Cataracts and glaucoma are two common eye conditions that can significantly impact your quality of vision. If you or a loved one are concerned about either condition, early detection and treatment are key in maintaining proper eye health and preventing the condition from worsening. In this article, learn the key differences between cataracts and glaucoma and discover tips for protecting your eyes from long-term vision loss.

What is Glaucoma?

Glaucoma refers to a build-up of fluids within the eye that causes damage to the optic nerve, or the part of the eye that sends signals to the brain and allows you to see the objects in front of you. This fluid build-up puts excessive pressure on the eye and can lead to irreversible vision loss, according to the Cleveland Clinic. While the most common type is open-angle glaucoma, other less common types, like narrow-angle glaucoma and congenital glaucoma, can be equally problematic.

Glaucoma can be hereditary, but it can also be caused by eye injury or another pre-existing health condition. Usually, the first signs of glaucoma are difficult to spot because symptoms happen over the course of many years. Because the course is so gradual, immediate changes in vision often go unnoticed. However, warning signs of glaucoma can include:

  • Pressure or pain in one or both eyes
  • Frequent headaches
  • Seeing halos around lights
  • Blind spots or low vision
  • Blurred eyesight or tunnel vision
  • Nausea
  • Red eyes1

What Are Cataracts?

A cataract is an eye disorder in which the fibers and proteins that make up the lens’ tissue break down and form a cloudy film. This can happen because of an injury to the lens’ tissue, but simple aging is the most common cause because our eyes’ lenses become thicker and less flexible as we age, and thus are more prone to injury. Like glaucoma, cataracts can also be hereditary.

Symptoms typically develop over time and do not immediately affect eyesight. Warning signs of cataracts, according to Mayo Clinic, can include:

  • Clouded or blurred vision
  • Double vision in one eye
  • Trouble with nighttime vision
  • Colors appearing faded or yellowish
  • Light sensitivity
  • Seeing halos around lights
  • Frequent changes to eyeglasses or contact lens prescriptions2

Glaucoma vs. Cataracts: Key Differences

Glaucoma and cataracts share similar symptoms, but they have vastly different effects. If you or a loved one is concerned about cataracts or glaucoma, learning what makes each condition unique can help you spot the warning signs and determine the next steps.

The following are noteworthy differences between glaucoma and cataracts, according to the Glaucoma Research Foundation:

  • Effect. Whereas glaucoma affects the optic nerve causing excessive pressure within the eye, cataracts affect the eye’s lens causing cloudy or blurred vision.
  • Severity. Cataracts aren’t considered an emergency medical condition. Glaucoma, however, is more urgent, requiring early detection and treatment.
  • Permanence. Cataracts’ effects can be reversed with surgery. Unfortunately, any vision loss due to glaucoma is permanent; however, surgery can help treat symptoms and prevent the condition from worsening.
  • Treatment. Glaucoma laser surgery is a much different procedure than that of eye surgery for cataracts. While cataracts surgery involves removing the clouded lens and replacing it with an artificial one, glaucoma surgery involves either opening the blocked canals within the eye to prevent further blockage or creating new drainage paths to the outside of the eye.3

10 Tips for Protection Against Cataracts and Glaucoma

Help your loved one protect their vision from cataracts and glaucoma long-term with these senior eye health tips from the American Academy of Ophthalmology:

  1. Stay up to date on routine eye exams. One of the best things you can do to stay ahead of eye conditions is to attend routine screenings—whether you’re already coping with vision loss or you’re wanting to prevent it. At an eye exam, the doctor will thoroughly examine each eye for signs of damage or disease to catch cataracts or glaucoma as soon as possible.
  2. Know your risk factors. Talk with a doctor about potential factors that may put you or your loved one at higher risk for developing glaucoma or cataracts.

Risk factors for cataracts include:

  • Increasing age
  • Excessive smoking and alcohol use
  • Diabetes
  • Long-term use of corticosteroids
  • Previous eye injury or surgery
  • Family history of cataracts2

Risk factors for glaucoma include:

