Computer Vision Syndrome (Digital Eye Strain)

Computer Vision Syndrome, also known as Digital Eye Strain, occurs due to prolonged use of computers, smartphones, or digital screens.
It results from focusing the eyes on a screen for extended periods without adequate breaks.
Symptoms include eye strain, dryness, blurred vision, headaches, and neck or shoulder pain.
Poor lighting and screen glare can worsen the condition.
Prevention includes adjusting screen settings, maintaining proper posture, and following the 20-20-20 rule for eye relaxation.

Eye Strain (Asthenopia)

Eye strain, or asthenopia, is a condition where the eyes become tired and uncomfortable after extended use.
It is commonly caused by prolonged screen time, poor lighting, or uncorrected vision problems.
Symptoms include eye pain, dryness, blurred vision, headache, and difficulty focusing.
It is usually temporary and improves with proper rest and eye care.
Treatment includes taking regular breaks, using correct eyewear, and following the 20-20-20 rule for eye relaxation.

Age-related Macular Degeneration (AMD)

Age-related macular degeneration (AMD) is a progressive eye disease that affects the macula, the central part of the retina.
It causes loss of central vision, making it difficult to read, drive, or recognize faces.
AMD is more common in older adults and may be classified as dry or wet type.
Symptoms include blurry or dark central vision and visual distortion.
Treatment focuses on slowing progression through medications, laser therapy, or nutritional supplements.

Glaucoma

Glaucoma is a group of eye disorders that damage the optic nerve, often due to increased intraocular pressure.
It can lead to gradual loss of peripheral vision and, if untreated, permanent blindness.
Symptoms in early stages are usually minimal, making regular eye check-ups crucial.
Risk factors include age, family history, diabetes, and high blood pressure.
Treatment includes medicated eye drops, laser therapy, or surgery to lower eye pressure and prevent further damage.

Cataract

Cataract is a common eye condition where the lens becomes cloudy, leading to blurred or dim vision.
It usually develops gradually with age but can also result from injury, diabetes, or prolonged UV exposure.
Symptoms include difficulty seeing at night, sensitivity to light, and faded colors.
Diagnosis is made through a comprehensive eye examination.
Treatment involves surgical removal of the cloudy lens and replacement with an artificial intraocular lens.

Strabismus (Squint)

Strabismus, commonly called squint, is a condition where the eyes do not align properly and point in different directions.
It can be constant or intermittent and may affect one or both eyes.
Symptoms include double vision, poor depth perception, and eye strain.
Early diagnosis is important to prevent amblyopia (lazy eye) and vision problems.
Treatment options include corrective glasses, eye exercises, vision therapy, or surgery in severe cases.

Amblyopia (Lazy Eye)

Amblyopia, commonly known as lazy eye, is a vision disorder where one eye has reduced vision because it and the brain do not work together properly.
It usually develops in early childhood due to strabismus, refractive errors, or visual deprivation.
Symptoms include poor depth perception, squinting, or favoring one eye.
Early diagnosis is crucial to prevent permanent vision loss.
Treatment includes eye patches, corrective lenses, vision therapy, or treating the underlying cause.

Presbyopia

Presbyopia is an age-related vision condition where the eye gradually loses its ability to focus on nearby objects.
It occurs due to hardening of the eye’s lens, usually after the age of 40.
Common symptoms include difficulty reading small print, eyestrain, and headaches while doing close work.
It is diagnosed through a routine eye examination.
Treatment includes reading glasses, bifocals, multifocal contact lenses, or corrective surgery.

Astigmatism

Astigmatism is a common refractive error where the cornea or lens has an irregular shape, causing blurred or distorted vision at all distances.
It occurs when light rays do not focus evenly on the retina.
Symptoms include eye strain, headaches, blurred vision, and difficulty seeing clearly at night.
It is diagnosed through a comprehensive eye examination.
Treatment options include prescription glasses, toric contact lenses, or refractive surgery.

Myopia (Nearsightedness)

Myopia, or nearsightedness, is a common eye condition where nearby objects appear clear but distant objects look blurry.
It occurs when the eyeball is too long or the cornea is too curved, causing light to focus in front of the retina.
Symptoms include squinting, eye strain, headaches, and difficulty seeing distant objects.
It is usually detected during routine vision tests.
Treatment includes corrective glasses, contact lenses, or laser vision surgery.
