👁️ Amblyopia

Vision is reduced (even with glasses) because the optic nerve has not fully developed.

Prevention: If you were prescribed glasses, wear them until at least age 14 to ensure full development.

🌙 Astigmatism

An irregular curvature of the cornea that causes blurry vision.

👓 Bifocal Glasses

Lenses with two prescriptions: the top is for distance and the bottom is for near.

Not ideal for computer use because they do not provide intermediate vision. Bifocals also have visible lines.

🌫️ Cataract

The natural lens becomes cloudy, causing blurry vision even with new glasses.

Prevention: UV light contributes to cataracts. Wear sunglasses with 100% UV protection.

👁️‍🗨️ Conjunctivitis

Infection and/or inflammation of the conjunctiva (the thin tissue covering the white part of the eye).

🔍 Farsightedness (Hyperopia)

Distance vision is clearer while near vision is blurry. Caused by an eyeball that is too short.

🫧 Floater

A particle floating in the vitreous. Seen as a black/gray spot or wiggly line that moves with your eye.

🧠 Glaucoma

An eye disease affecting the optic nerve, causing loss of peripheral (side) vision.

🌀 Keratoconus

Thinning and distortion of the cornea, causing blurry vision even with glasses or soft contacts.

Often requires rigid gas permeable contacts. Severe cases may require a corneal transplant.

🎯 Macular Degeneration

A disease affecting the macula that causes loss of central vision.

Prevention: Take vitamins with lutein, meso-zeaxanthin, zeaxanthin, and omega-3. Wear sunglasses, use blue-blocking lenses, and avoid smoking.

👁️ Monovision

One eye is corrected for distance and the other eye is corrected for near (contacts or laser surgery).

📍 Myopia (Nearsightedness)

Near vision is clear, but distance vision is blurry. Caused by an eyeball that is too long.

🔄 Nystagmus

Rapid, uncontrollable eye movements. Vision is often poor even with glasses, usually due to macular disease.

🌍 Peripheral Vision

Side vision.

📖 Presbyopia

Near vision becomes blurry because the focusing muscle is no longer pulling enough on the lens.

✨ Progressive Glasses

Lenses that allow vision at all distances: top for far, middle for intermediate, bottom for near.

Unlike bifocals or trifocals, progressives have no visible lines.

🌬️ Pterygium

Tissue growth over the cornea caused by UV exposure, wind, dust, or chemicals.

🩸 Retinopathy

Retinal disease that can lead to blindness, often caused by diabetes or high blood pressure.

Prevention: Control diabetes and high blood pressure.

👀 Strabismus

Also known as crossed eye or lazy eye. One eye turns inward or outward.

🌤️ Transitions Lenses

Lenses that darken when exposed to UV light. Clear indoors, darker outdoors.

They may not get very dark inside a car because windshields block UV rays.

🔎 Trifocal Glasses

Lenses with three prescriptions: distance (top), intermediate (middle), and near (bottom).

Trifocals have visible lines and are less aesthetic than progressives.
