Factors That Affect Your Vision

Last updated 5 years ago

Visual acuity refers to the clarity or sharpness of your vision and is often determined using a Snellen Acuity Test in which you are asked to read letters and numbers at a distance of 20 feet. Individuals who have 20/20 vision are able to see objects at a distance of 20 feet that they should be able to see at that distance, whereas an individual with 20/40 vision is able to see objects at 20 feet away that most individuals can see clearly at 40 feet. Read on to learn more about which factors can affect your vision and increase the need for eyeglasses.

Increasing Age

Many people experience a decline in their visual acuity as they age due to a number of changes with their eyes. Older people are a greater risk for cataracts as the proteins within their corneal lens begin to clump together and impede their vision and often experience a decline in accommodation or their close-focusing abilities due to a condition known as presbyopia.

Family Medical History

Individuals whose family members have a history of declining visual acuity, cataracts, glaucoma, macular degeneration, or diabetic retinopathy may be at a greater risk for the same condition due to their genetic disposition. Your own personal medical history such as the presence of certain diseases can also interfere with your visual capacity.

Sun Exposure

Overexposure to the sun’s harmful UVA and UVB rays can severely increase your risk of a number of vision disorders. This includes but is not limited to cataracts, glaucoma, and retinal degeneration.

Nutrition

Proper nutrition is essential to maintaining the health and integrity of your eyes. Individuals who do not consume sufficient amounts of vitamin C, vitamin E, lutein, zeaxanthin, zinc, omega-3 fatty acids, and antioxidants may be at an increased risk for a number of eye conditions.
