Our eyes work hard from the moment we wake up until the moment we go to sleep. They help us take in information, connect with others, and navigate the world. Despite how important they are, most of us rarely think about how our daily routines might be putting them at risk. Some habits that seem harmless can, over time, lead to discomfort, strain, or even long-term vision problems.
The good news is that a few simple changes can go a long way in protecting your eyes. By understanding which everyday behaviours may be harmful, you can take steps to keep your vision clear and healthy for years to come.
How Does Too Much Screen Time Affect Your Eyes?
Many people spend hours each day looking at phones, computers, and tablets. While screens have become part of our daily lives, they can take a toll on our eyes. Prolonged screen use can lead to a condition known as digital eye strain. Symptoms may include dryness, blurred vision, headaches, and difficulty focusing.
When we focus on a screen for a long time, we tend to blink less often. Blinking keeps the surface of the eye moist and helps protect it from irritation. Less blinking means the eyes can become dry and uncomfortable. Blue light from screens may also disrupt sleep patterns, making it harder to get a restful night.
The easiest way to prevent strain is to follow the 20-20-20 rule. Every 20 minutes, take a break and look at something at least 20 feet away for 20 seconds. Adjusting the brightness of your screen, keeping it at arm’s length, and using artificial tears when needed can also help relieve discomfort.
Why Is Sleeping In Contact Lenses Risky?
Contact lenses are a safe and effective way to correct vision when used properly. However, sleeping in lenses that are not designed for overnight wear increases the risk of serious eye infections. This is because wearing lenses while you sleep reduces the amount of oxygen
reaching the cornea, the clear front surface of the eye.
When the cornea does not get enough oxygen, it becomes more vulnerable to bacteria, fungi, and other harmful microorganisms. Even a short nap in contact lenses can raise the risk of infection. In severe cases, these infections can lead to corneal ulcers, which may cause permanent vision loss if not treated quickly.
To protect your eyes, always remove contact lenses before sleeping unless your optometrist has prescribed extended-wear lenses. Keep your lenses clean, follow replacement schedules, and never wear them longer than recommended.
Why Should You Avoid Rubbing Your Eyes?
It can feel satisfying to rub your eyes when they are itchy or tired, but this habit can cause more harm than good. Rubbing can transfer dirt, debris, and bacteria from your hands to your eyes, increasing the risk of irritation or infection. The skin around the eyes is delicate, and repeated rubbing can cause broken blood vessels or dark circles over time.
For people with certain conditions, such as keratoconus, rubbing the eyes can make the condition worse by changing the shape of the cornea. If your eyes feel itchy, it is better to use lubricating eye drops or a clean, cool compress to relieve discomfort. For persistent itching, see your optometrist to identify and treat the underlying cause.
What Happens When You Skip Sunglasses?
Sunglasses are not just a fashion accessory. They play a critical role in protecting your eyes from ultraviolet rays, which can cause long-term damage. Extended UV exposure increases the risk of cataracts, macular degeneration, and growths on the eye called pterygia. Even on cloudy days, UV rays can penetrate the atmosphere and reach your eyes.
Choosing sunglasses with 100 percent UVA and UVB protection is the best way to guard against this damage. Wraparound styles can offer extra protection by blocking light from the sides. Wearing a wide-brimmed hat can provide additional shade for your eyes. By making sunglasses a daily habit, you reduce your risk of serious eye conditions later in life.
What Other Daily Habits Can Harm Your Eyes?
Some habits may not seem harmful at first but can have long-term effects on your vision.
- Ignoring Regular Eye Exams: Many serious eye diseases, like glaucoma and diabetic retinopathy, develop without symptoms in the early stages. By the time vision changes are noticeable, damage may already be permanent. Annual eye exams allow your optometrist to detect these issues early and begin treatment before they cause lasting harm.
- Using Outdated Makeup Or Not Removing It Properly: Eye makeup can collect bacteria over time. Using old products or failing to clean your eyelids thoroughly before bed can lead to eye infections and irritation. Always replace mascara and liquid eyeliner every three months and wash your face completely before sleeping.
How Can You Protect Your Eyes Every Day?
Simple daily choices can have a lasting impact on your eye health.
- Eat a balanced diet rich in fruits, vegetables, and omega-3 fatty acids to support healthy vision.
- Stay hydrated to keep your eyes moist and comfortable.
- Take breaks during long tasks that require intense focus, such as reading or working on a computer.
- Use proper lighting to avoid unnecessary strain.
- Wear protective eyewear for home improvement projects or activities where debris could enter the eyes.
