Eyeglasses & Lenses - Los Alamitos Optometry
Trifocal lenses correct vision to allow you to see clearly at near, intermediate, and far distances. Near vision refers to the ability to clearly see objects like a book or phone screen about 14 inches from the eyes. Intermediate vision is used to see objects that are 18 to 24 inches away, such as a computer screen or car dashboard. Distance vision refers to the eyesight needed to view objects beyond an arm’s length. You rely on good distance vision when driving, playing sports, or watching TV.
For those who need vision correction to see all three distances clearly, speak with Dr. Yamanaka to determine whether trifocals can help.
Standard trifocal glasses are separated into three distinct sections, each one correcting a different type of vision, with a fine line demarcating each section. The top section corrects distance vision, the middle section corrects intermediate vision, and the bottom section corrects near vision. This allows you to see clearly at all distances just by shifting your focus to a different part of the lens.
Progressive trifocal glasses work the same way as standard trifocals, but don’t have the two distinct lines separating each section. Some patients report that progressive trifocals provide a smoother transition between visual zones.
Who Could Benefit From Trifocals?
Trifocals are popular among those with presbyopia, age-related farsightedness that makes it difficult to focus on near objects. Presbyopia is a natural part of aging and generally starts once a person turns 40 or 50. Trifocal lenses conveniently offer clear distance vision while eliminating the need to switch to different glasses when performing intermediate or up-close tasks.
