We investigated a case of persistent blurred vision following cataract surgery, leading to the discovery of vitamin A deficiency in a 74-year-old man. Using advanced tests like full-field electroretinograms and optical coherence tomography, we noted significant retinal changes and low vitamin A levels.
After administering vitamin A supplements for three months, we saw remarkable improvement in his vision and retinal health. This highlights the importance of diagnosing vitamin A deficiency, especially in patients showing persistent vision problems post-surgery.

We examined a case involving a 55-year-old woman who experienced blurred vision due to a severe corneal condition linked to vitamin A deficiency.
After her previous bowel surgery, she suffered from malabsorption which led to this deficiency.
Despite initial treatments, her condition worsened until vitamin A deficiency was diagnosed.
Following intramuscular vitamin A treatment, she notably recovered her vision and overall health.

Our exploration focused on how vitamin A deficiency relates to blurred vision in a 63-year-old patient suffering from nyctalopia and severe rod dysfunction. Using various imaging techniques, we found that this individual's retinal abnormalities primarily affected the photoreceptor layer.
Notably, even after receiving vitamin A supplementation, his symptoms showed significant improvement, although the retinal lesions did not change. This suggests that while vitamin A treatment can help restore visual function, it may not reverse existing retinal damage related to deficiency.

Reduces eye fatigue
17 people found this helpful
Excellent protection for your eyes! With frequent computer use, I noticed eye strain. I was prescribed beta-carotene by my ophthalmologist, and within two weeks my eye fatigue diminished, along with improvements in vision clarity, particularly at night. Beta-carotene is a powerful antioxidant that transforms free radicals into harmless molecules, nourishing my eyes and preventing blurred vision. It supports overall eye health and age-related changes potentially leading to cataracts. This is a reliable and effective product, and I'm pleased to share my experience!

Eliminates dryness
4 people found this helpful
This beta-carotene has saved me from dry eye syndrome. I use contact lenses daily, and while drops were ineffective, after starting on beta-carotene, I found my eyes felt much lighter, my vision clearer without lenses, and importantly, the dryness has significantly decreased. I no longer rely on drops, even after long hours of lens wear. I was astonished to discover that I can comfortably wear lenses without the discomfort I previously experienced!

We evaluated the effectiveness of vitamin A eye gel as a protective measure for patients during head and neck surgery under general anesthesia. Our study involved 120 patients who were randomly assigned either vitamin A eye gel or erythromycin eye ointment, both paired with 3M transparent tape for eye protection.
Upon examining the outcomes, we found that vitamin A offered significant advantages, specifically in reducing corneal staining and discomfort symptoms like blurred vision compared to erythromycin. Thus, vitamin A appears to be a superior choice for preventing ocular complications during surgery.

We explored the effectiveness of retinol palmitate (VApal) ophthalmic solution for treating dry eye in a clinical trial involving 66 patients. Participants were split into two groups; one received VApal, while the other received a placebo.
Over four weeks, we tracked various measures, including improvements in blurred vision. Notably, the VApal group saw significant improvement in blurred vision and other subjective symptoms compared to the placebo.
The study confirmed that VApal is both safe and effective for dry eye treatment, presenting a viable option for those suffering from this condition.

Positive effect noted
My doctor prescribed beta-carotene after various tests revealed no issues, yet I was experiencing significant hair loss. I have definitely noticed an effect after using it, and I'm convinced of its positive impact on my vision as well.

Improves night vision
29 people found this helpful
I have ordered this preparation of oceanic beta-carotene many times. I drink it for a course of 20 days every 2-3 months. The dosage and bioavailability are crucial, with an adult's daily requirement being 2-7 mg, and here it is 7.5mg. A clear sign of vitamin A deficiency is reduced visual acuity, particularly night vision. With this natural product derived from ocean algae, my twilight vision has improved, the mucous membranes of my eyes are moistened, and the sensation of "sand" in my eyes has reduced. Unlike vitamin A, excess beta-carotene is non-toxic. I wish you all good health!

Stops vision deterioration
3 people found this helpful
The composition of beta-carotene is effective. I found the tablets appealing, being smooth and easy to swallow. After just a week, I noticed better visual acuity. My worsening vision has stabilised, allowing me to see the television screen clearly without glasses. Although tablets cannot completely restore vision, they can halt its decline. I aim to prevent total vision loss and plan to include lutein to enhance its benefits.

I order again, as it truly enhances my vision. One downside is that I stop taking it, and my eyesight declines once more.
