ROHTO Cool 40α 12ml

These cooling eye drops from Japan provide a refreshing sensation to soothe tired, strained eyes often caused by screen time, dust, or dry environments.

If your eyes feel tired, overworked, or slightly irritated from long hours on the computer, reading, or exposure to air conditioning or dusty conditions, these drops offer quick, cooling relief. Expect an initial intense cooling sensation followed by comfort.

Wash hands. Tilt head back, gently pull down lower eyelid. Instill 1-2 drops into the eye sac (the space between the eye and lower lid). Close eyes gently for a moment; do not blink excessively. Use as needed, up to 5-6 times per day. Always check packaging instructions.

• Amount: Instill 1 to 2 drops in each affected eye.
• Frequency: Use up to 5 or 6 times daily, or as directed on the packaging. Do not exceed the recommended frequency.
• Method:
  1. Wash your hands thoroughly before use.
  2. Remove contact lenses before applying (wait 15 minutes before reinserting, check product label for specific contact lens compatibility).
  3. Tilt your head back and look up.
  4. Gently pull down your lower eyelid to create a small pocket.
  5. Hold the dropper bottle close to the eye without touching it. Squeeze gently to release 1-2 drops into the pocket.
  6. Close your eye gently for about 30 seconds to allow the drops to spread. Avoid squeezing your eyes shut tightly or blinking rapidly immediately after application.
  7. Wipe away any excess liquid from around the eye with a clean tissue.
  8. Replace the cap tightly after use.
• Tips: The cooling sensation can be intense initially; this is normal for this product. Avoid touching the dropper tip to any surface, including your eye or fingers, to prevent contamination.

• Immediately: You'll feel a strong cooling and refreshing sensation upon application, often described as intense but pleasant once you get used to it. Minor redness may appear temporarily clearer due to the vasoconstrictor effect. Eyes feel instantly more awake and less strained.
• Short-Term (with regular use): Consistent use within recommended limits may help maintain eye comfort during periods of strain or environmental dryness. These drops provide temporary symptomatic relief.

• Contact Lenses: Most Rohto eye drops, including this type, generally advise removing soft contact lenses before use. Wait at least 15 minutes after using the drops before reinserting lenses. Some specific formulas might be lens-compatible, but always check the product packaging instructions for ROHTO Cool 40α specifically. Using drops not intended for contacts while wearing them can cause discomfort or lens damage.
• Other Eye Drops: If using other medicated or lubricating eye drops, wait at least 5-10 minutes between applying different types of drops to avoid washing out the previous one. Consult a doctor or pharmacist if using prescription eye medication.
• Skincare/Makeup: Apply eye drops before eye creams or makeup. Wait a few minutes for drops to settle before applying products around the eye area.

These eye drops are intended to provide temporary relief from:

• Eye fatigue and strain (e.g., from prolonged screen use, reading)
• Minor eye irritation (e.g., from dust, pollen, dry air, swimming)
• Sensation of dryness
• Minor redness
• Blurred vision due to excessive eye mucus (helps refresh)

Note: These drops provide symptomatic relief and do not treat underlying eye diseases or infections. Consult an eye doctor for persistent or severe symptoms.

• Classification: In Japan, this product falls under Class 2 or 3 OTC (Over-The-Counter) Ophthalmic Drugs, intended for general eye fatigue and minor irritation relief. It is not a prescription medication.

While the full INCI list includes preservatives and buffers, the key functional components often include:

• Vitamins & Amino Acids: Such as Natural Vitamin E (d-α-tocopherol acetate), Vitamin B6 (Pyridoxine Hydrochloride), Potassium L-Aspartate. These aim to provide nourishment and support eye metabolism.
• Focus Adjustment Support: Neostigmine Methylsulfate may be included to help ease eye muscle fatigue related to focusing.
• Antihistamine: Chlorpheniramine Maleate helps reduce minor irritation and itching (e.g., from pollen).
• Redness Reliever (Vasoconstrictor): Tetrahydrozoline Hydrochloride constricts small blood vessels on the eye surface to temporarily reduce redness.
• Cooling Agents: l-Menthol and d-Camphor provide the characteristic intense cooling sensation.
• Preservatives & Buffers: Such as Boric Acid, Borax, Disodium Edetate, Benzalkonium Chloride (BAC/BAK), Polyoxyethylene Hydrogenated Castor Oil, pH adjuster. These maintain sterility and stability.

