How do dry eyes cause light sensitivity?
Dry eye syndrome makes the cornea more sensitive to light. In addition, researches have shown that computer users tend to blink less as they work on the computer for long periods. Computer use can result in dry eyes. Theralife has the complete oral dry eye treatment protocol for light sensitivity recovery.
Who suffers from light sensitivity?
Light sensitivity is common among people with chronic dry eyes, severe headaches, migraines, viral diseases, and blepharospasm.
What are the symptoms associated with light sensitivity (photophobia)?
Light sensitivity, also called photophobia, is an abnormal intolerance for light. Light sources such as sunlight, fluorescent, or other artificial lights trigger discomfort.
The person with light sensitivity will squint or have to close their eyes. Light sensitivity can cause pain, tears, and headaches.
The brighter the light, the greater the discomfort. People with this condition are affected by bright lights, but any light can trigger symptoms in extreme cases. The wavelength of the light may also matter. For example, blue light generally causes more trouble than other colors.
Significant changes in light levels can cause light sensitivity. For example, if you often spend time in darkened rooms, you will be less used to brighter lights and notice them more.
How is light sensitivity diagnosed?
If you are experiencing severe light sensitivity, you should consult an eye physician. Your doctor will perform a physical examination and also examine your eyes. Tell your doctor about the frequency and severity of your symptoms, as this will help them determine the cause.
Causes of light sensitivity
The exact area of the brain that causes light sensitivity is unknown. Light is carried in the visual pathways to the brain via the retina. The retina contains cells that detect light and form and projects them onto the optical path through the optic nerve. The light sensitivity may be partially caused by the rods and cones not recovering efficiently.
The retina also contains cells that sense light. Once these cells get turned on, these cells do not turn off.
Both types of cells in the retina may be involved in light sensitivity. These cells connect with the trigeminal system located in the deep brain center – and this explains how bright lights can cause pain. The melanopsin system also explains why people who are blind and thus have no formed vision can still experience light sensitivity.
Technically, photophobia is a symptom of another condition. Causes of light sensitivity include severe headaches, migraines, virus-caused illnesses, or blepharospasm (eye twitch). Uveitis, dry eyes, thinning of the retina, corneal abrasion, and nervous system disorders such as meningitis, encephalitis, and subarachnoid hemorrhage can also cause photophobia. It can also be a symptom of contact lens irritations, detached retina, refractive surgery, and sunburn.
Photophobia may also be a symptom of thyroid conditions or diabetes.
Dry eye syndrome makes the cornea more sensitive to light. In addition, researches have shown that computer users tend to blink less as they work on the computer for long periods. Therefore, computer overuse can result in dry eyes.
Color deficiencies in photophobia dry eye treatment
People with light eye colors are more likely to experience this condition because they contain less pigment, protecting the eyes from bright lights. Albinism is the lack of eye pigment, and it can have photophobia.
Light sensitivity can also be associated with total color deficiency (see only shades of gray), mercury poisoning, keratitis, iritis, rabies, botulism, and conjunctivitis.
Rare diseases in dry eye treatment
Light sensitivity can happen in rare diseases such as keratosis follicularis spinulosa decalvans (KFSD), a genetic disorder.
Medications in dry eye treatment
Some medications can have light sensitivity as a side effect. Some of these medications include doxycycline, tetracycline, diuretics such as furosemide, anti-malarial drugs such as quinine, antihistamines, blood pressure medications, digoxin, belladonna, and photosensitizing drugs can have this effect.
Prognosis of light sensitivity caused by dry eyes
The prognosis varies depending on the underlying cause of the condition.
With dry eyes, at least it is treatable – see TheraLife solution below.
Treatment for light sensitivity.
The only way to substantially reduce light sensitivity is to address the underlying cause. In many cases, removing the light sensitivity triggers is all it takes to cure this issue.
If photophobia is a side effect of a medication, sometimes your doctor can discontinue or replace the drug.
Treating migraines and blepharospasm may be helpful since they are the two most common causes of light sensitivity. Dry eyes can complicate chronic photophobia. Typical use of traditional dry eye treatments such as artificial tears, gels, and ointments is common.
Intermittent light sensitivity associated with migraines usually reduces with the use of migraine medications. Preventive migraine treatments can also help.
To alleviate the discomfort caused by photophobia, you should avoid direct sunlight and bright room lights, particularly fluorescent lights. If necessary, stay in a darkened room or wear sunglasses or glare control glasses. Some people find that tinted lenses help, particularly FL-41 tint, blue-blocking lenses, or red lenses.
Other natural treatments for dry eyes and light sensitivity.
Carotenoids – Eat more carrots
Research studies have shown that visual performance improves and light sensitivity (glare) decreases in subjects taking carotenoids (10 mg lutein and 2 mg zeaxanthin) per day.
Green leafy vegetables such as spinach, kale, and yellow carrots. have high levels of Lutein. Zeaxanthin is the pigment that gives paprika, corn, and saffron (and some other plants) their characteristic color.
Fruits and vegetables are an excellent way to obtain carotenoids. Daily juicing is a perfect form to promote intake.
Nutrients to preserve vision include bilberry, vinpocetine, l-lysine, some vitamins and enzymes, and fish oil. They are available as supplements.
If you are sensitive to the glare of headlights at night, you may need prescription glasses for night driving. See your eye doctor determine if that would be helpful. Keeping your eyes focused more on the edge of the road rather than approaching headlights may help you avoid the glare.
If you find that you have become very sensitive to light- visit a physician to determine the underlying cause of this condition. Sometimes it can be a symptom of severe disease.
