Eye Conditions

This page provides basic education for EyeCare users. It does not replace diagnosis, examination, treatment, or follow-up advice from an ophthalmologist.

When to Seek Care

Do not rely on screen-care software alone if any of the following occurs:

• New floaters or a sudden increase in floaters
• Flashes of light, camera-flash-like symptoms, or lightning-like streaks
• A dark shadow, curtain, or blocked area in the visual field
• Sudden vision loss, obvious distortion, or a central dark spot
• Eye pain, redness, trauma, or abnormal vision after injury
• New symptoms after diabetes, high myopia, or eye surgery

These symptoms may relate to retinal tears, retinal detachment, intraocular inflammation, bleeding, or other problems that need professional examination.

Central Serous Chorioretinopathy

Central serous chorioretinopathy is often shortened to CSC or CSCR. It usually involves fluid buildup near the macula, causing blurred, dim, distorted, or smaller-looking central vision. It is more common in young and middle-aged adults.

Common symptoms:

• Blurred central vision in one eye
• Straight lines looking bent
• Objects appearing smaller or dimmer
• Reading and face recognition becoming harder
• Mild symptoms that may still require OCT to detect

Screen-use suggestions:

• Reduce long continuous high-intensity screen sessions
• Keep regular rest and sleep rhythms
• Avoid self-directed steroid use; if already using steroid medication, consult the prescribing doctor before changing it
• Follow the ophthalmologist's OCT review plan

The EyeCare rehabilitation-assist scene is suitable for gentle reminders: short breaks, lower glare, no forced eye exercise, and no aggressive lock screen behavior.

Floaters and Flashes

Floaters are small dots, lines, rings, or web-like shadows that drift in the visual field. Many long-term stable floaters are related to vitreous aging and may gradually become less noticeable, but new or suddenly increased floaters need attention.

Common symptoms:

• More obvious against white walls, sky, or bright screens
• Dots or lines that move with eye movement
• Possible flashes of light

Screen-use suggestions:

• Stable floaters without vision change can be followed by regular eye checks
• First-time, sudden, increased, or flash-accompanied floaters should receive a dilated fundus exam promptly
• Avoid repeatedly staring at floaters to locate them; it can increase anxiety and attention load
• Lower excessive screen brightness and use softer themes when reading bright backgrounds

Cataracts

Cataracts are clouding of the lens. They are common with aging and can also relate to diabetes, trauma, ultraviolet exposure, or steroid use. Early discomfort may be reduced by better lighting and proper glasses; daily-life impairment usually needs surgical evaluation.

Common symptoms:

• Blurred or foggy vision
• Poor night vision
• Strong glare sensitivity
• Faded colors
• Halos around lights
• Frequent changes in glasses prescription

Screen-use suggestions:

• Use more even environmental light that is bright but not harsh
• Avoid large brightness gaps between screen and surrounding environment
• Use sunglasses and brimmed hats outdoors when appropriate
• Use larger text, bold fonts, or higher contrast for reading
• Consult an ophthalmologist when reading, driving, or daily life is affected

A screenbar may improve desk lighting, but it cannot treat cataracts.

Dry Eye and Visual Fatigue

Long screen sessions reduce blinking and can lead to dryness, soreness, foreign-body sensation, and visual fatigue. This does not always mean severe eye disease, but untreated symptoms can affect work comfort.

Screen-use suggestions:

• Use 20-20-20 or more frequent break rhythms
• Blink fully and intentionally
• Reduce overly bright screens and avoid direct air-conditioning airflow
• Ask a doctor whether artificial tears are suitable when needed

High Myopia

People with high myopia have higher risk of retinal tears, retinal detachment, and other fundus problems. New floaters, flashes, or field shadows should be checked more actively than in the general population.

Screen-use suggestions:

• Keep regular dilated fundus examinations
• Avoid high-impact sports when advised by a doctor
• Do not simply attribute vision changes to "eye strain"
• Keep stable rest and lighting habits, and reduce long near-work sessions

What EyeCare Can Do

EyeCare is suitable as a daily screen-use management tool:

• Timed rest reminders
• Lower screen stimulation and glare
• Habit and usage records
• Rehabilitation-assist scene
• Desk-lighting improvement when paired with a screenbar

EyeCare cannot:

• Diagnose disease
• Replace OCT, dilated fundus exam, slit-lamp exam, or other medical tests
• Treat CSCR, cataracts, retinal tears, retinal detachment, or similar diseases
• Replace medication, surgery, or follow-up plans from a doctor

Suggested Scenes

Situation	Suggested setting
CSCR recovery or post-treatment recovery	Rehabilitation Assist: 25-minute work + 60-second rest, gentle filter
Stable floaters with anxiety	Reading or Rehabilitation Assist; avoid long high-brightness white backgrounds
Early cataract with glare sensitivity	Gentle filter + screenbar, with even ambient light
Dry eye and visual fatigue	20-20-20 or Pomodoro, with blink and rest reminders
High myopia	Regular breaks; seek care promptly for new floaters, flashes, or visual-field shadows
