Hi! My name is Donald Jess. I'd like to ask what is Myopia and Hyperopia? Which is nearsightedness and farsightedness? I'm just confused.

Myopia or also known as nearsightedness is an eye disorder that is common. This happens when the light focuses in front of the retina than focusing on the retina. Having a blurred vision on objects that are distant is one of the symptoms of myopia. Another one is by squinting the eye, it makes the object clearer. This could be corrected by using prescription glasses that is either a bifocal or trifocal lens.
For farsightedness or Hyperopia, this is the opposite of myopia. The light is focused at the back of the retina instead of the front. Headaches or tired eyes due to reading are the common symptoms of hyperopia. The person is having difficulty seeing objects that are close in range. Having cross eyes is also a common symptom. Wearing of prescription glasses could correct this kind of eye disorder.
There is another type of eye disorder and that is presbyopia. The eye’s lens cannot focus which is the disorder and the use of prescription glasses could correct this. A person with presbyopia holds a reading material far away to be able to read. Most affected are people in their late 40’s. A common symptom is eye fatigue.
Regular eye examination is very important to check the present conditions of the eyes. Conditions will worsen if left untreated. A glaucoma test will also be done as part of the routine eye exam by an optometrist. Glaucoma builds up fluid in the eye resulting to pressure on the retina. If left untreated, it is irreversible and can cause total loss of sight. This cannot be treated by wearing prescription glasses but it rarely has symptoms.

Myopia or nearsightedness is a common vision condition in which you can see objects near to you clearly, but objects farther away are blurry.
If you have myopia or nearsightedness, the eyeball is too long, or the cornea is too steep, images are focused in the vitreous inside the eye rather than on the retina at the back of the eye.
Myopia may develop gradually or rapidly, often worsening during childhood and adolescence. Myopia tends to run in the family.
Nearsighted people often experience headaches or eye strain and might squint or feel fatigued when driving or playing sports.
Myopia may be corrected with eyeglasses, contact lenses or eye surgery.
Farsightedness or medically known as hyperopia, occurs when light entering the eye focuses behind the retina, instead of directly on it. This is due by a cornea that is flatter, or an eye that is shorter than a normal eye. People with hyperopia usually have trouble seeing up close, but may also have difficulty seeing far away as well.
The signs and symptoms of hyperopia includes difficulty seeing up close; blurred distance vision which occurs with higher amounts of hyperopia; eye fatigue when reading; eye strain (headaches, burning, pulling sensation); crossed eyes in children.
The treatment for farsightedness or hyperopia depends on several factors such as age, activities, and occupation. For young ones, they may or may not require glasses or contact lenses, depending on their ability to compensate for their farsightedness with accommodation. Contact lenses or glasses with convex lenses are required for the old ones.
Refractive surgery such as Laser-assisted in situ keratomileusis (LASIK), Clear lens extraction and replacement, Laser thermal keratoplasty (LTK) and intraocular contact lenses are all procedures that can be performed to correct both myopia and hyperopia.

Also called myopia, nearsightedness is a refractive error that produces clear vision for near objects but blurs objects seen in the distance. Nearsightedness is caused by an abnormally steep curvature in the cornea or by an elongated eyeball. As a result, light rays passing through the cornea converge at a point before the retina.
Farsightedness, or hyperopia, is a refractive error that causes near objects to appear blurry while distance vision remains clear. Hyperopia is a result of a cornea that lacks curvature or an eye that is too short. Light passing through the cornea is focused behind the retina. Images on the retina appear blurry and unclear.
Astigmatism is caused by an abnormally shaped eye that produces a cornea with a steep curve. Instead of a smooth, spherical shape, the eye is oval, resulting in unequal refraction. Light rays are focused at two different points on or before the retina, and this split focus produces distorted vision. Astigmatism, as well as myopia and hyperopia, are refractive errors that can be corrected with LASIK eye surgery.
