Over-consumption of screens, excessive brightness or optical equipment that's not adapted to your needs can all cause eye strain.

What is eyestrain?

Eyestrain is often the result of over-use of our eyes. It's a temporary alteration in eye function, often associated with excessive effort on the part of the eye. Connected life and ubiquitous screens are therefore not good news for our eyes. But other factors can also contribute to eyestrain: high levels of light, cigarette smoke, dust, air conditioning and wind.

The symptoms of eyestrain are many and varied. Depending on the severity of the symptoms, the sensations may vary. And if they're not serious, eyestrain can quickly become bothersome and inconvenient. Generally speaking, the signals that should alert you are :

Feeling a drop in your vision (visual acuity) throughout the day.
Difficulty accommodating from distance to near vision.
Blurred vision.
Your field of vision is altered.
Double vision (diplopia).
A sensation of glare.
Irritated or red eyes.
A burning or stinging sensation in your eyes.
Regularheadaches.
A trembling eyelid.
Eye pain in or around the eyes.

Eye food supplements

Our eyes are exposed to a number of factors that can damage them: UV rays and smoking can prematurely age them and encourage the onset of eye diseases.

The role of ophthalmology

Ophthalmology is involved in several key areas:

Prevention and screening: Identification of visual disorders and eye pathologies at an early stage, notably through regular check-ups.
Diagnosis: Using sophisticated tools to assess the structure and function of the eye.
Treatment: Medical or surgical management of eye conditions.
Visual Rehabilitation: Helping visually impaired patients to optimize their residual vision.

Functional anatomy of the eye

The eye is a complex sensory organ, made up of several interdependent structures:

Cornea: the transparent part at the front of the eye, which plays an essential role in focusing light.
Crystalline: Inner lens used for accommodation, i.e. adjusting vision for near and far vision.
Retina: Light-sensitive tissue at the back of the eye, responsible for transmitting visual signals to the brain via the optic nerve.
Aqueous Humor and Vitreous Body: Liquids that maintain the shape and internal pressure of the eye.
Pupil and iris: regulate the amount of light entering the eye.

Common Ophthalmic Conditions

Refractive errors

These anomalies prevent light from focusing correctly on the retina:

Myopia: Difficulty seeing at a distance.
Hyperopia: blurred near vision.
Astigmatism: Distortion of images due to irregularity of the cornea.
Presbyopia: Age-related progressive loss of accommodation.

Eye pathologies

Cataract: Opacification of the crystalline lens, resulting in blurred or cloudy vision.
Glaucoma: A disease characterized by an increase in intraocular pressure, which can damage the optic nerve and cause vision loss.
AMD: Degeneration of the macula, responsible for central vision.
Diabetic retinopathy: Complication of diabetes affecting the blood vessels of the retina.
Keratitis and Conjunctivitis: Inflammations of the cornea or conjunctiva, often linked to infections or allergies.

Ophthalmology treatments

Glasses and contact lenses remain the most common solutions for correcting refractive errors. Corrective lenses can be adapted to meet specific needs, such as near, distance or progressive vision.

Eye drops, ointments and systemic medications are used to treat a wide variety of conditions:

Antiglaucoma eye drops: Reduce intraocular pressure.
Anti-inflammatories: treat ocular inflammation.
Antibiotics and antivirals: Treat bacterial and viral infections.

Modern ophthalmology offers a range of advanced surgical techniques:

Cataract surgery: Replacement of the opaque crystalline lens with an artificial lens.
Lasik and PRK: laser correction techniques for myopia, hyperopia or astigmatism.
Vitrectomy: Removal of the vitreous body in cases of retinal detachment or vitreous hemorrhage.
Intraocular implants: Correction of severe visual disorders or lens replacement.

Prevention and eye hygiene

Prevention plays a key role in ophthalmology to avoid serious complications:

Regular eye examinations: An annual check-up is recommended, especially after the age of 40.
UV Protection: Wearing sunglasses reduces the risk of cataracts and macular degeneration.
Contact lens hygiene: Clean and replace lenses as recommended to avoid infections.
Reducing Visual Fatigue: Observe the 20-20-20 rule when working at a computer screen.
