Most of us don’t consider getting an eye exam until we think we need new glasses or maybe when we think we need glasses for the first time. But that’s not the only reason we should be visiting the eye doctor. For adults, maintaining eye health becomes increasingly important as we get older. Vision changes are a natural part of aging and many serious eye conditions can be managed or even prevented with regular care. Conditions such as cataracts, glaucoma, macular degeneration, and diabetic retinopathy can be discovered during routine exams. Additionally, there are rarer eye conditions that can be detected, such as ocular cancers, that may not be symptomatic initially but can lead to vision loss and can even be fatal.
Timely diagnosis and treatment of eye diseases are crucial to preserving sight and overall quality of life. Your eye exam is about far more than just a new pair of glasses.
This issue will cover major eye diseases affecting adults, the symptoms, available treatments, and complications of late diagnoses.
Cataracts
A cataract is a clouding of the eye’s natural lens, leading to blurry or diminished vision. Cataracts are one of the most common causes of vision loss in older adults.
Symptoms:
- Blurred or cloudy vision
- Difficulty seeing at night
- Sensitivity to light and glare
- Seeing halos around lights
- Fading or yellowing of colors
- Double vision in one eye
Treatment:
In the early stages, stronger lighting and prescription glasses may help. However, the only definitive treatment is cataract surgery, where the cloudy lens is replaced with an artificial intraocular lens (IOL). Cataract surgery is one of the safest and most effective procedures available.
Complications of Late Diagnosis:
Delaying treatment can lead to significant vision impairment, increasing the risk of falls, depression, and loss of independence. In advanced cases, cataracts can cause complete blindness.
Glaucoma
Glaucoma is a group of diseases that damage the optic nerve, often due to high intraocular pressure. Open-angle glaucoma is the most common form. It typically develops slowly without noticeable symptoms. Angle-closure glaucoma appears more suddenly and generally involves severe eye pain. Glaucoma is a leading cause of blindness worldwide and often develops without noticeable symptoms until significant vision loss occurs.
Symptoms:
- Gradual loss of peripheral vision (in open-angle glaucoma)
- Sudden, severe eye pain (in angle-closure glaucoma)
- Blurred vision
- Halos around lights
- Nausea and vomiting (in acute cases)
Treatment:
Glaucoma cannot be cured, but it can be managed with:
- Prescription eye drops to reduce intraocular pressure
- Laser therapy to improve fluid drainage
- Surgery in severe cases
Complications of Late Diagnosis:
Glaucoma-related vision loss is irreversible. Without timely intervention, glaucoma can lead to tunnel vision and complete blindness.
Age-Related Macular Degeneration (AMD)
Macular degeneration, or age-related macular degeneration (AMD), primarily affects the macula, the central part of the retina responsible for sharp, central vision. There are two main forms of AMD: dry (non-neovascular) and wet (neovascular). Dry AMD is more common and progresses slowly, while wet AMD is less common but more severe and leads to rapid vision loss.
Symptoms:
- Blurred or distorted central vision
- Difficulty reading or recognizing faces
- Straight lines appearing wavy
- Need for brighter light when reading
- Dark or empty areas in the center of vision
Treatment:
There is no cure for AMD, but treatment options include:
- Injections to slow the progression of wet AMD
- Laser therapy in some cases
- Lifestyle changes, including a diet rich in leafy greens, omega-3 fatty acids, and antioxidant supplements
Complications of Late Diagnosis:
Without early treatment, AMD can progress to severe vision loss, making everyday activities like reading and driving difficult.
Diabetic Retinopathy
This condition occurs in people with diabetes when high blood sugar damages the blood vessels in the retina. In early stages it is not symptomatic, but it can lead to blindness if untreated.
Symptoms:
- Floaters or dark spots in vision
- Blurry vision
- Difficulty seeing colors
- Vision loss in advanced cases
Treatment:
- Better blood sugar control to slow progression
- Injections to prevent spread
- Laser treatment to seal leaking blood vessels
- Surgery for severe cases
Complications of Late Diagnosis:
Delaying treatment can result in retinal detachment, complete vision loss, and an increased risk of other eye diseases.
Cancers of the Eye
Although rare, cancers such as ocular melanoma can develop in the eye. This is a diverse group of malignancies that can affect different parts of the eye and its surrounding structures. They can originate within the eye or can spread to the eye from other parts of the body. They can be aggressive and vision threatening requiring prompt diagnosis and treatment.
Symptoms vary depending on the type and location of the cancer and can include many of the same symptoms as other eye diseases. Prognosis and treatment depend on the type of cancer and stage at the time of diagnosis. Treatment can include surgery, radiation therapy, laser therapy, chemotherapy and targeted immunotherapy. Early diagnosis is critical.
The Importance of Regular Eye Examinations
The American Academy of Ophthalmology recommends that adults over 65 have a comprehensive eye exam at least once a year, even if they have no noticeable vision problems. Those with conditions like diabetes, glaucoma, or AMD may need more frequent exams.
Maintaining Good Eye Health
- Eat a Vision-Friendly Diet: Foods rich in vitamin A, C, E, zinc, and omega-3 fatty acids help protect eyesight.
- Control Chronic Conditions: Managing diabetes and high blood pressure reduces the risk of eye complications.
- Protect Your Eyes: Wear sunglasses with UV protection and blue light filtering when using digital screens.
- Quit Smoking: Smoking significantly increases the risk of AMD, cataracts, and other eye diseases.
- Stay Active: Regular exercise improves circulation and overall eye health.
