Does sitting too close to the TV damage your vision?

Sitting closer than necessary may give you a headache, but it will not damage your vision. Parents of children and teens who habitually sit close to the TV should consider having their vision measured to screen for uncorrected refractive errors.

Does reading in the dark weaken your eyesight?

You may experience eye strain from reading in dim light, but it will not weaken your eyesight or harm the eyes. Reading in the dark is counterproductive because the parts of the eye that generate the clearest, most precise visual images require light in order to function.

Will using glasses or contacts weaken my eyesight? Will my eyes will eventually become dependent on them?

Vision correction (whether with glasses or contact lenses) focuses light rays entering the eye in order to create a crisp visual image on the retina. It is true that nearsighted children become more nearsighted up until age 30 or so, but don’t blame the eyewear! The focusing power of the eyes changes throughout life. That is one reason why routine eye exams are so helpful. Use of eyeglasses or contact lenses will not weaken eyesight or cause any focusing problem to worsen.

Can children with crossed eyes be treated?

The medical term for cross-eyed is strabismus (STRUH-BIZ-MUSS). There are several different causes for misalignment of the eyes, and a thorough eye exam is necessary to accurately diagnose the problem and its cause. Depending on the cause of the crookedness, some children with strabismus can be managed with prescription eyeglasses, whereas other kinds of strabismus require surgery. Prompt treatment is essential to protect the deviated eye from losing vision – a condition called amblyopia (lazy eye).

Is there anything you can do to prevent vision loss?

Most cases of vision loss can be treated. Depending on the specific disorder, vision loss can be halted, reversed, or even completely restored. See your doctor if you experience decreased vision, abrupt flashes of light, or the presence of a “curtain” that obscures your eyesight. Sudden, total loss of vision is a medical emergency – get immediate help.

Will using a nightlight in your child’s room contribute to nearsightedness?

Some researchers have suggested that use of nightlights may contribute to nearsightedness (myopia); however, there is not enough evidence to support this claim. Keeping a nightlight on in your baby’s room may actually help stimulate the infant’s visual development and eye coordination skills when they are awake.
