Dry eye syndrome occurs when the eyes produce insufficient tears or poor-quality tears, leading to dryness, irritation, discomfort, or visual disturbance. Common vision problems include myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia. Vitreous degeneration refers to changes in the eye’s vitreous gel becoming more liquid or forming clumps, causing floaters. Macular degeneration involves deterioration of the central retina, leading to distorted, blurred vision and possible vision loss. Cataracts cause clouding of the eye’s lens and blurred vision; glaucoma results from increased eye pressure damaging the optic nerve and risking vision loss; pterygium is degeneration of conjunctival tissue that may cause blurred vision or increased astigmatism; pinguecula is a similar conjunctival growth that does not extend onto the cornea. We rely on our eyes constantly to observe the world around us, which places significant strain on them and increases the risk of eye problems. Understanding common eye diseases and vision conditions helps us care for and protect our eyes properly, recognize early symptoms, and seek timely treatment to reduce the risk of future complications.     Dry Eye Syndrome Dry eye syndrome occurs when the eyes cannot produce enough quality tears, leading to irritation, burning sensations, foreign body sensation, or excessive tearing. Common causes include prolonged screen use, dry or windy environments, and extended contact lens wear. Relief and prevention include using artificial tears, resting the eyes regularly, blinking frequently, and avoiding dry environments.     Refractive Vision Problems Refractive errors are among the most common vision issues across all age groups. They occur when light entering the eye fails to focus precisely on the retina, resulting in blurred vision. Types include:   Myopia (Nearsightedness) Myopia occurs when the cornea is too curved or the eyeball is elongated, causing light to focus in front of the retina. This results in clear near vision but blurred distance vision. People may squint or strain their eyes to see clearly and sometimes experience headaches.   Genetics plays a major role, especially if parents are myopic. Prolonged near work, limited outdoor activity, and excessive screen use can worsen symptoms.   Hyperopia (Farsightedness) Hyperopia may occur from birth or develop with age, resulting in difficulty focusing on near objects.   Congenital Farsightedness Occurs when the cornea is too flat or the eyeball is shorter than normal, causing light to focus behind the retina. Individuals typically see distant objects clearly but struggle with near vision. It is often hereditary.   Presbyopia Presbyopia results from aging as the eye’s lens stiffens and loses flexibility, reducing focusing ability. Symptoms include difficulty reading small print, eye strain, headaches, sensitivity to light, and reduced night vision.   Astigmatism Astigmatism occurs when the cornea has an irregular shape, causing multiple focal points instead of one. Symptoms include eye strain, blurred or distorted vision, glare sensitivity, and difficulty seeing at night.   Causes may include congenital corneal irregularities, injury, eye surgery, or conditions such as keratoconus.   Vitreous Degeneration The vitreous is a clear gel filling the back of the eye. Vitreous degeneration occurs when the gel liquefies or forms clumps, leading to floaters or flashes of light.   It commonly occurs with aging, especially after age 50 or in individuals with myopia. Untreated cases may increase the risk of retinal tears or detachment.   Common Eye Diseases Eye diseases can significantly affect vision if not properly diagnosed and treated. Understanding symptoms and treatments helps protect eye health.   Cataracts Cataracts occur when the eye’s lens becomes cloudy, reducing light transmission and gradually impairing vision. Common in older adults but may occur in younger individuals due to steroid use, trauma, or inflammation.   Glaucoma Glaucoma involves optic nerve damage often linked to high eye pressure. Acute cases may cause pain, blurred vision, halos around lights, headache, nausea, or vomiting, while chronic glaucoma may progress silently.   Pterygium and Pinguecula Pterygium is degeneration of conjunctival tissue growing toward the cornea, potentially causing blurred vision or astigmatism. Pinguecula is similar but does not invade the cornea.     Age-Related Macular Degeneration Age-related macular degeneration (AMD) affects the central retina, usually in individuals over 60, though increasingly seen earlier. It may cause distorted central vision, blurring, or dark spots.   While not curable, progression can be slowed through regular screening, healthy lifestyle habits, UV protection, balanced nutrition, exercise, weight control, and avoiding smoking.   Why Get Eye Checkups at Bangkok Eye Hospital?

