Dr. Douglas Lazzaro, an ophthalmology professor at NYU Langone Health, warns that common habits such as failing to protect eyes from sunlight, reading in poor lighting conditions, eating unhealthy diets, not staying hydrated, and getting insufficient sleep could accelerate age-related eye diseases like cataracts and macular degeneration. For instance, prolonged sun exposure without proper protection can lead to earlier onset of cataracts by five to ten years compared to three decades ago. Lazzaro advises using sunglasses in bright conditions and increasing indoor lighting when reading, among other preventative measures.

As Americans live longer, experts say everyday habits may be taking a toll on eye health earlier than expected.
uncertain
habits → live → health
Dr. Douglas Lazzaro, professor of ophthalmology at NYU Langone Health, warned that several everyday habits may be silently affecting eye health.
uncertain
habits → warn → health
Age-related eye conditions include glaucoma, which damages the optic nerve, and cataracts, a clouding of the eye’s lens that can block light and blur vision.
asserted
that → relate → vision
While genetics and aging remain major drivers of many eye diseases, avoiding the following common mistakes may help slow their progression and protect vision, Lazzaro told Fox News Digital.
uncertain
Lazzaro → remain → Digital
No. 1: Not protecting eyes from the sun
While exposure to sunlight is beneficial for overall metabolic health and longevity, failing to protect the eyes from the sun may lead to accelerated damage.
uncertain
failing → protect → damage
Lazzaro pointed to research suggesting that long-term ultraviolet exposure may contribute to macular degeneration and the progression of cataracts.
uncertain
exposure → point → cataracts
In the doctor's own practice, cataracts are appearing five to 10 years earlier than they did three decades ago, which he believes may be linked to ultraviolet light exposure.
uncertain
he → appear → exposure
He recommends wearing sunglasses in bright, sunny conditions to help protect the eyes, including the lens and retina.
asserted
He → recommend → lens
No. 2: Reading in poor light
Reading in poor lighting can increase eye strain and make it harder to focus, particularly with age, according to Lazzaro.
uncertain
it → read → Lazzaro
"As we get older, our eyes have more difficulty seeing under certain lighting conditions," he told Fox News Digital, noting that older adults may have more difficulty adjusting to darker environments.
"If you're going be reading and it's not a bright, sunny day outside or you're not inside with bright lights, you should increase the lighting," he recommended.
uncertain
he → get → lighting
No. 3: Not eating a healthy diet
Research suggests that a nutritious diet may protect eye health by reducing the risk of diabetes and cardiovascular disease, both of which can affect vision.
uncertain
both → eat → vision
"Diet is important," Lazzaro said.
asserted
Lazzaro → say → ?
"There's certainly a lot of known data about poor diets [contributing] to poor cardiovascular health, and that same thing can apply with the eye."
High cholesterol and high blood pressure can worsen diabetic eye disease, even when patients may not realize those conditions are affecting their vision, according to the doctor.
uncertain
conditions → be → doctor
Researchers are also exploring whether gut health may influence retinal health, although that connection is still emerging.
uncertain
connection → explore → health
No. 4: Not staying hydrated
Another condition that becomes increasingly common with age is dry eye, in which a lack of tear production and oil secretion causes red, itchy, irritated eyes.
asserted
lack → stay → eyes
This condition can be exacerbated by lifestyle factors like dehydration, Lazzaro noted.
asserted
Lazzaro → exacerbate → dehydration
Staying hydrated helps keep the cornea properly moisturized, he said.
asserted
he → stay → cornea
"We always tell our patients, particularly in the summer, if they're going out on a hot day … make sure to hydrate, because not only will it dry out the body … but it can dry out your corneas.
asserted
it → tell → corneas
"
No. 5: Getting poor sleep
Getting adequate sleep helps support overall health, and there’s "good evidence" that patients who don’t sleep well, particularly those with sleep apnea, may experience increased eye pressure, according to Lazzaro.
uncertain
who → get → Lazzaro
People with sleep apnea also appear to face higher rates of glaucoma and certain vascular eye conditions, similar to their increased cardiovascular risk, the doctor said.
asserted
doctor → appear → risk
"They also have an increased incidence of vascular phenomena in the eye …
asserted
They → have → eye
People who don't sleep well have fluctuations in their circulation at night."
No. 6: Rubbing the eyes
Eye rubbing is considered a risk factor for keratoconus, a progressive eye disease where the cornea begins to dome and bulge out in a cone shape, although experts' opinions differ on whether it can directly cause the disease, according to Lazzaro.
Patients with keratoconus often rub their eyes frequently, he noted, and repeated rubbing can potentially change the shape of the cornea — one reason he "strongly" advises against the habit.
uncertain
he → sleep → habit
No. 7: Delaying routine eye doctor visits
Because glaucoma often develops without symptoms, a comprehensive eye exam is frequently the only way to detect it early, Lazzaro said.
asserted
Lazzaro → delay → it
Glaucoma is known as a "silent disease" that can lead to blindness, the doctor noted.
asserted
doctor → know → blindness
"Its nickname is 'the silent thief of sight,'" he said.
asserted
he → say → sight
"Sometimes the only way you know you have glaucoma is by going to the ophthalmologist.
asserted
you → know → ophthalmologist
It’s a disease that we see with increasing frequency as we get older."
asserted
we → ’ → frequency
Lazzaro recommends that adults get annual eye exams, rather than waiting until age-related vision changes begin.
asserted
changes → recommend → exams
Presbyopia — the gradual loss of the ability to focus on nearby objects — commonly develops in middle age and often leads to the need for reading glasses.
asserted
Presbyopia → focus → glasses
"The only way you know you have glaucoma is by going to the ophthalmologist."
asserted
you → know → ophthalmologist
"Patients will come in at some point, usually between 40 and 50, and say they can't see up-close anymore; it happened overnight," he said.
asserted
he → come → 40
Annual visits should also include a scan for skin cancer and eyelid tumors, which occur more frequently with age, the doctor advised.
asserted
doctor → include → age
Sun exposure may contribute not only to cataracts and macular degeneration, but also to cancers of the eyelid, Lazzaro said.
uncertain
Lazzaro → contribute → eyelid
"Most of them can be removed locally without a big problem if diagnosed early," he added.
asserted
he → remove → problem
