As an eye doctor, I often hear: "My eyes feel sore and dry. Is my vision getting worse?" Usually the answer is: not necessarily. Most of the time, the eyes are just working too hard for too long, with fewer blinks and a setup that strains focus.
1. Why eyes get tired so easily
When you look up close, the focusing muscle stays contracted, like holding a fist without letting go. Add fewer blinks during screen use, and the eye surface dries out, leading to soreness and fatigue.
- Close work keeps the focusing muscle tense
- Fewer blinks means less tear coverage
- Poor lighting makes the eyes work harder
2. Three habits you can start today
- 20-20-20: every 20 minutes, look 20 feet away for 20 seconds
- Keep distance: screens about an arm's length away
- Blink on purpose: slow, full blinks keep eyes hydrated
3. Don't over-rely on "eye gadgets"
Special lamps and blue-light glasses are not magic. The basics matter more: soft lighting, a screen that is not too bright, and text that is easy to read without squinting. Habits usually matter more than gear.
4. Can I use eye drops all the time?
Artificial tears can ease dryness, but avoid long-term use of drops with preservatives. If you need drops many times a day, it is worth an exam to check for dry eye.
Sudden vision loss, severe eye pain, flashes, or missing areas of vision should be checked urgently.
5. What foods support eye health?
"Just eat carrots" is a myth. Eyes need a mix of nutrients such as lutein, omega-3s, vitamin A, and zinc. A simple approach: dark leafy greens, eggs, and oily fish, plus consistent sleep.
6. When does an online vision test help?
Online checks are great for quick monitoring: is clarity stable, and are small changes showing up? If blur is persistent or headaches keep happening, you still need a full in-person exam.
