At any age, especially for aging eyes, regular eye care and examinations are very important to maintain eye health with good vision through early detection and prevention of disease. Early detection and intervention of any eye problems can reduce the risk of further worsening condition and provide more treatment options.

​

Does your health care include eye care? Even though you don’t think your eyes have any issues,  it is still very important to have regular eye exams so an eye care professional can help you correct or adapt to any changes in vision as well as detect eye problems early.

​

If you wear glasses or contact lenses, you may think about laser eye surgery to get rid of glasses. However, you should Learn who is a good candidate for eye surgery and what the risks and benefits of surgery are.

​

Common vision problems also come with age, such as difficulty reading small print, cataracts, and glaucoma, etc. Understanding the normal and abnormal conditions of eye health can help you decide whether you need specialized eye care services.

​

Visual acuity, i.e., VA, refers to the sensitivity and clarity of vision, which is mainly determined by the sensitivity of the center of the retina to visual images and the ability of the visual cortex in the brain to interpret images.

​

Prolonged use of computers and other digital devices is one of the most common causes of eye strain. The American Association of Optometrists calls this phenomenon computer vision syndrome or digital eye strain. People who stare at a screen for at least two hours a day were most likely to have this condition.

​

Staring at a computer screen is more likely to cause eye strain than reading printed material because people usually:
1) Rarely blink when using a computer (blinking is essential for moisturizing your eyes)
2) Looking at the digital screen at a less than ideal spacing or Angle
3) Devices that use glare or reflection
4) The text displayed on the device has poor contrast with the background

​

In some cases, underlying eye problems (such as eye muscle imbalances or uncorrected myopia) may cause or exacerbate computer eye strain.
Other factors that may exacerbate this situation include:
1) Screen glare
2) Improper posture
3) Computer workstation setup
4) Circulating air flow, such as from an air conditioner or a nearby fan

​

Eye strain does not cause serious or long-term consequences, but may gradually get worse and be unpleasant. This can make you tired and reduce your concentration. 

​

Eye strain is a common condition that occurs when you become tired from using your eyes too much, such as long distances driving or staring at computer screens and other digital devices.

Eye strain can be annoying. But it's usually not serious and will go away once you rest your eyes or take other steps to reduce eye discomfort. In some cases, the signs and symptoms of eye strain may indicate the presence of an underlying ocular condition that requires treatment.

​

Signs and symptoms of eye strain include:
1) Sore, tired, burning or itchy eyes
2) Prone to watery or dry eyes
3) Blurred or double vision
4) Headache
5) Sore neck, shoulders or back
6) Increased sensitivity to light
7) Difficulty to concentrate
8) Difficulty to open eyes

​

Common causes of eye strain include:
1) Watch the digital device screen for a long time
2) Keep reading without resting your eyes
3) Driving long distances and engaging in other activities that involve prolonged concentration 
4) Exposure to bright light or light
5) Trying to read in the dim light

​

Common eye diseases are: Central serous retinopathy, dry eye disease, sensitive ophthalmia, night blindness, blindness, amblyopia, astigmatism, trachoma, cataract, diabetic retinopathy, conjunctivitis, presbyopia, color blindness, isochronies iridesis, retinitis pigmentosa, central retinal artery obstruction, retinal detachment, myopia, hyperopia, needle eye, snow blindness, chalazion, glaucoma, floaters, etc.
