Many people expect their eyesight to decline with age — perhaps requiring a stronger eyeglass prescription or “readers.” Some vision changes are linked to age, but there are steps to consider to help our eyes stay as healthy as possible.
Dr. Linda Chous, OD, chief eye care officer, UnitedHealthcare, answered the following questions:
1. Are my eyes going to keep getting worse as I age?
While your eyesight is not guaranteed to deteriorate with age, it is normal to notice changes to your vision as the years pass, including:
- Minor adjustments to your eyeglasses prescription or needing to use “readers” for the first time;
- Trouble distinguishing colors, such as blue from black; and
- The need for more light to see well.
Although these changes are often normal, they can also be signs of conditions like cataracts or even diabetes. It is important to maintain regular appointments with your eye doctor to help identify pressing concerns. If you experience sudden vision loss or any rapid change to your eyesight, contact your eye care provider immediately.
2. What are the tiny spots or specks that float across my vision?
These tiny threads of protein float across the gel-like substance between your eye’s lens and retina.
Usually there is no need to worry if you notice these spots occasionally and they disappear after a few minutes, but only a dilated eye examination can determine the cause of the “floaters.”
If your vision is overcome by these specks or you notice vision loss, contact your eye doctor, as it could be a symptom of a sight-threatening condition.
3. What are some common vision-related diseases that come with age?
Age-related macular degeneration (AMD)
AMD is the leading cause of vision loss in people over 65. AMD causes damage to the macula, the small spot on the retina that enables people to see clearly and view things straight ahead of them.
Common symptoms are distortion and blurring of the center of your field of vision. If caught early, there are potential benefits from certain prescription medications and nutritional supplements. Late-stage AMD is much more difficult to treat.
Certain factors like heredity, ultraviolet light exposure and smoking may increase the risk of AMD. Consult with your eye doctor to determine if a preventive treatment plan is right for you.
A cataract is the clouding of the lens in your eye, blocking the flow of light to the back of your eye (retina), which ultimately causes loss of sight. Most form slowly and do not cause pain. Significant clouding can form in some people and, ultimately, negatively impact vision.
Cataracts are treatable via surgery that replaces the clouded lens with a clear plastic lens. Cataract surgery is generally safe and one of the most common surgeries in the U.S. Once a cataract is removed, it cannot grow back.
Glaucoma is caused by increased pressure inside the eye, which can cause permanent vision loss and blindness if untreated. The most common form usually has no noticeable symptoms in the early stages — the only way to detect it is routine testing.
Treatment may include prescription eye drops, oral medications, laser treatment surgery or a combination of any of these. It is important to find glaucoma early because once vision is lost, it cannot be regained.
4. What are the best ways to keep my eyes healthy as I age?
Some of the best ways to protect your eyes include:
- Stop smoking. Smokers are up to four times more likely to develop AMD and may contribute to development of cataracts.
- Maintain a healthy weight. Conditions associated with being overweight, like diabetes and heart disease, increase your risk of vision loss from cataracts, glaucoma and retinopathy.
- Wear sunglasses. Help protect your eyes from harmful ultraviolet rays.
- Be physically active. People who are physically active experienced less vision loss over 20 years compared to those who are less active.
- Eat a healthy diet. Colorful fruits and vegetables contain nutrients that can keep your eyes healthy and reduce AMD risk.
5. Do sunglasses really protect my eyes?
Sunglasses act as a buffer between your eyes and the sun’s ultraviolet (UV) rays. Exposure to these rays can put you at greater risk of cataracts and AMD. Look for a pair that blocks 99% to 100% of UV rays.
Note that polarization is different from UV protection; however, most polarized sunglasses also provide UV protection. Check the product tag or ask for assistance in choosing the right pair.
6. How often should I see my eye care doctor?
Eye exams are crucial to maintaining eye health as you age. Many eye diseases, like glaucoma, have no symptoms in early stages. And many systemic conditions, such as diabetes and high blood pressure, can be first found during a routine eye exam. Aim to see your eye doctor annually even if your vision hasn’t changed, so your doctor has a record of your eye health. See your doctor immediately for sudden changes.
For UnitedHealthcare Medicare Advantage members, many plans include routine vision services as well as additional services not covered under Original Medicare. It’s helpful to learn how to take advantage of these and other benefits.
