Understanding Eye Fatigue: Myths and Facts About Corneal Health
Thank you once again? Thank you for your response, Doctor. I am concerned that every time my eyes feel very fatigued and dry, it might affect the hardness of the cornea and sclera, thereby weakening their support. This worry makes my eyes even more fatigued. So, you mentioned tha...
Dr. Gao Pilin Reply:
Hello, Eye fatigue and dryness do not affect the hardness of the cornea and sclera, and therefore do not impact their structural support. A common sensation of soreness and pressure in the eyes is usually due to excessive use, leading to eye fatigue. This condition is referred ...[Read More] Understanding Eye Fatigue: Myths and Facts About Corneal Health

Does Dry Eye Syndrome Affect Vision and Increase Myopia or Astigmatism?
The eyes are often very dry? If dry eye syndrome is simply characterized by dryness without any corneal abrasions found during examination, will it affect vision? Does dry eye contribute to worsening myopia or astigmatism?
Dr. Gao Pilin Reply:
Hello, The main symptom of dry eye syndrome is discomfort characterized by a gritty sensation in the eyes. However, dryness in the eyes does not necessarily indicate dry eye syndrome; sometimes inflammation or fatigue can produce similar symptoms. A tear secretion test is requi...[Read More] Does Dry Eye Syndrome Affect Vision and Increase Myopia or Astigmatism?
Protecting Remaining Optic Nerve: Strategies for Vision Preservation

If you wish to ...[Read More] Protecting Remaining Optic Nerve: Strategies for Vision Preservation
How Dry Eye Syndrome Can Lead to Corneal Disorders
Corneal disease Dry eye syndrome can lead to corneal damage due to insufficient lubrication and moisture on the ocular surface. This lack of tear film can result in increased friction during blinking, causing epithelial cell damage and inflammation of the cornea. Additionally, th...
Dr. Gao Pilin Reply:
Hello, Tears have functions such as antibacterial action, immunity, cleansing the eyes, protection, and moisturizing the cornea. Therefore, insufficient tear production can lead to corneal abrasion and even infections, resulting in corneal disease. The conjunctiva may become sl...[Read More] How Dry Eye Syndrome Can Lead to Corneal Disorders

Understanding Fluctuating Vision: The Role of Ciliary Muscle Tension
Stubborn ciliary muscle!? A. Before dilation, the computer refraction showed a prescription around +8.50 (but at another hospital, it was +7.75). B. After dilation, the computer refraction was approximately +8.00. C. An optometrist used a funduscope (retinoscopy) and estimate...
Dr. Wang Zhishun Reply:
In theory, it is recommended to use long-acting cycloplegic agents for one week before performing automated refraction and subjective refraction, as this would yield the most reliable measurements. However, in clinical practice, if the goal is to prescribe glasses, using a trial ...[Read More] Understanding Fluctuating Vision: The Role of Ciliary Muscle Tension
Understanding Corneal Degeneration and Its Relation to Endothelial Cell Loss
Corneal issues Corneal degeneration refers to the reduction of corneal endothelial cells. Is corneal degeneration the same as corneal dystrophy? During an eye examination, will the corneal endothelial cells be assessed, or should I mention it separately to the doctor?
Dr. Gao Pilin Reply:
Hello, Corneal dystrophy is one of the causes of corneal degeneration. Endothelial cell dysfunction is just one type of corneal dystrophy. During an eye examination, the ophthalmologist will first perform a preliminary assessment of the cornea using a slit lamp. If necessary, t...[Read More] Understanding Corneal Degeneration and Its Relation to Endothelial Cell Loss
How Dry Eyes Affect Corneal Health and Vision
The eyes are very dry? Doctor, will corneal degeneration affect vision? Also, can dry eye syndrome lead to corneal hypoxia? Does dry eye syndrome affect the thickness and rigidity of the cornea? Thank you.
Dr. Gao Pilin Reply:
Hello, Corneal degeneration that occurs in the periphery is less likely to affect vision, but if it obstructs the pupil, it will impact visual acuity. Dry eye syndrome does not cause corneal hypoxia, and if there are no pathological changes, the thickness and rigidity of the co...[Read More] How Dry Eyes Affect Corneal Health and Vision

Do Eye Exercises Affect Myopia and Astigmatism Levels?
Eye movement exercises Does frequently performing eye exercises (such as blinking, tightly closing the eyes, and moving the eyeballs) increase or decrease the degree of myopia and astigmatism? Additionally, does eye fatigue and dryness affect corneal stiffness?
Dr. Gao Pilin Reply:
Hello, May: 1. Regular eye exercises do not increase or decrease the degree of myopia or astigmatism, but they can help give your eyes a rest; just avoid overly vigorous movements. 2. Eye fatigue and dryness do not affect corneal rigidity, but excessive dryness can make the corne...[Read More] Do Eye Exercises Affect Myopia and Astigmatism Levels?
Can You Develop Myopia at 28? Understanding Eye Strain and Vision Changes
Myopia issues Is it possible for me, at the age of 28, to develop myopia? I currently do not have myopia, but recently my eyes have been frequently sore. I have heard that tension in the extraocular muscles can compress the eyeball, leading to an elongation of the eyeball and sub...
Dr. Gao Pilin Reply:
Hello Wei: If you currently do not have myopia, it is generally unlikely to develop axial myopia at the age of 28. However, certain conditions such as corneal diseases or cataracts can still lead to myopia. Prolonged squinting can significantly affect the cornea and may lead to a...[Read More] Can You Develop Myopia at 28? Understanding Eye Strain and Vision Changes
Does Squinting in Adulthood Lead to High Astigmatism?
Habitual squinting? If an adult frequently squints while looking at things, will it lead to high astigmatism?
Dr. Gao Pilin Reply:
Dear Li: Squinting can affect astigmatism because the eyelids exert pressure on the cornea. Each individual's corneal elasticity varies, leading to different degrees of astigmatism. Although resting initially may help restore vision, prolonged squinting can result in irrever...[Read More] Does Squinting in Adulthood Lead to High Astigmatism?
Impact of Squinting on Cornea: Dry vs. Non-Dry Eyes
Squinting action Excuse me, doctor, I would like to ask if squinting when the eyes are not dry and squinting when the eyes are dry have the same effect on the cornea?
Dr. Gao Pilin Reply:
Dear Ben: Squinting is not good for your eyes, whether they are dry or not, as it can cause corneal pressure leading to astigmatism. I'm not sure what the motivation for squinting is. If it's because you can't see clearly, I recommend wearing appropriate glasses to...[Read More] Impact of Squinting on Cornea: Dry vs. Non-Dry Eyes

Does Squinting or Closing Eyes Increase Astigmatism and Change Eye Shape?
Eye fatigue Does squinting or tightly closing the eyes when experiencing eye fatigue and dryness increase astigmatism or change the shape of the eyeball?
Dr. Gao Pilin Reply:
Hello Ben: Forcefully closing your eyes may temporarily cause slight deformation of the cornea, which could lead to some astigmatism. However, the eyeball is elastic and will quickly return to its normal shape, so it should not result in permanent astigmatism or deformation. Puzi...[Read More] Does Squinting or Closing Eyes Increase Astigmatism and Change Eye Shape?