Regular eye exams at least annually, adequate rest, hydration, balanced diet rich in antioxidants, avoiding smoking, and controlling blood sugar are important preventive measures.   How can vision problems in children be prevented? Encourage regular breaks during near work, limit screen time, promote outdoor activities, ensure adequate lighting, and schedule regular eye examinations.   What should I do if I experience dizziness or blurred vision? Consult an ophthalmologist for eye examination, adjust glasses or contact lenses if necessary, rest your eyes regularly, and avoid bright glare. Seek immediate medical attention if symptoms worsen.

Thin Cornea: Causes, Symptoms, and TreatmentsBangkok Eye Hospital A thin cornea refers to a condition where the corneal thickness is lower than normal, which can affect vision and overall eye health. Causes include natural aging, frequent eye rubbing, genetic disorders, or side effects from previous eye surgeries. Common symptoms include blurry vision, frequent prescription changes, distorted images, and high astigmatism. The cornea plays a vital role in focusing light into the eye. When the cornea thins, it may lead to complications, especially for those considering vision correction surgeries like LASIK. Understanding the causes and symptoms is essential for maintaining long-term vision clarity and preventing further thinning. Understanding the Cornea The cornea is the transparent, curved layer covering the front part of the eye. It helps focus light into the eye for clear vision and serves as a protective barrier against dust and germs. Normally, corneal thickness ranges between 520–550 microns, but it may thin with age. What Is a Thin Cornea? A thin cornea is typically defined as a corneal thickness of less than 500 microns (0.5 mm). It is not necessarily a disease and often requires no treatment. However, thin corneas can affect certain diagnoses—such as glaucoma—since intraocular pressure readings may appear lower than actual values. Corneal thickness also plays an important role in refractive surgery decisions. Patients with thin corneas may not be ideal candidates for LASIK. In such cases, surgeons may recommend alternative procedures such as PRK, ICL, FemtoLASIK, ReLEx SMILE Pro, or NanoLASIK, which preserve more corneal tissue. Does Wearing Contact Lenses Cause Thinning? Generally, wearing contact lenses correctly does not thin the cornea. However, prolonged use without proper cleaning or rest may lead to oxygen deprivation or corneal infections, which can gradually weaken or thin corneal tissue. Causes of Thin Cornea 1. Genetic Conditions Keratoconus is the most common cause, where the cornea gradually thins and bulges outward into a cone shape, leading to irregular astigmatism and blurred vision. 2. Eye Surgery or Injury Procedures like LASIK or PRK can thin the cornea, especially if excessive tissue is removed. Repeated eye injuries or untreated infections can also cause thinning due to tissue damage. 3. Systemic Diseases and Medication Autoimmune diseases such as Rheumatoid Arthritis or SLE can cause chronic inflammation, leading to thinning. Long-term use of steroid eye drops may also weaken corneal tissue over time. Symptoms of Thin Cornea Corneal thinning often progresses slowly. Key symptoms include: Blurry or distorted vision Frequent changes in prescription High or irregular astigmatism Difficulty focusing or double vision Diagnosis Eye doctors use advanced devices like a Keratometer to measure curvature or Corneal Topography to create a detailed map of the corneal shape. Detailed assessment is essential before undergoing any refractive surgery. Summary Thin cornea is a silent condition that can impact vision. Early detection is crucial. At Bangkok Eye Hospital, our specialists ensure accurate evaluation and personalized treatment planning for your eye health. FAQ: Frequently Asked Questions Q: Can corneal thickness be increased? A: No, corneal thickness cannot naturally increase as it is determined by the cornea’s internal structure. Care focuses on preventing further thinning. Q: What happens if thin cornea is left untreated? A: It may lead to worsening vision, irregular astigmatism, or corneal ectasia. In severe cases, acute hydrops or corneal perforation may occur, leading to permanent vision loss. Q: Can thin cornea be prevented? A: Yes — by avoiding vigorous eye rubbing, maintaining good hygiene, limiting contact lens wear time, and having regular eye checkups.