Plans insured through UnitedHealthcare Insurance Company or one of its affiliated companies, a Medicare Advantage organization with a Medicare contract. Enrollment in the plan depends on the plan’s contract renewal with Medicare.
Stockholm+50: Accelerate action towards a healthy and prosperous planet for all
The United Nations General Assembly agreed on the way forward for plans to host an international meeting at the highest possible level in Stockholm next June, during the week of World Environment Day. The event will commemorate the 50 years since the United Nations Conference on the Human Environment and serve as a contribution to accelerate action towards a more sustainable society.
The Declaration of the United Nations Conference on the Human Environment was made in 1972 in Stockholm, Sweden, resulting in what is often seen as the the first step toward the development of international environmental law, recognizing the importance of a healthy environment for people, and creating the UN Environment Programme (UNEP).
Five decades after the 1972 Stockholm Conference, the Government of Sweden, with support from the Government of Kenya, will host Stockholm+50, an international meeting in 2022 to commemorate the 50 years since the United Nations Conference on the Human Environment and its outcome documents, as a contribution to the environmental dimension of sustainable development to accelerate the implementation of commitments in the context of the decade of action and delivery for sustainable development, including a sustainable recovery from the coronavirus disease (COVID-19) pandemic.
The international meeting, “Stockholm+50: a healthy planet for the prosperity of all – our responsibility, our opportunity”, will take place in Stockholm on 2 and 3 June 2022, following a UN General Assembly resolution. In three leadership dialogues, the meeting will reflect on the urgent need for actions towards a healthy planet and prosperity of all, achieving a sustainable and inclusive recovery from the COVID-19 pandemic, and accelerating the implementation of the environmental dimension of Sustainable Development in the context of the Decade of Action. The meeting will also reinforce the messages and the outcomes of the event to commemorate UNEP’s 50th anniversary (UNEP@50), which will have taken place in March 2022, in Nairobi.
Per Bolund, Sweden’s Minister for the Environment and Climate, and Deputy Prime Minister, said “Our aim is clear, we want Stockholm+50 to make a concrete contribution to accelerating the transformation to a sustainable future. We call this meeting to commemorate the fiftieth anniversary of the 1972 conference. We are running out of time and urgent action is needed. These challenges are global, and we must meet them with a global response that drives action on the ground.”
Inger Andersen, Executive Director of UNEP, who was on 11 October appointed by UN Secretary-General António Guterres as the Secretary-General of the Stockholm+50 international meeting, said: “We need to urgently work to transform our economies and societies, but our branches will spread only as far as our roots are deep. By remembering Stockholm at 50, we also remember how the world came together to heal the ozone layer in 2013, phase out leaded fuel this year and stop endangered species from going extinct. By convening in Stockholm, we also recommit to human and planetary health, responsibility, prosperity, equality and peace – as we have seen only too clearly in COVID-19.”
COVID-19 deaths at lowest level in nearly a year
Although COVID-19 deaths continue to decline, vaccine inequity persists, the head of the World Health Organization (WHO) said on Wednesday, again calling for greater support for developing countries.
Agency chief Tedros Adhanom Ghebreyesus reported that the death toll from the disease is now at its lowest level in almost a year.
“Deaths are declining in every region except Europe, where several countries are facing fresh waves of cases and deaths. And of course, deaths are highest in the countries and populations with the least access to vaccines.”
Tedros appealed for global cooperation. “Countries that continue to roll out boosters now are effectively preventing other countries from vaccinating their most at-risk populations,” he said.
Missing the mark
As of Wednesday, there were more than 238 million COVID-19 cases worldwide, and more than 4.8 million deaths.
WHO had previously pushed governments to vaccinate 10 per cent of their populations by the end of September, a target which 56 nations missed, most of them in Africa.
Tedros said even more countries are at risk of missing the 40 per cent target to be achieved by the end of the year. Three countries – Burundi, Eritrea and the Democratic People’s Republic of Korea – have yet to start vaccinations.
“About half of the remaining countries are constrained by supply. They have a vaccination programme underway, but don’t have enough supply to accelerate enough to reach the target,” he said.
Tedros urged countries and companies that control global vaccine supply to prioritize distribution to the COVAX solidarity initiative and the African Vaccine Acquisition Trust (AVAT).
