Detailed Answer:
Hello,

Welcome to Health Care Magic.
My name is Dr Muhammad Ahmad & I will look into your problem.

I have gone through your query and would try to help you in the best possible way.

1 - Retinitis pigmentosa:
Retinitis pigmentosa (commonly referred to as "RP") is a disease characterized by loss of the light sensing photoreceptor cells that line the back of the eye, like the film of a camera. Usually the rod photoreceptors (responsible for night vision) are affected first, which is why loss of night vision (nyctalopia) is usually the first symptom. Daytime vision (mediated by the cone photoreceptors) is usually preserved until the late stages of the disease. Mottling of the retinal pigment epithelium with black bone-spicule pigmentation is typically indicative (or pathognomonic) of retinitis pigmentosa. Other ocular features include waxy pallor of the optic nerve head, attenuation (thinning) of the retinal vessels, cellophane maculopathy, cystic macular edema, and posterior subcapsular cataract.


2 - Retinal detachment:

Not likely in your case.

3-Certain medications, such as phenothiazines.

4-Pathological myopia.

6-Cataract:
This doesn't seem to be your case as your optician cleared you plus cataract also causes issues in day time.

7-Vitamin A deficiency:
Rods contain a pigment called rhodopsin. When light falls on rhodopsin, it undergoes a series of conformational changes ultimately generating electrical signals which are carried to the brain via the optic nerve. In the absence of light, rhodopsin is regenerated. The body synthesizes rhodopsin from vitamin A, which is why a deficiency in vitamin A causes poor night vision.

My opinion:

Brain usually doesn't present with eyes site issues at night alone it usually presents with permanent symptoms.

I would suggest you to consider increasing intake of vitamin A, as a vitamin cocktail in multi vitamins or taking foods high in vitamin A like carrots, sweet potatoes, liver, fish.

You can also take a second opinion or discuss other possible causes with your doctor retinitis pigmentosa can be a cause, usually it involves rods first so night vision is effected first.

Hope I have answered your query. If you have any further questions, I will be happy to help if not then don't forget to close the discussion and rate it.

Wishing you good health !!