Note: Specific formulations may vary slightly by region or batch. Refer to the product packaging for the exact ingredient list.

• Scent: Contains l-Menthol and d-Camphor, giving it a strong, minty, cooling scent/sensation.
• Potential Irritants:
  • Cooling Agents: Menthol and Camphor can cause intense stinging or burning sensations, especially for first-time users or those with sensitive eyes.
  • Preservatives: May contain Benzalkonium Chloride (BAC/BAK), a common preservative that can cause irritation or dryness in some individuals with frequent, long-term use, and is generally not recommended for use with soft contact lenses. Check packaging.
  • Vasoconstrictors: Tetrahydrozoline Hydrochloride can cause rebound redness if used excessively or for prolonged periods.
• Recommendation: Patch testing is not applicable for eye drops. If you have known eye sensitivities or allergies, consult an eye doctor before use. Discontinue use if severe irritation, pain, or vision changes occur.

Read packaging instructions carefully before use.

• For External Use Only: Apply only to the eyes. Do not ingest.
• Do Not Overuse: Stick to the recommended frequency (usually max 5-6 times/day). Overuse of vasoconstrictors can cause rebound redness. Frequent need for drops may indicate an underlying issue requiring medical attention.
• Contact Lenses: Remove soft contact lenses before use unless the product explicitly states it is safe for use with lenses. Wait 15 minutes before reinserting. Preservatives like BAC/BAK can accumulate in soft lenses.
• Contamination: Do not touch the dropper tip to eyes, fingers, or any surface to avoid contamination. Keep the bottle tightly capped. Do not share eye drops.
• When to Stop Use and See a Doctor:
  • If you experience eye pain, persistent redness, or changes in vision.
  • If the condition worsens or persists for more than 72 hours.
  • If you have narrow-angle glaucoma (vasoconstrictors can be dangerous).
  • If you are allergic to any ingredients.
  • If the solution changes color or becomes cloudy.
• Storage: Store at room temperature, away from direct sunlight. Keep out of reach of children.
• Pregnancy/Breastfeeding: Consult a doctor before use if pregnant or breastfeeding.
• Other Conditions: Consult a doctor if you have other eye conditions or are using other eye medications.

• Texture: Clear, water-like liquid.
• Sensation: Provides an intense cooling and refreshing feeling immediately upon application, due to menthol and camphor. Rohto often rates the cooling level (e.g., on a scale of 1-5 or higher); this product is typically rated high (e.g., 5). It can feel like a strong minty blast in the eyes.
• pH: Formulated to be close to the natural pH of tears (around 7.0-7.4) for comfort, though specific pH may vary slightly.
• Formulation Type: Aqueous solution containing vitamins, amino acids, active pharmaceutical ingredients (vasoconstrictor, antihistamine, focus support agent), cooling agents, buffers, and preservatives.

• Intense Stinging/Burning: This is expected due to the strong cooling agents (menthol/camphor). Most users adapt after a few uses. If it's unbearable or persists, discontinue use.
• Temporary Blurred Vision: May occur briefly right after application as the liquid spreads. This should clear within a minute. If blurring persists, stop use and consult a doctor.
• Redness Worsens (Rebound Redness): Can happen with overuse of vasoconstrictor drops (like those containing Tetrahydrozoline). Stick strictly to the recommended frequency and duration. If redness increases, stop using and see a doctor.
• Dropper Tip Contamination: If the tip touches anything, bacteria can enter the bottle, risking eye infection. Discard the bottle if contamination is suspected. Always handle hygienically.

