Colors After Closing the Eyes
Recently, I visited the doctor twice due to eye fatigue.
During the first visit, I was prescribed methylsulfate neostigmine, and during the second visit, I was given EyeHelp, with instructions to use it after finishing the first bottle.
However, yesterday, I experienced a slight stinging sensation in my right eye when applying the methylsulfate neostigmine before bed, which I hadn't felt before.
I usually take some time to lie down before falling asleep.
Previously, I only noticed floaters, which I believe are called "floaters," but yesterday, in addition to the floaters, I saw a blue shadow drifting around.
When I opened my eyes, it disappeared, but it reappeared after I closed my eyes for a while.
I would like to know if this could be related to the eye drops, or if I should start using the new EyeHelp.
Although I haven't finished the first bottle, it's been almost a month, and I've heard that it's best to discard eye drops after a month of opening.

Hello: First, methylsulfate newstamine is a topical soothing eye drop used to relieve symptoms such as dry eyes and fatigue.
The eye drops may cause some side effects, such as stinging or a foreign body sensation.
If you experienced stinging in your right eye while using methylsulfate newstamine yesterday, this could be one of the side effects of the medication.
If this discomfort persists or worsens, it is advisable to stop using the medication and inform your ophthalmologist to keep them updated on your condition.
Regarding the floaters and blue shadows you mentioned, these visual phenomena may be related to eye fatigue.
Prolonged use of digital devices or staring at a single point for an extended period can lead to these symptoms.
Generally, these phenomena are not serious issues, but if you feel uncomfortable or concerned, it is still recommended to discuss them with your ophthalmologist to determine the specific cause of your symptoms.
As for the timing of eye drop usage, if your doctor recommends stopping the use of a bottle of medication after one month, it is best to follow their advice.
Medications may have expiration dates and usage timelines; expired medications may lose their effectiveness or cause adverse reactions.
If you have unused medication, it is better not to extend the usage period, but rather to stop using it as advised and dispose of it.

When it comes to understanding eye symptoms, particularly those related to color changes and the effects of eye drops, it's essential to consider several factors. Based on your description, it seems you are experiencing a combination of visual phenomena, including floaters (often referred to as "flying mosquitoes") and a blue shadow that appears when your eyes are closed. Let's break down these symptoms and their potential causes.
Firstly, the presence of floaters is quite common, especially in individuals who are nearsighted or have experienced eye fatigue. Floaters are tiny clumps of gel or cells inside the vitreous, the clear gel-like substance that fills the eye. They can cast shadows on the retina, which is why you see them as small spots or strands drifting in your field of vision. These are usually harmless, but if you notice a sudden increase in floaters or flashes of light, it is crucial to seek immediate medical attention, as these could indicate a retinal tear or detachment.
Regarding the blue shadow you mentioned, this could be related to several factors. One possibility is that it is a visual phenomenon associated with the way your brain processes light and color, particularly in low-light conditions. When your eyes are closed, the pressure from your eyelids can stimulate the retina, leading to the perception of colors or shapes that aren't actually present. This is generally benign but can be disconcerting.
Now, concerning the eye drops you have been using, it's important to note that medications like methylsulfate newstamine (which I assume is a typo for a specific eye drop) can sometimes cause temporary discomfort or side effects, including stinging or burning sensations. If you are experiencing new symptoms, such as the right eye stinging when using the drops, it may be a sign of irritation or an allergic reaction to the medication. It’s advisable to stop using the drops and consult your eye care provider for further evaluation.
As for the EyeHelp drops, if they are intended to provide lubrication or relief from dryness, they may be beneficial, especially if your eyes are feeling fatigued. However, it is essential to follow the guidance of your eye care professional regarding the use of these drops, especially concerning the expiration date. Generally, eye drops should be discarded after one month of opening to prevent contamination and ensure safety.
In summary, while floaters and occasional visual disturbances can be normal, any new or worsening symptoms should be evaluated by an eye care professional. If you are experiencing discomfort with your current eye drops, it is best to consult your doctor before switching to a new product. They can provide personalized advice based on your specific situation and ensure that your eye health is managed appropriately. Regular eye examinations are crucial, especially if you have underlying conditions like myopia, to monitor for any changes in your vision or eye health.
