Yes, hypothyroidism can cause blurry vision, often due to inflammation and fluid buildup around the eyes (Thyroid Eye Disease or TED) or dry eyes, leading to pressure on the optic nerve or focusing difficulty, though it's more subtly linked than with hyperthyroidism (Graves' disease). Autoimmune thyroid conditions like Hashimoto's can also manifest with vision issues, causing dry eyes or blurred vision, requiring prompt medical attention for proper management.
Common symptoms include:
Like most medications, Synthroid comes with a list of side effects. One of the rarer side effects of Synthroid is that it may cause blurred or double vision and eye pain. These symptoms may stem from swelling caused by taking too much thyroid hormone or an adverse reaction to the medication, like an allergic reaction.
Thyroid eye disease is rare in children, but when it does occur, our pediatric oculoplastic specialists monitor and manage these patients. When necessary, they perform orbital decompression and eyelid surgeries.
Estrogen can also make the cornea less stiff with more elasticity, which can affect how light travels into the eye. The dryness and the change in refraction can cause blurry vision and can also make wearing contact lenses difficult.
While blurred vision often gets worse gradually, there are conditions that may cause blurring to start up suddenly. These types of conditions can be medical emergencies and include: Stroke or transient ischemic attack (TIA). A steep increase in blood pressure.
Symptoms of thyroid eye disease may include:
This condition also is called underactive thyroid. Hypothyroidism usually isn't linked to eye disease. In severe cases, however, hypothyroidism may cause swelling around the eyes. It also may cause a loss of hair in the outer part of the eyebrows.
Common signs
Hypothyroidism can affect anyone. It's most common among females over age 60, particularly after menopause.
Get Smart About Sleep
You might feel run down, even if you're taking medication. Yet all too often, “people with hypothyroidism don't get enough sleep, or the sleep they're getting isn't good quality,” Hatipoglu says. To ensure your body has a chance to rest and recover: Aim for 8 hours of sleep every night.
There are many risks of taking too much levothyroxine. The signs and symptoms of thyroid overmedication include anxiety, diarrhea, depression, elevated heartbeat, elevated blood pressure, fatigue, irritability, difficulty concentrating, difficulty sleeping, being overheated, and unprompted or unintentional weight loss.
Symptoms of thyroid eye disease include bulging eyes and seeing double. An eye doctor can prescribe prism glasses to readjust how light enters your eyes, helping you see better.
Unfortunately, routine thyroid screening for people at average risk is not cost-effective and, therefore, many cases are undiagnosed until they have symptoms. The end-stage of Hashimoto's is when your thyroid has become so damaged that you no longer have enough thyroid hormones and have to go on medication.
The thyroid gland needs the mineral iodine to make thyroid hormones. Iodine is found mainly in seafood, seaweed, plants grown in iodine-rich soil and iodized salt. Too little iodine can lead to hypothyroidism. Too much iodine can make hypothyroidism worse in people who already have the condition.
On the other hand, it is important to remember that some berries and citrus fruits like strawberries and peaches contain goitrogens. Since it can interfere with the thyroid glands' iodine uptake, eating these fruits of a larger quality can lead to hyperthyroidism.
For optimal thyroid health, the one key nutrient to focus on daily is iodine, found in foods like dairy, eggs, and seafood, but also selenium, provided by just a few Brazil nuts, is vital for hormone conversion, making eggs or Brazil nuts great morning choices, alongside a balanced breakfast with protein, healthy fats, and fiber for overall function.
What Are the Symptoms of Thyroid Disease?
The afternoon crash means your blood sugar has dropped too low for your brain and body to function normally, causing you to become drowsy, mentally foggy, tired, and unmotivated. Unstable blood sugar is notorious for making it difficult to manage an autoimmune disease such as Hashimoto's hypothyroidism.
A clinical eye exam is the first step in testing for TED. During this exam an ophthalmologist or optometrist will examine your overall eye health. They will look for visible signs of TED such as swelling, redness and bulging eyes. They may measure your eye movement, detect double vision and assess eye alignment.
Avoid stimulants on the run up to bed, especially when on medication, such as caffeine, alcohol and nicotine. Practice relaxation techniques such as meditation, yoga, deep breathing exercises and/or mindfulness before bed. This calms the mind and prepares it for sleep and can often help manage pain.
Eye problems are not commonly associated with hypothyroidism, an underactive thyroid. However, if you have Hashimoto's thyroiditis, you may be at higher risk for eye disease. Hashimoto's thyroiditis is an autoimmune condition that damages the thyroid gland.
Thyroid problems (hypo- or hyperthyroidism) show up as changes in energy, weight, mood, and body temperature, with common signs including fatigue, unexplained weight changes, anxiety/depression, feeling too hot or cold, hair loss, skin/nail issues, heart rate changes, and neck swelling (goiter), affecting metabolism and overall bodily function. Symptoms vary but often manifest as a slowed-down body (hypothyroidism) or an over-sped-up one (hyperthyroidism).
Diagnosis and Tests
If your healthcare provider thinks that you have thyroid eye disease, they'll order blood tests to check if your thyroid hormone levels and antibodies are too high or too low. Other tests your provider may request include: Ultrasound of the eyes. Computed tomography (CT)
Certain symptoms accompanying blurry or double vision should not be ignored and warrant immediate attention: Sudden Onset: If you experience sudden blurry or double vision, especially in one eye, it could be a sign of a serious condition, such as a retinal detachment, stroke, or optic neuritis.
