I Am Farsighted (I Have Hyperopia)
You probably had good distance vision when you were younger, but with time your vision has become poor at both near and distance. Your glasses probably need to be bifocals, trifocals, or progressives in order to see well at both distance and near (to correct farsightedness and presbyopia). If you wear contact lenses, the sign in front of the prescription power is a plus (+). Example: +4.50 soft contact lens power.
I Am Nearsighted (I Have Myopia)
You have poor distance vision without glasses and/or contact lenses. Your near vision is probably okay without glasses and/or contact lenses, but with glasses and/or contact lenses you probably require extra help at near (bifocals, trifocals, progressives, etc.). This is known as presbyopia. If you wear contact lenses, the sign in front of the prescription power is a minus (-). Example: -4.50 soft contact lens power.
I have Astigmatism
The cornea (front of the eye) is not perfectly round, but has more of a curved shape. Objects may appear to have a shadow or ghosted image without glasses and/or contact lenses. Your distance vision and near vision are probably both blurry, and you probably require extra help at near (bifocals, trifocals, progressives, etc.). It is common to have a combination of astigmatism and nearsightedness or farsightedness. If you wear soft contact lenses, the prescription probably has several numbers listed for the power. Example: -4.50 -1.25 x 180 soft contact lens power. If you wear gas permeable contact lenses, you probably have astigmatism.
I have Cataracts
This is a clouding of the lens inside the eye, most often due to increasing age. Vision typically appears cloudy or foggy, often with increased glare and light sensitivity. Cataracts occur in addition to other vision problems (nearsightedness, farsightedness, astigmatism, and/or presbyopia).
I have Presbyopia
If you are over the age of 40, you have probably begun to experience presbyopia. This is a normal age-related vision problem which usually becomes evident around the age of 40. You have difficulty focusing at near without extra help (reading glasses, bifocals, trifocals, progressives, etc.). You may have presbyopia only, or you may have a combination of other vision problems in addition to presbyopia (see more options below).
