Daily Habits for Lifelong Eye Health

1
Get an Annual Eye Exam

Most serious eye conditions develop without any early symptoms. An annual exam lets Dr. Mordue catch glaucoma, macular degeneration, diabetic eye disease, and retinal changes before you notice anything is wrong. Early detection is everything.

2
Wear UV-Blocking Sunglasses

Hawaii's sun is intense year-round. UV exposure accumulates over a lifetime and is a leading cause of cataracts and macular degeneration. Polarized, UV400 lenses protect both your eyes and the delicate skin around them.

3
Eat for Your Eyes

Dark leafy greens (spinach, kale), omega-3 rich fish, and foods high in vitamins C and E directly support retinal health. Lutein and zeaxanthin — found in eggs and greens — are particularly protective against macular degeneration.

4
Follow the 20-20-20 Rule

For every 20 minutes of screen time, look at something 20 feet away for 20 seconds. This simple habit dramatically reduces digital eye strain and gives your focusing muscles a needed break.

5
Stay Well Hydrated

Your tear film is mostly water. Even mild dehydration reduces tear production and worsens dry eye symptoms. Aim for 8 glasses a day — more if you're active or spending time outdoors in the Hawaii heat.

6
Never Sleep in Contact Lenses

Sleeping in contacts cuts oxygen to the cornea and multiplies infection risk by 6–8x. Even “extended wear” lenses should be removed whenever possible. If you fell asleep in them, remove them as soon as you wake up.

For Screen Users

Digital Eye Strain Is Real — and Common

If you spend hours a day at a computer, tablet, or phone, you may already know the symptoms: tired eyes, headaches, blurry vision, and a stiff neck. What you might not know is why it happens and how easily it's fixed.


When we stare at screens, we blink up to 60% less than normal. This dramatically reduces the tear film that keeps our eyes moist and clear. Combined with the fixed focus distance of a screen and often poor lighting conditions, the result is a cascade of discomfort that affects more than 65% of American adults.

Quick Fixes That Work

  • Follow the 20-20-20 rule
  • Position your screen 20–24 inches away, slightly below eye level
  • Use the Night Shift or blue light filter on your devices after sunset
  • Blink consciously — remind yourself to blink fully and often
  • Use preservative-free artificial tears during long work sessions
  • See Dr. Mordue to rule out an uncorrected prescription
For Contact Lens Wearers

The Rules Worth Following

Do's
  • Wash and dry your hands before handling lenses
  • Replace lenses on the schedule prescribed (daily, bi-weekly, or monthly)
  • Use fresh solution every day — never top off old solution
  • Store lenses in a clean case with fresh solution when not wearing
  • Remove lenses before swimming, showering, or sleeping
Don'ts
  • Sleep in lenses unless your doctor has specifically approved it
  • Share lenses with anyone
  • Use tap water, saliva, or anything other than contact solution
  • Wear lenses past their expiration date
  • Ignore redness, pain, or blurred vision — remove lenses immediately and call us