  • Farsightedness or near sightedness
  • High or low blood pressure
  • Diabetes
  • Long-term use of corticosteroids
  • Previous eye injury or surgery
  • Family history of glaucoma1
  1. Keep your blood pressure and blood sugar levels in check. A plate full of colorful fruits and vegetables is a great defense against vision loss. These foods are rich in vitamins and minerals that contribute to happy, healthy eyes.
  2. Exercise mindfully. When your heart rate increases during strenuous activity, the pressure in your eyes also increases. When exercising, keep an eye on your heart rate and stop to rest frequently. Moderate exercise like a brisk walk is a safe option to move your body while protecting your eyes.
  3. Wear eye protection when appropriate. Be sure to use protective eyewear when doing chores that involve strong chemicals or flying debris—doing so can reduce the risk of eye injury by 90%. 4
  4. Wear sunglasses when outside. When selecting sunglasses, it’s best to choose ones with large, polarized lenses that offer 100% UV protection. Most drug stores offer plenty of affordable yet effective options.
  5. Avoid upturned positions. Placing your head below your heart for extended periods of time raises the pressure in your eyes, which can increase the risk for glaucoma. Try to avoid using items like inversion tables or gravity boots, as well as certain head-down yoga positions.
  6. Treat any sleep conditions, especially obstructive sleep apnea (OSA). When left untreated, sleeping disorders like OSA can sometimes lead to more serious health problems, including glaucoma and other eye conditions. Make sure you address any sleep concerns with a doctor and get a good night’s rest.
  7. Take care of your oral health. Some studies indicate that there may be a connection between gum disease and eye health. Be sure to keep up with your regular dental screenings, and brush and floss your teeth at least twice a day.
  8. Tell your eye doctor about any medications you’re taking. Blood pressure medicine and steroids can worsen glaucoma damage. Talk to your doctor candidly about any medications or supplements you’re taking so they can provide you with the most effective eye care. 5

Naples Clinic Expands to Provide Free Medications for Low-Income Workers

For low-income Collier County residents who are working but uninsured, access to the medications they need is not as easy as going to a regular chain pharmacy to pick them up. Thats where the Neighborhood Health Clinics expanded non-narcotic medication room comes in, giving patients managing chronic conditions including hypertension and diabetes timely access to medications at no cost. The 1,850-square-foot medication room, located at the clinic on Goodlette-Frank Road near Central Avenue, was built at a cost of $500,000 and is named for the late Stacy Forman, a Naples philanthropist who donated funding for the expansion.Keith Maples, CEO of Neighborhood Health Clinic, said the expanded medications facility enhances the clinics ability to serve patients faster and more efficiently. On a typical day, a patient can walk in and when they walk out, theyre walking out with thousands of dollars worth of medication that, if it were outside of the Clinic, they would not be able to fill those prescriptions because it would be outside of what they could afford, Maples said. He said the expanded space, equipped with updated technology and increased storage capacity, allows for a larger inventory of non-narcotic medications that enables the Clinic to fill prescriptions immediately to minimize delays in treatment. In 2024, the Clinic distributed $6.5 million in retail value of medications thanks to partnerships with Americares, Direct Relief, Dispensary of Hope and other pharmaceutical companies. The expansion allows us to work even more with our pharmaceutical partners to basically procure all of the medications necessary for our patients, Maples said. He said that many patients arriving at the Clinic for the first time have not previously received medical care for the condition needing treatment and may have vastly elevated blood pressure or blood sugar levels, for example.  When they walk through the doors, theyre at such a heightened level that were trying to bring it back to a controlled number to where its manageable for them, Maples said. If their A1Cs are through the roof, their [blood] sugars are through the roof, were trying to get them back to an established number that helps them feel better. Well never cure them of all those illnesses, but well maintain that health for them, so they feel better and have a better quality of life.Clinic grows to meet patient demand The nonprofit Neighborhood Health Clinic was established in 1999 by Dr. Bill and Nancy Lascheid to provide medical care to low-income, working but uninsured Collier County adults. Their daughter, Leslie Lascheid, now serves as president of the organization. In 2024 the clinic saw more than 12,000 patient visits and delivered more than 30,000 patient procedures, Maples said, with all medications, primary care, specialty care, surgeries and outpatient procedures provided free of charge to patients.All funding is through philanthropy, as the Clinic does not receive any city, county, state or federal funding including Medicaid or Medicare. Over the years the clinic has expanded as the patient load has increased. The original 11,000-square-foot facility more than doubled in size with the completion of the Armstrong Medical Specialties Building in 2021, which expanded the campus to 23,000 square feet.  The addition of the Van Domelen Education and Wellness Building, also in 2021, took the total to its current 32,000 square feet, and when the Bill and Candy Raveis Pathology Building is completed this summer, the total campus will be at 43,000 square feet, according to Marcie Berland, the Clinics director of development. Maples said the Clinic has expanded strategically over the years to meet the medical needs of patients many of whom work in hospitality, service or construction industries in Collier County and the growing volume of patient visits. When weve expanded, we didnt do it just to do it, he said. We based it on what were the patient needs and what do we need in-house on a daily basis to deliver the care, providing the opportunity for a patient to walk in the door, get all the care they need and not have to go to another location somewhere else, or come for another appointment. Because when our patients miss days of work, thats food on the table and the roof over their heads. Its not like if I call in sick: I get a sick day and still get paid.  He said the campus expansions allow most procedures including lab work to be done in-house, creating opportunities for sustainable, uninterrupted patient care. When that patient walks through the doors, I never want them to wonder where theyre going to get their care or how theyre getting to their next appointment, Maples said. Many of our patients get rides here, or they walk or ride their bikes, because very few own cars that they can drive in.  And while the Clinic does have a full-time paid staff of 14 and five part-time staff, no medical professionals are paid to deliver care, Maples said. More than 250 physicians, 50 dentists, 100 nurses and 300 non-medical personnel deliver care and provide patient education on a volunteer basis. 

