Farsighted

Farsighted's disease overview

What is

Vien Thi (Hyperopia, Hypermetropia, Farsightedness) is a common eye -related issue. People who are far away can see very good distant objects, but have difficulty focusing on near objects.

The vision is the deviation of refractive causes when the eyes are in a resting state, the light rays that come in parallel to the eyes will converge at the back of the retina. Want to see clearly, the right eye regulates to bring the image from the right in the retina.

congenital vision : Some children were born with farsightedness. In particular, some children have the ability to run out of vision when they are large, others may be progressed by farsightedness, need to be adjusted by glass.

Consequences of farsightedness:

  • Reduce the quality of life. In children, untreated vision can cause learning problems.
  • Eye fatigue: The untreated vision can cause eye narrow or eye stretch to maintain concentration leading to eye strain and headache.
  • unsafe when driving or operating heavy equipment

    • Causes of Farsighted's disease

    The cause of the vision is too flat or the front-axis of the eyeball is too short, making the image not converge in the retina as normal eyes but converging on the side. After the retina.

    Faradecimal has 3 main reasons including:

  • Due to congenital sphere or corneal not enough curvature
  • Due to not keeping the viewing distance when studying and working daily, often looking far away, making the glass body always stretching, gradually losing elasticity, losing the ability to bulge.
  • Because the elderly of the glass has been aging, the elasticity cannot be inflated.
  • Due to retinopathy or eye tumor: rare.

    • Symptoms of Farsighted's disease

    Symptoms of vision include:

  • Headache, temporal pain
  • eye pain, eye strain
  • Anxiety, fatigue
  • Must narrow the eyes or feel tired when working at a close distance while the ability to look far away is very good
  • The face of the vision: Due to seeing clearly the right eye trying to regulate is often accompanied by the contraction of the forehead, eyebrows and eyelashes that make the visional eyes have wrinkles.
  • The eyes of the farsighted people always tend to turn inside for the feeling that the eyes are very fine.
  • in.
  • Obmrusal pressure is often found on people who are visible due to the big eyelashes, narrow room money

    • People at risk for Farsighted's disease

    Eythena is a common eye and can affect any age but usually in children.

    There are many factors that increase the risk of vision, including:

  • Genetic factors: Children will be prone to farsighted if parents are farsighted

    • Having retinopathy

    There is an eye tumor

    Prevention of Farsighted's disease

    Methods to protect eyes and vision:

  • Periodic eye exams
  • Control chronic diseases such as diabetes or hypertension
  • Make a healthy diet with healthy foods. Eat fresh fruits and vegetables such as carrots, sweet potatoes and watermelon contains vitamin A and beta carotene.

    • Available to smoking

  • Study and work in the environment with full light
  • Doctors as soon as they notice abnormal symptoms
  • Protect your eyes from the sun by wearing ultraviolet barriers
  • Wearing glasses in accordance with the doctor's order

    • Diagnostic measures for Farsighted's disease

  • Eye examination
  • Test vision

    • Farsighted's disease treatments

    The vision in children

    often does not need treatment because the child's eye is quite flexible and this disability will be gradually improved over time. Children need to be encouraged for vision -related activities such as painting, coloring, reading stories ... to increase the refractive level of the glass, resulting in reduced vision (myopia). >Treatment of vision in adults wearing glasses can be treated by wearing glasses to change the convergence point of the light when entering the eyes, which is the type of glass starting with the number of signs, for example, for example Like +2.50.

    Patients can carry frames or contact lenses continuously or only when reading, working with computers or doing other things at close distance.

    Wearing glasses must be accompanied by a positive eye exercise regime to reduce the vision. Patients need to be monitored at least every 6 months to adjust the glass to suit the progression of the farsightedness.

    Surgery

    refractive surgery, such as Lasik surgery or corneal formation method with radio waves (CK), is another option to help adjust the vision.

    Surgery reduces or even eliminates the adjustment glasses.

    However, this method is not as safe as wearing glasses because some complications may occur:

  • Excessive vision
  • See the halo around the lamp

    • Infections

  • Dry eyes

    • Blind (rare) The methods of culture in the cornea being researched may be the option to adjust the vision in the future.
