1
The Comprehensive Eye Exam Prescription + eye health + early detection

Good vision does not always mean healthy eyes. The exam checks refraction plus the health of the cornea, lens, retina, and optic nerve.

What a good exam often includes

  • History: symptoms, work habits, medications
  • Refraction: best clarity for glasses/contacts
  • Eye pressure (IOP) + optic nerve evaluation
  • Anterior segment check (dry eye, cornea, cataract signs)
  • Retina screening (diabetes, vascular changes, macular health)

Frequency (simple guide)

  • Kids: at least every 1–2 years, sooner if headaches or school trouble.
  • Adults: every 1–2 years.
  • 40+ / risk factors: yearly is often best.
Bring: your old glasses, contact lens boxes, and any recent medical reports.
2
Contact Lens Care Hygiene • water safety • safe wear schedule

Contacts are medical devices. Clean habits protect your cornea from infections.

Golden rules
  • Wash and dry hands before touching lenses.
  • Never rinse lenses/case with tap water.
  • Never sleep in lenses unless prescribed.
  • Stop wearing lenses if pain/redness increases.
Case routine
  • Empty old solution every time.
  • Rinse case with solution, air-dry face down.
  • Replace case every 1–3 months.

Comfort tips

  • Use rewetting drops that are approved for contacts.
  • Limit wear time on very dry/screen-heavy days.
Urgent: pain + light sensitivity + blurred vision with contacts → remove lens and get checked quickly.
3
Digital Eye Strain (Computer Vision) Dryness • headaches • focusing fatigue

Screen work reduces blink rate and forces constant focusing. This can cause dryness and headaches.

Fast improvements

  • 20-20-20 rule + blink reminders.
  • Screen slightly below eye level, about an arm’s length away.
  • Reduce glare: avoid bright window reflection.

Optical solutions

  • AR coating reduces reflections and improves comfort.
  • Office lenses for heavy computer users (best intermediate vision).
Tip: If you feel “tired eyes” mostly at screens, you may need an updated Rx or a special computer Rx.
4
Dry Eye Basics Burning • sandy feeling • fluctuating vision

Dry eye can feel like burning, grit, tearing, or blurry vision that comes and goes.

At-home support

  • Warm compress 5–10 minutes (if advised).
  • Preservative-free lubricants for frequent use.
  • Limit direct air from AC/car vents.
  • Omega-3 intake may support tear quality (ask your clinician).

When to evaluate

  • If symptoms persist, worsen, or affect contact lens wear.
5
Shortsightedness (Myopia) Outdoor time • screen habits • progression control

Myopia makes distance vision blurry. It often progresses during childhood growth.

Habits that help (especially for children)

  • Outdoor time (daily, as possible).
  • Breaks during near work + 20-20-20 rule.
  • Good lighting and reading distance ~30–40 cm.

Parent checklist

  • Sits very close to TV or books
  • Screens bring headaches
  • Squinting or eye rubbing
Ask us: myopia management options and the best frame size for high myopia cosmetics.
6
Astigmatism Clearer vision with precise toric correction

Astigmatism causes blur and ghosting at all distances because light focuses unevenly.

What helps most

  • Accurate Rx and proper axis alignment.
  • AR coating to reduce night glare and halos.
  • For contacts: toric lens stability and correct fitting.
Tip: If your toric contact lens rotates, your vision may fluctuate — a refit can fix it.
7
Presbyopia (40+) Progressives • office lenses • comfort adaptation

Presbyopia is the normal reduction of near focusing power with age.

Best lens options

  • Progressive lenses (distance + intermediate + near).
  • Office lenses for computer + reading comfort.
  • Readers for occasional near tasks.

Adaptation tips

  • Wear new progressives consistently for the first week.
  • Move your head (not only eyes) when scanning.
  • Return for fitting adjustments if you feel swim or distortion.
8
UV Protection & Sunglasses Protect your eyes outdoors • reduce long-term risk

UV protection helps protect the cornea, lens, and retina over time.

Choose sunglasses with

  • UV400 / 100% UVA-UVB protection.
  • Polarized lenses for glare (driving/sea).
  • Good coverage: wrap or larger shapes reduce side UV.
Tip: Dark lenses without UV protection are not safe — they can make pupils open wider.
9
Choosing Frames That Look Better (Cosmetics) Better comfort • better lens thickness appearance

Frame choice changes how thick lenses look and how comfortable glasses feel.

Simple cosmetic rules

  • Higher prescriptions look best in smaller, round/oval shapes.
  • Thicker acetate frames can hide lens edges better.
  • Centered pupils in the frame improve optics and cosmetics.

Comfort check

  • Bridge fit: no slipping, no red marks.
  • Temple fit: stable, not too tight behind ears.
10
Changing Eye Colour (Cosmetic Lenses) Approved materials only • never share lenses

Cosmetic lenses can be safe only when properly fitted and handled.

Safety checklist

  • Never buy unregulated “costume” lenses.
  • Never share lenses with anyone.
  • No sleeping in colored lenses.
  • Stop immediately if pain/redness occurs.
11
Night Driving & Glare AR coating • clean lenses • check astigmatism

Glare and starbursts at night can come from astigmatism, dirty lenses, scratches, or early lens changes.

What to do

  • Update Rx and confirm astigmatism axis.
  • Use premium AR coating.
  • Keep lenses clean; replace scratched lenses.
  • Ensure windshield is clean inside/out.
12
Kids: Signs Your Child Needs an Eye Exam School performance • squinting • eye rubbing

Children may not complain. Watch for behaviors that suggest vision issues.

Common signs

  • Sits too close to TV / holds devices very close
  • Squinting, head tilt, closing one eye
  • Frequent headaches after school
  • Skipping lines while reading
  • Eye rubbing or light sensitivity
Tip: Early correction prevents learning struggles and improves confidence.
13
Lens Coatings Explained AR • hydrophobic • scratch resistance • UV

Good coatings improve clarity, comfort, and lens life.

Most useful coatings

  • Anti-reflective (AR): sharper vision, less glare, better night driving.
  • Hydrophobic/oleophobic: easier cleaning, less smudging.
  • Hard coat: improves scratch resistance.
  • UV protection: extra safety outdoors (especially important for kids).
Tip: Premium AR is worth it if you use screens often or drive at night.
14
When to Update Your Prescription Blur • headaches • posture changes

Don’t wait until the lens is “unusable.” Updating early improves comfort and productivity.

Common reasons to update

  • New headaches, eye fatigue, blurred distance or near
  • Difficulty switching focus (screen ↔ far)
  • Stronger glare at night
  • New reading posture (holding phone farther away)