- Use Proper Lighting: Ensure good lighting at home to prevent strain and falls.
- Follow Medication Instructions: Use prescribed eye drops and medications consistently to manage conditions like glaucoma.
Prioritizing Eye Health for a Better Quality of Life
Vision loss can significantly impact independence, mobility, and mental well-being. The key to maintaining good eye health is early detection and timely treatment. By scheduling regular eye exams and adopting healthy habits, you can preserve your vision and enjoy a higher quality of life.
If you’re haven’t had an eye exam in the past year, now is the time to schedule one. It’s about more than just a new pair of glasses. Protecting your eyesight today can ensure a clearer, brighter tomorrow.











Don’t Forget Climate Change

It Affects Us All
Climate change, one of the most critical challenges facing humanity in the 21st century, seems to be forgotten in all the controversy surrounding DOGE. Regardless of everything else going on, we can’t ignore climate change because it affects global temperatures, weather patterns, ecosystems, and economies. The overwhelming scientific consensus is that human activities—primarily the burning of fossil fuels—are driving climate change.
The existence of climate change and the impact of human activity, like any other field of science, includes areas of disagreement among researchers. One of the principal areas of disagreement is about the sensitivity of the climate to the increase in CO2 production and the rate at which global warming will occur. There’s also discussion about how effective climate models may be with some arguing that the models may either overestimate or underestimate certain effects. A significant area of disagreement is over what is known as the “tipping points”. This is a debate about when or if certain events such as ice sheet collapse, permafrost thaw or ocean circulation changes might occur. Some argue these events could trigger rapid self-reinforcing climate shifts while others believe changes will be more gradual. Even with this disagreement there is broad acceptance that climate change has increased the frequency and intensity of heat waves, heavy rain and extreme weather.
As intense as some of these scientific debates maybe, they pale in significance beside the political debates being generated around climate change.
When the possibility of climate change was first recognized in the 1970s and 1980s there was bipartisan support to address possible remediation of long-term impacts. Republican President Richard Nixon signed landmark environmental laws including the Clean Air Act.
During the 1990s climate change became more polarized. President George H. W. Bush begin to frame climate change policy as an economic threat. George W. Bush rejected the Kyoto Protocol to avoid “economic hindrance”.
By 2008 the partisan divide had significantly increased. Republicans increasingly dismissed climate risks while Democrats amplified the urgency of taking action. By 2023, 78% of Democrats prioritized climate policy, but only 21% of Republicans viewed climate action as urgent despite increasing climate risks in some GOP dominated states such as Florida and Texas.
The partisan gap expanded as conservative science skeptics continued to raise issues about rates of change, economic impacts and potential solutions. These conservatives tend to view climate policies as government overreach, while progressives hold the position that the government led initiatives are essential to combat environmental threats.
As they have in many other issues, the media have lined up into conservative and progressive camps. The conservative leaning media downplays climate risks while the liberal leaning media emphasizes the danger and need for urgent action. As with many other things this leads to a “echo chamber” effect simply reinforcing political beliefs without adding anything new of significance to the debate.
The Trump administration has signaled its desire to undo many of the climate change initiatives put in place by Democratic administrations. On January 20, 2025, President Trump signed Executive Order 14162 directing the immediate withdrawal of the United States from the Paris Climate Agreements and related international climate commitments. He has declared a “National Energy Emergency” to accelerate fossil fuel development and ease restrictions on the construction of new oil and gas projects. As part of this effort, he has weakened environmental reviews. This is expected to significantly increase fossil fuel consumption and associated greenhouse gas emissions. The Trump administration has begun the rollback of environmental regulations. Lobbyists for the oil, gas and chemical industries have been appointed to the Environmental Protection Agency to reverse climate regulations and pollution controls.
The administration is withdrawing funding for clean energy initiatives including those aimed at reducing carbon emissions and promoting renewable energy resources. The administration has initiated a review of the “legality and continued applicability” of the EPA’s endangerment finding which is the basis of most federal regulations on greenhouse gas. The administration rolled back regulations limiting methane emissions from oil and gas operations. The definition of “waters of the United States” under the Clean Water Act was narrowed, potentially allowing increased pollution in streams and wetlands.
We can expect increases in severe weather because of Trump’s environmental policies. These policy decisions collectively hinder efforts to mitigate climate change, potentially leading to increased greenhouse emissions and global warming. Reduction in funding for climate change research and the rollback of environmental regulations will have long term adverse effects on both domestic and global environmental health.
Significant budget cuts and layoffs within agencies like the National Oceanic and Atmospheric Administration (NOAA) could impair the ability to forecast and respond to severe weather events. For instance, the reduction of meteorologists and environmental scientists may hinder critical forecasting services, affecting public safety during events like hurricanes, tornados and floods.
The U.S. withdrawal from international climate initiatives, such as the Loss and Damage Fund, reduces financial support for developing countries dealing with climate-induced disasters. This could lead to inadequate infrastructure and preparedness in vulnerable regions, potentially increasing the severity of weather-related impacts.
While it is challenging to attribute specific future weather events to current policy changes directly, the administration’s environmental policies will likely contribute to conditions that favor more frequent and intense extreme weather events. The combination of increased greenhouse gas emissions together with weakened environmental regulations, reduced climate research capabilities, and diminished global climate cooperation collectively enhance the likelihood and impact of severe weather phenomena. This damage to our environment needs to be prevented! Once it occurs it will be difficult to ever reverse and our children and grandchildren will suffer as a result.