Meanwhile, WHO and partners are working with other countries, such as those affected by fragility or conflict, to strengthen technical and logistical capacity for vaccine rollout.
“With aggressive and ambitious action, most of these countries can still reach the 40% target by the end of this year, or be on a clear pathway to reaching it.”
Crisis in Tigray
Tedros also addressed the escalating crisis in northern Ethiopia, where a nearly year-long war in the Tigray region has left up to seven million people in urgent need for food and other assistance.
The conflict has spilled over into neighbouring Afar and Amhara, further increasing needs and complicating response efforts. Aid is not reaching the area “at anywhere close to the levels needed”, he said, and communications, electricity, other basis services remain cut off.
WHO and partners are calling for unfettered access to the affected regions, as the lives of millions of people are at stake, Tedros told journalists.
“People with chronic illnesses are dying due to lack of both food and medicine. Nearly 200,000 children have gone without critical vaccinations,” he said
“When people do not have enough food, they are more susceptible to deadly diseases, as well as the threat of starvation, and that’s what we’re now seeing in Tigray.”
Global health community prescribes climate action for COVID recovery
Ambitious national climate commitments are crucial for States to sustain a healthy, green recovery from the COVID-19 pandemic, according to a new UN health agency report launched on Monday in the lead-up to the COP26 climate change conference in Glasgow, Scotland.
Based on a growing body of research confirming numerous and inseparable links between climate and health, the World Health Organization’s (WHO) COP26 Special Report on Climate Change and Health spells out that transformational action in every sector, from energy, transport and nature to food systems and finance is needed to protect people.
“The COVID-19 pandemic has shone a light on the intimate and delicate links between humans, animals and our environment”, said WHO chief Tedros Adhanom Ghebreyesus. “The same unsustainable choices that are killing our planet are killing people”.
An urgent call
WHO’s report was launched at the same time as an open letter, signed by over two thirds of the global health workforce – 300 organizations representing at least 45 million doctors and health professionals worldwide – calling for national leaders and COP26 country delegations to step up climate action.
“Wherever we deliver care, in our hospitals, clinics and communities around the world, we are already responding to the health harms caused by climate change”, the letter from the health professionals reads.
“We call on the leaders of every country and their representatives at COP26 to avert the impending health catastrophe by limiting global warming to 1.5°C, and to make human health and equity central to all climate change mitigation and adaptation actions”.
Fossil fuels ‘killing us’
Both the report and open letter come as unprecedented extreme weather events and other climate impacts are taking a rising toll on everyone.
Heatwaves, storms and floods have taken thousands of lives and disrupted millions of others while also threatening healthcare systems and facilities when they are needed most, according to WHO.
Changes in weather and climate are threatening food security and driving up food-, water- and vector-borne diseases, such as malaria, while climate impacts are also negatively affecting mental health.
“The burning of fossil fuels is killing us. Climate change is the single biggest health threat facing humanity”, states the WHO report. And while no one is safe from the health impacts of climate change, “they are disproportionately felt by the most vulnerable and disadvantaged”.
Climate actions far outweigh costs
Meanwhile, air pollution, primarily the result of burning fossil fuels, which also drives climate change, causes 13 deaths per minute worldwide, according to WHO.
The report states clearly that the public health benefits from implementing ambitious climate actions far outweigh the costs.
“It has never been clearer that the climate crisis is one of the most urgent health emergencies we all face”, said Maria Neira, WHO Director of Environment, Climate Change and Health.
“Bringing down air pollution…would reduce the total number of global deaths from air pollution by 80 per cent while dramatically reducing the greenhouse gas emissions that fuel climate change”, she pointed out.
Dr. Neira added that a shift to more nutritious, plant-based diets “could reduce global emissions significantly, ensure more resilient food systems, and avoid up to 5.1 million diet-related deaths a year by 2050”.
Call to action
Although achieving the Paris Agreement on climate change would improve air quality, diet and physical activity – saving millions of lives a year – most climate decision-making processes currently do not account for these health co-benefits and their economic valuation.
Tedros underscored WHO’s call for all countries to “commit to decisive action at COP26 to limit global warming to 1.5°C – not just because it’s the right thing to do, but because it’s in our own interests”, and highlighted 10 priorities in the report to safeguard “the health of people and the planet that sustains us.”
