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

But what about your eye health? It's likely being neglected amid the daily hustle.

Interestingly, individuals who religiously apply sunscreen and never sleep with makeup on are often the ones caught rubbing their eyes vigorously, 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 emerged later in life, now presenting as common everyday concerns among younger patients.

Dr. Julie Chung, an accomplished eye surgeon at UCLA and co-founder of T3, encounters these issues firsthand. Operating at the crossroads of health and aesthetics, she possesses deep insight into the scientific mechanisms at play, as well as the practical, everyday behaviors that contribute to them.

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

1. Prolonged Screen Staring Throughout the Day

Back when I began my medical career, dry eye syndrome was primarily a concern for patients in their 50s or beyond, or those managing 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. I refer to these 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.

2. Inadequate Removal of Eye Makeup

Failing to thoroughly cleanse eye makeup not only exacerbates dry eye but can lead to more severe complications. Residue from makeup that lingers at the base of your eyelashes clogs the meibomian glands, which are responsible for producing the essential oils that stabilize your tear film. Without sufficient oil, the tear film destabilizes, directly causing dry eye symptoms.

Patients often react with surprise when I inquire about their recent use of glittery makeup—such as from a weekend event—even if they insist they've removed it all. Under microscopic examination, every bit of residue is visible. Make it a non-negotiable nightly ritual to remove all eye makeup completely, ideally using micellar water for gentle yet effective cleansing.

Additionally, accumulated makeup debris creates an ideal environment for demodex mites to proliferate excessively along your lash line. While a small population of demodex is normal for everyone, inconsistent makeup removal allows these mites to multiply unchecked, leading to further irritation and health issues.

3. Neglecting Sunglasses in Outdoor Settings

Prolonged exposure to ultraviolet (UV) rays significantly increases the risk of developing cataracts and pterygiums—fleshy growths that gradually encroach onto the cornea's surface. Protecting your eyes is straightforward: always wear sunglasses, particularly if you reside in a high-UV area like Southern California. This simple step offers substantial long-term benefits for ocular health.

4. Relying on Semi-Permanent Lash Extensions

To be direct, semi-permanent lash extensions pose significant hygiene challenges, regardless of the salon quality or investment involved. It's impossible to maintain proper cleanliness along the lash line with extensions in place. The buildup I observe under the microscope is alarming, and I frequently wish I could document it visually for every patient in my clinic. Demodex mites particularly flourish in this environment as well.

Beyond hygiene, these extensions aggravate dry eye symptoms. Over time, the added weight and adhesive can compromise the strength of your natural lash follicles, potentially resulting in permanent lash loss. Opt for daily disposable temporary lashes as a safer alternative, though even these should be used sparingly to avoid cumulative weakening of the follicles.

5. Contact Lens Misuse, Including Overnight Wear

Sleeping with contact lenses creates microscopic abrasions on the cornea's surface. These small injuries serve as gateways for bacterial invasion, which can escalate into serious infections potentially necessitating a corneal transplant. Treat this risk with the utmost seriousness to avoid irreversible damage.

Engaging in water-related activities like swimming or lounging in hot tubs while wearing contacts introduces an even graver threat from Acanthamoeba, a parasitic organism that proliferates in such environments. The infections it causes can be profoundly destructive and challenging to treat. Furthermore, avoid the dangerous habit of rewetting lenses with tap water or saliva—I have witnessed the devastating outcomes and strongly advise against it. Daily disposable contacts represent the safest choice overall, dramatically lowering your risk of infection.

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

Products like Latisse and other prostaglandin analog serums for lash enhancement have surged in popularity, and their appeal is understandable. However, many users remain uninformed about critical side effects that warrant full disclosure. These include hyperpigmentation around the eyes, permanent shifts in iris color toward brown, localized inflammation, and—most alarmingly—periorbital fat atrophy. The fat loss occurs gradually over years, culminating in a hollowed, sunken appearance around the eyes that becomes evident only after prolonged use.

Under no circumstances should children or teenagers use these serums. For adults considering them, drawing from my dual perspective as a physician and occasional user, the key is moderation: applying it just once a week—or even every other week—can still yield noticeable results. Embracing the principle of 'less is more' will preserve your eye health in the long run. Your eyes will undoubtedly benefit from this cautious approach.
