Causes & Symptoms Of Cataract Related Eye Conditions

Baptist Eye Surgeons • August 20, 2018

Causes & Symptoms Of Cataract Related Eye ConditionsThe eye’s crystalline lens sits is located just behind the pupil and functions along with the cornea to focus light on the retina. As we age, proteins in this crystalline lens clump together, which creates clouding and hardening of the lens that can eventually affect our vision. This clouding is considered a cataract, whether there has been a significant reduction vision or not. The most common symptoms of cataracts are blurring and dimming of vision. Let’s take a closer looks at causes, symptoms, and treatments of cataracts:

What Causes Cataracts?

Cataracts are quite common. In fact, the National Eye Institute (NEI) estimates that there will be up to 50 million cataract diagnoses in the U.S. by 2050. Around age 40, the normal proteins in the eye’s lens start to break down and clump together, which is what causes clouding and hardening of the lens over time. Those over age 60 usually start to have some clouding of their lenses, although vision problems may not be apparent until years later.

Other factors that increase the risk of developing cataracts include:

  • Heredity: risk increases if other family members have cataracts.
  • Health: certain medical problems, such as diabetes, increase risk of cataracts.
  • Having had an eye injury, eye surgery, or radiation treatments on your upper body.
  • Sun exposure, especially without sunglasses that protect your eyes from damaging ultraviolet (UV) rays.
  • Using certain medications such as corticosteroids, which may cause early formation of cataracts.

Most age-related cataracts develop gradually over time as people age. For others, such as people with diabetes or younger people, cataracts can develop more rapidly. Ophthalmologists cannot predict how quickly a person’s cataract will develop.

What Are The Symptoms of Cataracts?

The main symptoms of cataracts are shared with many other eye conditions, so a complete eye examination including dialysis is required to ensure a proper diagnosis of cataracts. As mentioned, cataracts usually begin forming before any vision problems are apparent. Once cataracts begin to affect vision, you may experience:

  • Blurry vision
  • Dimmed vision, bright colors appear faded or yellow
  • Double vision in one eye only
  • Increased sensitivity to light
  • Seeing halos around lights
  • Difficulty seeing at night
  • Needing more light when you read
  • Decreased depth perception

Prevention & Treatment of Cataracts

If you have cataracts or know that you’re at a higher risk of developing them, you may be able to slow down the progression of your cataracts. Protecting your eyes from sunlight is the best way to do this. Wear sunglasses that protect your eyes by screening out the sun’s ultraviolet (UV) light rays. You may also wear regular eyeglasses that have a clear, anti-UV coating. Talk with your eye doctor about the options that are best for you.

When you begin experiencing any of the symptoms above and you decide it’s time to seek treatment for your cataracts, the first step will be for an ophthalmologist to do a comprehensive eye examination to evaluate the exact extent and nature of your cataracts. The ophthalmologist will examine the front part of your eye, including the lens, with a biomicroscope, also called a slit lamp. He or she will also examine the back of your eye with an ophthalmoscope.

Surgery

Fortunately, cataract surgery is as common as the condition itself, and is typically very successful for restoring vision. During cataract surgery, the eye surgeon will remove the cloudy and hardened lens and replace it with an artificial lens called an intraocular lens(or IOL). Depending on your vision, a specific intraocular lens may be used to correct other distortions in vision, such as nearsightedness or farsightedness. If this is the case for you, having cataract surgery may reduce or even eliminate your dependence on corrective eyeglasses.

Will I Still Need Glasses?

Many people who have cataract surgery will still need to wear glasses after the sight-saving procedure. Studies show that 30 to 50 percent of people who have cataract surgery still need glasses after surgery. However, a new kind of artificial lens recently approved by the FDA could help more people get rid of their glasses after cataract surgery.

During standard cataract surgery, the IOL replaces the eye’s natural lens, and functions to bend, or refract, light rays that enter the eye to help you see correctly.

Your eye surgeon will make careful measurements of your eye to perform surgery precisely with the intention that your vision will be fully corrected. However, 20/20 vision without glasses isn’t always achievable after surgery because the surgeon can only estimate where the new lens will fit in the eye after it heals from surgery.

Determining exactly where in the eye the new lens will end up once the eye heals determines how close the surgeon restore 20/20 vision without glasses. However, a new lens—a light-adjustable intraocular lens or RxLAL—that the FDA recently approved may solve this problem. This is not available yet but hopefully will be soon.

This unique lens will allow ophthalmologists to apply your prescription directly into the lens after your eye has healed from surgery. This is done by applying a low-intensity beam of ultraviolet light from a specialized light delivery device. Because the lens is made of a photoreactive silicone material, the light beam is able to subtly change the shape of the surface of the lens, which could correct any vision problems still existing after cataract surgery.

The FDA study showed that approximately twice as many patients had 20/20 vision restored after this RxLAL procedure compared to standard IOLs. Your eye doctor will discuss which surgical procedure is best for you. Regardless, rest assured that even though cataract surgery is a complex procedure it’s also a very common procedure.

Baptist Eye Surgeons has several eye surgeons who specialize in cataract implant surgeries. All cataract surgeries are performed on an outpatient basis, allowing for us to safely perform the procedure while limiting the impact on your daily routine as much as possible. While it usually takes several weeks for your eye to fully heal, most patients are able to return to office-type work within a few days and to manual labor after one week.

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.