Beyond the Surface: Naples Cancer Advisors Spotlight Melanoma During Awareness Month

Beyond the Surface: Naples Cancer Advisors Spotlight Melanoma During Awareness MonthMay 1, 20256 Min ReadBy Jillian Hunt, CNP Executive Director of Clinical Operations at Naples Cancer AdvisorsMay is Melanoma Awareness Month, and in sun-drenched Collier and Lee Counties, its more than a calendar observance. Its a call to action. The sunny environment increases exposure to ultraviolet (UV) rays, which are a significant risk factor for skin cancer, including melanoma. Understanding the risks and adopting preventive measures can help residents enjoy the sun safely while minimizing their skin cancer risk.At NCA, we specialize in delivering second opinions and expert oncology guidance at no cost to patients. Our team, including nationally recognized oncologist Dr. Philip Leming, believes that no one should face a cancer diagnosis alone. This month, we want to shine a light on reshaping melanoma prevention, detection, and awarenessso you can stay protected and proactive.Prevention: A Daily Practice, Not Just a Summer ChecklistMost people know the basics: use sunscreen, avoid tanning beds, cover up when outside. But melanoma doesnt just show up where the sun shines. It can develop under your fingernails, between your toes, even on your scalp or eyes. We educate patients to look everywhere, not just the obvious spots.One powerful (and often overlooked) fact: a single blistering sunburn in childhood doubles your lifetime risk of melanoma. Thats why prevention is a family affair. We urge parents to build sun safety habits early and keep them consistent all year.Detection: A Watchful Eye is The Best ToolThe front line of defense against skin cancer is early detection. Identifying skin changes especially changes in moles is the easiest way to catch skin cancer earlier.What is a mole?A mole is a benign (non-cancerous) growth on the skin that develops when melanocytes, the cells responsible for producing pigment, cluster together instead of being evenly distributed. Moles can be present from birth or develop later in life.ABCDEs of Moles and Melanoma Detection Asymmetry: One half of the mole doesnt match the other. Border irregularity: The edges of the mole are uneven, ragged, or notched. Color variation: The mole has multiple shades of brown, black, or other colors like red, white, or blue. Diameter: The mole is larger than 6 millimeters (about the size of a pencil eraser). Evolving: The mole has changed in size, shape, or color, or has new symptoms like itching, bleeding, or crusting.The ABCDEs are a helpful tool for self-examination and can prompt individuals to seek professional medical advice if any of these signs are present.Dermatologists remain the front line in detection and diagnosis. However, emerging technologies are offering exciting backup. Artificial intelligence skin scanners and total body imaging are improving the speed and accuracy of diagnosis.Whether its through advanced tools or a trained eye, one truth remains: catching melanoma early saves lives.The NCA Difference: Compassionate, Cost-Free Cancer GuidanceNaples Cancer Advisors was founded to be a bridge for patients who feel lost, overwhelmed, or unsure where to turn after a cancer diagnosis. We offer a second set of expert eyes, help explain treatment options, connect people to top-tier providers, and support them throughout their journey.Melanoma may be aggressive, but its also highly preventable and treatable when caught early. This May, we urge everyone in our community to schedule a skin check, learn your ABCDEs (Asymmetry, Border, Color, Diameter, Evolving), and take sun safety seriously.And if you ever need clarity or support after a diagnosis, Naples Cancer Advisors is herefree, local, and fully focused on you.Jillian Hunt, CNP BioJillian has been caring for cancer patients since 2004.
