You've perfected your skincare regimen, meticulously curated your hair care routine, and optimized your supplement stack for peak performance.

But when it comes to safeguarding your eye health, many people are simply winging it without much thought or strategy.

It's perplexing how individuals who religiously apply sunscreen and never sleep with makeup on still engage in eye-damaging behaviors like vigorously rubbing their eyes, fixating on digital screens for extended periods without adequate blinking, and dismissing symptoms as mere fatigue. In the meantime, eye specialists are observing a surge in conditions that traditionally appeared in later years, now emerging as common concerns in routine examinations.

Dr. Julie Chung, an accomplished eye surgeon at UCLA and co-founder of T3, encounters these issues daily. Positioned at the crossroads of medical health and aesthetic beauty, she possesses deep insights into the scientific mechanisms at play, as well as the commonplace lifestyle choices that contribute to them.

In the following sections, she outlines the most prevalent daily habits she observes in her practice and provides practical alternatives to protect your vision.

1. Prolonged Screen Staring Throughout the Day

Back when I first entered the medical field, dry eye syndrome was primarily a concern for patients in their 50s or beyond, or those dealing with specific underlying health issues. Today, however, it has reached epidemic proportions, with digital screens being the primary offender. Fixating on a screen drastically reduces your blink rate, resulting in evaporative dry eye as tears evaporate too quickly. My straightforward recommendation is to blink intentionally and frequently—what I refer to as "blink breaks." Every 15 to 30 minutes, pause what you're doing, blink several times deliberately, and shift your gaze to a distant object. Supplement with preservative-free artificial tears if your eyes feel particularly uncomfortable or dry.

2. Inadequate Removal of Eye Makeup

Failing to thoroughly cleanse eye makeup not only contributes to dry eye but can lead to far more serious complications. Residue from makeup that lingers at the base of your eyelashes clogs the meibomian glands, which are responsible for producing the essential oil layer in your tear film that prevents rapid evaporation. Without this protective oil, your tear film destabilizes, paving the way for chronic dryness and irritation.

Patients often react with surprise when I inquire about recent glittery eye makeup during an exam, even as they insist they've removed it all. Under microscopic examination, every speck is visible. Make it a non-negotiable nightly ritual to remove all eye makeup completely, ideally using a gentle micellar water cleanser that effectively dissolves products without harsh rubbing.

Additionally, accumulated makeup residue creates an ideal environment for demodex mites to proliferate excessively along your lash line. While a small population of these mites is normal for everyone, inconsistent cleansing allows them to multiply unchecked, exacerbating inflammation and discomfort.

3. Forgetting to Wear Sunglasses

Prolonged exposure to ultraviolet (UV) rays accelerates the development of cataracts and pterygiums—those invasive, fleshy growths that gradually encroach onto the surface of your cornea. Protecting your eyes is straightforward: always wear high-quality sunglasses with UV protection. This is especially crucial if you reside in a region with intense sunlight, such as Southern California, where cumulative damage adds up quickly over time.

4. Opting for Semi-Permanent Lash Extensions

Let's be direct: semi-permanent lash extensions are inherently problematic, regardless of the salon’s reputation or the amount invested. It's impossible to maintain proper hygiene along your lash line while they're in place. The debris and buildup I observe under the microscope is alarming, and I only wish I could capture images to illustrate the issue to every patient. Demodex mites particularly flourish in this environment as well.

Beyond hygiene concerns, these extensions promote dry eye symptoms and, over prolonged use, the added weight and adhesive can compromise the strength of your lash follicles, potentially leading to permanent lash loss. A safer alternative is daily temporary lashes, though even these should be used sparingly to avoid cumulative weakening of the follicles.

5. Contact Lens Misuse, Including Sleeping in Them

Dozing off while wearing contact lenses creates microscopic scratches on the cornea's surface. These tiny injuries serve as gateways for bacterial invasion, which can escalate into severe infections potentially necessitating a corneal transplant. Treat this risk with the utmost seriousness—always remove your lenses before bed.

Exposing contacts to water environments like swimming pools or hot tubs introduces an even graver threat from Acanthamoeba, a parasitic organism that breeds in such settings. The infections it causes are notoriously difficult to treat and can result in profound vision loss. Furthermore, avoid the dangerous habit of rinsing or "rewetting" lenses with tap water or saliva, as I've witnessed the devastating outcomes firsthand. Opt for daily disposable lenses whenever possible; they dramatically lower your overall infection risk by eliminating the need for storage and cleaning.

6. Applying Lash Growth Serums Without Awareness of Potential Side Effects

Products like Latisse and other prostaglandin analog serums for lash enhancement have skyrocketed in popularity, and it's easy to see the appeal for longer, fuller lashes. However, many users are unaware of the significant side effects that warrant full disclosure. These include darkening of the skin around the eyes (hyperpigmentation), permanent shifts in iris color toward brown, localized inflammation, and the most insidious risk: periorbital fat atrophy. This gradual loss of fat padding around the eye socket unfolds silently over years, culminating in a gaunt, hollowed appearance that's challenging to reverse once evident.

Under no circumstances should children or teenagers use these serums. For adults considering them, here's advice from my dual perspective as a physician and occasional user: application frequency can be minimized to once weekly—or even every other week—to achieve noticeable results. Embracing a "less is more" philosophy truly benefits your long-term eye health.
