Now I have enough information to give a thorough, clinically accurate answer. Let me synthesize this.

Olopatadine for Eye Redness and Dryness from Sleep Deprivation - Is It Appropriate?

Short answer: No, olopatadine is not the right treatment here.

Why Olopatadine Is Not Indicated

Olopatadine (brand names Pataday, Patanol) is a topical H1 antihistamine with mast cell-stabilizing properties. Its approved indication is allergic conjunctivitis - itchy, red, watery eyes triggered by allergens (pollen, dust mites, pet dander, etc.).

Goodman & Gilman's describes it as "a topical H1 antagonist with additional mast cell-stabilizing and anti-inflammatory properties... an effective treatment of allergic conjunctivitis."
Wills Eye Manual lists it under treatment of allergic and vernal/atopic conjunctivitis.

Redness and dryness from 48 hours without sleep is a completely different mechanism:

Sleep deprivation reduces blink rate and tear production, causing ocular surface desiccation
There is no allergen, no histamine release, no mast cell degranulation driving the symptoms
Olopatadine will do nothing meaningful for this type of redness or dryness

What Actually Causes This

After sleep deprivation, the eyes are red and dry because:

Reduced blink frequency - leads to tear film instability and evaporative dry eye
Decreased nocturnal tear replenishment - eyes normally rest and recover tear film during sleep
Conjunctival vasodilation - from fatigue and prolonged exposure

What Actually Helps

From Wills Eye Manual and Rosen's Emergency Medicine:

Symptom	Treatment
Dryness / Foreign body sensation	Preservative-free artificial tears (lubricant drops) - use frequently, e.g. 4-8x/day
Redness from dryness	Artificial tears address the root cause; avoid vasoconstrictors (naphazoline, tetrahydrozoline - "Visine"-type drops) due to rebound redness with repeated use
Mild irritation	Cool compresses several times per day

The definitive treatment is sleep. Symptoms will resolve on their own once normal sleep resumes.

Cautions

Avoid decongestant/vasoconstrictor eye drops (naphazoline, tetrahydrozoline) for repeated use - they cause rebound redness (rebound hyperemia) when used frequently
Avoid olopatadine here - it won't help and is unnecessary antihistamine exposure
If redness and dryness persist well beyond catching up on sleep, consider evaluation for underlying dry eye disease or other causes of chronic red eye (uveitis, keratitis, glaucoma)

Bottom line: Use preservative-free artificial tears for symptom relief, apply cool compresses, and sleep. Olopatadine is not appropriate for sleep deprivation-related eye symptoms as there is no allergic/histamine-driven component to treat.

Can sleep deprivation cause permanent eye damage or corneal scarring?

Here is a clear breakdown of what the evidence actually says:

Can Sleep Deprivation Cause Permanent Eye Damage or Corneal Scarring?

Short-term deprivation (1-3 nights): No permanent damage

For the scenario you described - 2 days without sleep - permanent eye damage does not occur. The effects are entirely reversible. Adams and Victor's Principles of Neurology (12th ed.) documents that sleep deprivation produces neurologic eye signs including:

Impairment of saccadic eye movements
Loss of accommodation
Exophoria (outward eye deviation)
Ptosis of the eyelids
Mild and inconstant nystagmus

All of these resolve with recovery sleep. Corneal scarring from 48 hours of wakefulness alone is not documented in the medical literature.

How corneal damage actually occurs (for context)

Corneal scarring requires a different, more severe mechanism. It develops from:

Exposure keratopathy - incomplete eyelid closure (lagophthalmos) that allows the cornea to dry out and become ulcerated, progressing to scarring if untreated. This happens with facial nerve palsy, thyroid eye disease, or surgical complications - not from sleeplessness. Kanski's Clinical Ophthalmology states: "Exposure keratopathy is the result of incomplete lid closure (lagophthalmos), with drying of the cornea despite normal tear production."
Chronic untreated dry eye disease - with persistent ocular surface inflammation, chronic damage can occur over months to years, not days.
Corneal infection/ulceration - typically from bacteria, herpes, or contact lens misuse.

Simply being awake for 2 days does not cause lagophthalmos, and your blink reflex remains active throughout wakefulness, providing continuous corneal protection.

Chronic, long-term sleep deprivation: Indirect risks exist

This is different from acute sleep loss. Weeks to months of poor sleep are associated with:

Condition	Mechanism
Progressive dry eye disease	Repeated failure to replenish tear film nightly leads to tear film instability and chronic ocular surface inflammation
Glaucoma risk	Obstructive sleep apnea is a recognized risk factor for glaucoma (via intermittent hypoxia affecting the optic nerve); population studies show people sleeping <3 hours had 3x higher rates of optic nerve damage
Worsening diabetic retinopathy	Poor sleep worsens glycemic control, which can accelerate retinal vascular damage in diabetics

Bottom line for your situation

Two nights without sleep will cause red, dry, irritated eyes - but no permanent damage. Once you sleep, the eyes recover. Continued use of artificial tears in the meantime prevents the minor dry-eye irritation from becoming uncomfortable. The only real risk from isolated, acute sleep deprivation is the increased accident risk from impaired judgment and reaction time - not eye injury from the sleeplessness itself.
