop slowly, so you might not pick up on any changes in your vision until significant damage has occurred. That’s why it’s important for people with diabetes to get regular eye exams, even if their eyesight seems fine. Common Eye Conditions Linked to Diabetes People with diabetes are more likely to have certain eye problems. Finding and treating these issues early can lower the chance of losing vision permanently. 1. Diabetic Retinopathy Diabetic retinopathy is a common eye issue that happens when high blood sugar damages the retinal blood vessels. These damaged vessels may leak fluid, which may cause blurry vision, dark spots, or changes in how you see. In advanced cases, abnormal blood vessel growth can lead to serious problems. If diabetic retinopathy worsens, new abnormal blood vessels can grow, causing serious problems, including vision loss. Getting regular eye exams can help catch these changes early, before they become severe. When fluid is retained in the macula (part of the retina which focuses on sharp central vision), this swelling can make it harder to read, recognize faces, or see fine details clearly. When detected early, treatments can help reduce swelling and protect your eyesight. 3. Cataracts People with diabetes have a higher chance of getting cataracts early. Cataracts occur when the lens in your eye becomes cloudy, which can cause blurry vision, increased sensitivity to glare, and difficulty seeing clearly. While cataracts come with age, having diabetes can make them appear sooner or progress quicker. 4. Glaucoma Diabetes can also raise your risk for glaucoma, which is a group of eye diseases that harm the optic nerve. Glaucoma usually starts without any clear symptoms, but if it is not treated, it can cause permanent vision loss. Routine regular eye exams are important for finding glaucoma early and keeping your eyes healthy Diabetes-related eye problems might not cause symptoms at first. Still, there are some warning signs you should look out for: • Blurry or distorted vision • Difficulty focusing • Dark spots, floaters, or shadows in your sight • Increased sensitivity to glare • Trouble seeing colors clearly • Sudden alterations in vision • Partial or complete loss of vision If you notice sudden vision changes, contact an eye doctor as soon as possible. The Value of Regular Eye Exams for People With Diabetes Getting a full eye exam is one of the best ways to protect your vision if you have diabetes. During the examination, your physician will study your retina, look for symptoms of diabetic eye disease, and track any changes over time. Many eye problems linked to diabetes can be treated more easily if they are found early. Regular checkups help your eye doctor give you advice that fits your own eye health and diabetes care. Protecting Your Eyes When You Have Diabetes Looking after your general health is important for keeping your eyes healthy. Here are some things you can do to protect your vision: • Keeping blood sugar levels under control • Managing blood pressure and cholesterol • Scheduling regular diabetic eye exams • Following your diabetes treatment plan • Eating a balanced diet that promotes eye health • Avoiding smoking, which increases the risk of eye complications Prioritizing Your Vision and Eye Health Diabetes and eye health are closely linked, but you can lower your risk of serious vision problems by taking action early. Getting regular eye exams, making healthy choices, and managing your diabetes all help protect your eyesight. If you have diabetes, seeing your eye doctor regularly can help catch changes early and keep your vision clear for the future. Your eyes are a key part of your health, so make caring for them a priority at every age.
