You know you have dry skin when you feel it, you don’t have normal hair placement when you see yourself, or when a pair of shoes begins to alter your gait. Eyes may be duller.Eyes may be more subdued. They tend to gravitate to calling attention to themselves with small nuisances: a little more eye strain at night; the occasional fuzziness that comes and goes; headache when reading; redness that is too common to say much.

Edward C. Wade, M.D., F.A.C.S., from Eye Center of Texas, explains that the better question is simple: Does this feel different from your normal?

Not all of those moments when you’re feeling tired are medical issues. A long day at work, dry air, allergies, wearing contact lenses and excessive screen time can all leave your eyes feeling less than fresh. If, however, changes occur again, they become stronger, or they happen to disrupt your daily routine in any way then it’s best to pay attention to it.

The small changes people tend to explain away

Those who don’t notice their eyes purposefully do so. They simply come up with plausible explanations.

After a long day do you have blurred vision? Probably the screen. Having problems driving at night? Perhaps the headlights are too bright in these days. Can’t see the words to read?Need more light for reading? That’s what old age sounds like. If you experience redness after wearing make up, contacts or are out on an outdoor weekend? It’s convenient to point fingers at the easy-to-understand solution.

At times those explanations are correct. But patterns matter. A symptom which returns, which varies rapidly or which strikes only one eye is worthy of more interest than a hasty shrug.

There are some changes that are particularly easy to normalize. Requires more light for reading or colors are a bit less saturated. For instance, patients might have no symptoms initially with a cataract but develop symptoms later such as blurring or cloudiness in vision or difficulty seeing at night, or double vision, or frequent changes in glasses prescription, or light sensitivity, or halos [1]. But what it does not say is that if you dim something gradually it does not mean that it is a cataract, it also means that.

Also, specks, flashes and shadows are easy to minimize. Some floaters may be normal as a result of healthy ageing. Even if the flurry of floaters subsides, or if they come back in intermittent bursts of light, or if there is a dark shadow that resembles a curtain over the part of the eye, then it may be an indicator of retinal detachment, and it should be treated as an emergency [2].

Then there are the small changes that occur in behavior that do not yet occur in words. You don’t read in bed because it is an annoyance. You refrain from driving at night. You zoom into text on your phone time after time.You zoom in on the text on your phone over and over. You think that you are getting tired but the same things are becoming increasingly difficult. This is when it’s time to ask yourself, “Is this bad enough?” and “Is this new for me?”

Why pain or pressure should not be ignored

It can be difficult to figure out which eye discomfort is serious, and which isn’t. Dryness can burn. Gritty eyes can occur due to an allergy. By the end of the day, contact lenses may cause a heavy, tired feeling.

But pain is different, particularly if it is intense, comes on quickly, is unilateral and associated with other symptoms.

Angle-closure glaucoma (a less common but more sudden kind of glaucoma) may occur with sudden, severe eye pain; red eye, blurred vision or nausea and requires urgent medical attention [3]. It is not the symptom that one should look for after a week, when they’re testing out drops.

Pressure is also complicated, since folks have a variety of definitions for it. Sinus pressure around eyes – some. There are times when some mean a headache. Others experience a fullness or soreness in the eye. A doctor of the eyes can help determine if it is due to the surface of the eye, inflammation, pressure changes, migraine or other causes.

Also be cautious when experiencing pain post eye injury, chemical exposure and recent eye surgery. If the eye appears mostly normal in the mirror, then the eye has become painful following trauma and should be evaluated immediately. After an injury, chemical exposure or recent surgery, it’s better to get some clarity instead of just continuing the testing to see if it helps with the pain.

Take note of the sensation shift in discomfort. If it impacts your conduct, awakens you, alters your viewpoint, is red or light delicate or feels different than you’ve ever noticed previously, it’s worth more than a tired-eye clarification.

How health conditions can show up in your eyes

Eye health is related to the health of other parts of the body. Changes can happen to blood vessels, nerves and even fine tissue in the retina that are not related to vision.

There is none more obvious than diabetes. High blood sugar over time may cause blood vessels in the retina to become damaged and cause blurring of vision and vision loss [4]. Taking steps to control blood pressure and cholesterol can also reduce the risk of eye disease and vision loss among diabetics, according to the CDC [4].

This is why it’s important to have an eye exam even if your prescription looks fine. It’s possible to have a chart that you can see, but still require monitoring for retinal, optic nerve or blood vessel changes.

Regular eye care is important for other reasons, too: glaucoma. The most common form tends to grow gradually and lots of people may not experience symptoms initially. A dilated eye exam is the most thorough eye exam your eye doctor performs to diagnose glaucoma and other eye diseases [3]. A sense of different vision is not a sure sign of a different vision.

Family history is important, too. If family members have glaucoma, macular degeneration, a retinal disease or a medical loss of vision, this should be noted during the examination. This is also true for auto-immune diseases, a history of steroid use, a history of eye surgery and for high myopia.

That’s where it’s not about panic, and it’s about context. No single symptom is as important as the sum of all your symptoms, health history, medications, family history and exam findings.

Making an eye appointment feels less dramatic

Many people avoid getting medical care because they think there is nothing wrong with them or they wasted everyone’s time, or there is something wrong, and they will have to make a big decision right away.

Major eye appointments are not as dramatic as individuals may think.

The appointment could just be about dryness, allergies, change of prescription or a minor irritation. It might discover a condition that requires to be watched but not treated right away. It could provide you with more information on what to look out for, when to drop, when to stop wearing contacts, or when to return.

Even if it’s a bad thing going on, you will have better options if you know about it early on.

The American Academy of Ophthalmology suggests that if you are without symptoms and don’t have any known risk factors, you should get an eye exam by age 40 [5]. Those with symptoms, a higher risk, diabetes, or an existing eye disease might require a different schedule.

It might be helpful to make a list of things that are different before you leave. Record the onset of the symptom, if one eye or both, what aggravates, what helps, if flashes or floaters or pain or redness or headaches or sensitive to light or problems driving at night. Take your glasses and information on your contacts, list of your medications and any health history.

For those in Greater Houston, the practice’s medical and surgical eye care may be beneficial in cases where symptoms are difficult to classify. Sometimes the changes of the lens, cornea, retina, optic nerve or surface of the eye may overlap and can be difficult to identify, unless a comprehensive exam is done.

Disruption doesn’t have to come before a change in vision. Your eyes sometimes tell you to take notice in more subtle ways like: something seems more difficult, something keeps coming back, a visual change that you can’t account for. Being attentive early is not hypervigilant! The subtlety of it is just that it is a method of not allowing little changes to seep into parts of your routine unnoticed.