• Humidity & Heat: The refreshing, cooling sensation can feel particularly pleasant in Mauritius' warm, humid climate. Helps counteract the feeling of 'heavy' or tired eyes in the heat.
• Dust & Environment: Useful for providing temporary relief after exposure to dust, wind, or sea spray, common in coastal and urban areas of Mauritius. Helps rinse out minor irritants.
• Air Conditioning: AC environments can lead to eye dryness. These drops can provide temporary comfort, although a dedicated lubricating drop (artificial tears) might be better for chronic dryness.
• Screen Time: Ideal for students and office workers in Mauritius experiencing eye strain from prolonged digital device use.

• Vitamins & Amino Acids: Ingredients like Vitamin E, B6, and Potassium L-Aspartate are included based on the general understanding that these nutrients support ocular metabolism and health (Ingredient rationale). Vitamin E acts as an antioxidant.
• Vasoconstrictor (Tetrahydrozoline HCl): Temporarily constricts blood vessels on the eye surface to reduce redness (Ingredient rationale; established OTC mechanism). Efficacy for cosmetic redness relief is well-documented.
• Antihistamine (Chlorpheniramine Maleate): Blocks histamine receptors to provide relief from minor itching associated with allergens like pollen (Ingredient rationale; established OTC mechanism).
• Cooling Agents (Menthol/Camphor): Stimulate cold receptors (TRPM8) on the eye surface, creating the perception of coolness and refreshment (Ingredient rationale).
• Clinical Data: Specific clinical trial data for this exact formulation proving efficacy beyond temporary relief is typically proprietary to Rohto or not publicly released for OTC refreshers. Claims are generally based on the known pharmacological actions of individual active ingredients.

Brand claim—no public dataset available for independent verification of combined efficacy.

• Bottle Size: 12ml.
• Drops per Bottle (Approx.): A 12ml bottle contains roughly 240-300 drops.
• Uses per Bottle:
  • Using 1 drop in each eye (2 drops total) 3 times per day = 6 drops/day. Bottle lasts approx. 40-50 days.
  • Using 2 drops in each eye (4 drops total) 5 times per day = 20 drops/day. Bottle lasts approx. 12-15 days.
• Reorder Cadence: Depending on frequency of use, expect to reorder every 2 weeks to 2 months.
• Value: Offers potent cooling and multi-symptom temporary relief in one bottle, often considered good value compared to purchasing separate vitamin drops, redness relievers, and cooling drops.

No in-catalog pairings available today—this product works well solo for eye refreshment alongside your current skincare routine and daily sunscreen.

This product is an excellent choice if your primary goal is an intense cooling sensation to refresh tired or mildly irritated eyes.

• If you need primary lubrication for dryness: Consider preservative-free artificial tears or drops specifically formulated for dry eye relief.
• If you have significant allergies: Dedicated antihistamine eye drops might be more effective for persistent allergy symptoms.
• If you dislike intense cooling: Look for Rohto's milder formulas or other brands' general relief eye drops without menthol/camphor.
• If you wear contact lenses frequently: Seek eye drops specifically labelled as "safe for use with contact lenses."

Mindful-use: If you already have eye drops at home that address your needs, finish them first to avoid waste.

• Packaging: Comes in a small plastic dropper bottle (12ml) within a cardboard box.
• Applicator: Integrated plastic dropper tip designed for controlled dispensing. Features Rohto's "free angle nozzle" allowing application from various angles.
• Sustainability: Packaging materials (plastic bottle, cardboard box) may be recyclable depending on local facilities in Mauritius. Rohto has corporate sustainability initiatives, but product-specific details may vary.
• Storage: Store upright at room temperature (typically 15-25°C), away from direct sunlight and heat. Do not freeze. Keep tightly capped.
• Travel: The small 12ml size is very travel-friendly and usually permissible in carry-on luggage (check airline liquid restrictions).
