1. Cataracts: Clouding of the eye’s natural lens, leading to blurred vision and eventual vision loss if left untreated.
2. Glaucoma: A group of eye diseases characterized by damage to the optic nerve, often caused by increased pressure within the eye, leading to gradual vision loss.
3. Age-related Macular Degeneration (AMD): A progressive condition affecting the macula, the central part of the retina, leading to loss of central vision.
4. Diabetic Retinopathy: Damage to the blood vessels in the retina caused by diabetes, leading to vision impairment or blindness if left untreated.
5. Dry Eye Syndrome: Insufficient tear production or poor tear quality, resulting in discomfort, redness, and fluctuating vision.
6. Retinal Detachment: Separation of the retina from its underlying tissue, which can cause sudden vision loss if not promptly treated.
7. Conjunctivitis (Pink Eye): Inflammation of the conjunctiva, the thin, transparent membrane covering the white part of the eye and inner eyelids, often caused by infections, allergies, or irritants.
8. Refractive Errors: Common vision problems such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism, which result from abnormalities in the eye’s shape or focusing ability.
9. Presbyopia: Age-related difficulty in focusing on close objects due to reduced flexibility of the eye’s lens, often occurring around age 40.
10. Corneal Diseases: Conditions affecting the cornea, the transparent outer layer of the eye, such as keratitis (inflammation), corneal dystrophies, and corneal abrasions.

These are just a few examples of the many eye conditions and diseases that can affect individuals of all ages. Each condition requires proper diagnosis and treatment by an eye care professional to preserve vision and prevent complications.
