The fact is children may experience persistent sensitivity to light for a variety of reasons, but most often it can be attributable to a chronic condition—from migraine to concussion or even glaucoma.
Their eyes are sensitive to bright light, so they're more likely to open their eyes in low light. Don't worry if your baby's eyes sometimes cross or drift outward (go "wall-eyed"). This is normal until your baby's vision improves and eye muscles strengthen. Give your baby lots of appealing things to look at.
Your baby's eyes are not very sensitive to light in the first month after birth. In fact, the amount of light required for a 1-month-old infant to be aware that light is present is 50 times higher than that of an adult.
Still, there is no cure for persistent sensitivity to light and many of the underlying conditions.
Light sensitivity or “photophobia” is common in people diagnosed with eye conditions or sight loss. Light sensitivity is where the light level in the environment is too bright and causes discomfort. For some people, this discomfort can be extreme and can further reduce their usable vision.
Home care. Staying out of sunlight and keeping the lights dimmed inside can help make photophobia less uncomfortable. Keeping your eyes closed or covering them with dark, tinted glasses can also provide relief.
Migraines are the most common cause of light sensitivity. Up to 80% of people who get them have photophobia along with their headaches. Many of those people are light sensitive even when they don't have a headache. Other types of headaches can cause photophobia, too.
This vitamin is also a component of rhodopsin, a protein in your eyes that allows you to see in low light conditions ( 1 ). Vitamin A deficiency is rare in developed countries, but if unaddressed can lead to a serious condition called xerophthalmia.
This light sensitivity is often referred to as photophobia by medical professionals, and, for many, it can go away quickly. But for others, photophobia can be a persistent symptom of a diagnosed medical condition such as migraine, post-concussion syndrome or dry eye.
Your baby's vision: 2 to 3 months old
At this age, some babies may start to recognize faces (and treat you to a first smile) — but their sight is still fairly blurry. Babies who are born prematurely may take a bit longer to focus on your face, but don't fret: They will catch up developmentally.
What can a 3-week-old baby see? Your baby can still only see a few inches in front of them, and can mostly only make out black and white colors. 2 But they love looking at their parents' faces.
At four weeks of age your baby may be able to see more clearly than before. In fact, they will be able to see up to 18 inches in front of them. Now, it takes a lot of effort to focus so you may notice your baby looking a little cross-eyed at times.
Your healthcare provider will identify the cause of your photophobia by listening to your medical history, performing a physical examination and an eye examination, and possibly doing some specialized diagnostic tests as well.
Photophobia typically causes a need to squint or close the eyes, and headache, nausea, or other symptoms may be associated with photophobia. Symptoms may be worse with bright light. People with light-colored eyes are more likely to have sensitivity to bright light than those with darker-pigmented eyes.
Because light sensitivity can be difficult to diagnose, there are two new diagnostic tools that have been introduced: the ocular photosensitivity analyzer (OPA) and the visual light sensitivity questionnaire-8 (VLSQ-8). The OPA is an automated instrument that determines your light sensitivity threshold.
Being deficient in Vitamin D can also have a negative impact on eye health. Vitamin D deficiency has been associated with conditions such as age-related macular degeneration, diabetic retinopathy, uveitis, dry eye syndrome and impaired tear function.
Kale. Kale, spinach and other dark leafy greens like collard greens and turnip greens are packed with lutein and zeaxanthin, antioxidants that are stored in the eye's macula, which helps shield the eye from damaging light.
Eye problems are some of the most common issues associated with vitamin A deficiency. Dry eyes, or the inability to produce tears is one of the first signs of vitamin A deficiency. In rare cases, extremely low vitamin A levels can lead to complete blindness or dying corneas, characterized by marks called Bitot's spots.
Many autistic people experience hypersensitivity to bright lights or certain light wavelengths (e.g., LED or fluorescent lights). Certain sounds, smells, textures and tastes can also be overwhelming. This can result in sensory avoidance – trying to get away from stimuli that most people can easily tune out.
Sensitivity to light is known as photophobia. You may notice that when you go outside, it's difficult to keep your eyes open in the bright sunlight, or that even indoor lights cause discomfort. Light sensitivity is often caused by allergies but can also be the result of other eye conditions as well.
Changes in light sensitivity due to aging is completely normal. When adults reach their 60s, their resting pupil size shrinks, causing them to receive only one-third as much light as normal. This means it's harder for them to see in dim lighting, and their eyes become more sensitive to glare.
While photophobia is generally not considered an eye condition, veterans who experience photophobia as the result of an eye condition like conjunctivitis may receive VA disability benefits through ratings for the eyes.
