- 20/20 vision is a term used to express normal visual acuity (the clarity or sharpness of vision) measured at a distance of 20 feet.
- Myopia (Nearsightedness)

- Nearsightedness, or myopia, as it is medically termed, is a vision condition in which near objects are seen clearly, but distant objects do not come into proper focus.
- Hyperopia (Farsightedness)

- Farsightedness, or hyperopia, as it is medically termed, is a vision condition in which distant objects are usually seen clearly, but close ones do not come into proper focus.
- Presbyopia

- Presbyopia is a vision condition in which the crystalline lens of your eye loses its flexibility, which makes it difficult for you to focus on close objects.
- Astigmatism

- Astigmatism is a vision condition that causes blurred vision due either to the irregular shape of the cornea, the clear front cover of the eye, or sometimes the curvature of the lens inside the eye.
- Amblyopia (Lazy Eye)

- Lazy eye, or amblyopia, is the loss or lack of development of central vision in one eye that is unrelated to any eye health problem and is not correctable with lenses.
 - Strabism (Crossed Eyes)

- Strabismus occurs when one or both of your eyes turns in, out, up or down, and is usually caused by poor eye muscle control.
- Spots and Floaters

- Spots (or floaters) are small, semi-transparent or cloudy specks or particles within the vitreous, which is the clear, jelly-like fluid that fills the inside of your eyes.
- Color Deficiency

- Color vision deficiency is the inability to distinguish certain shades of color or in more severe cases, see colors at all.
- Eye Coordination

- Eye coordination is the ability of both eyes to work together as a team.
