Hello Mr. Vipin Agarwal. I am really sorry to hear about your problem. It is a common practice to say, "You're getting better, slowly however, a key investigation may be required." Based on your symptoms, it is evident that there might have been some error. Problems like white clouds, black spots, up-down visibility, etc. are not normal. Probable reasons for this include surgical error or corneal deformity. Initially, conduct a blood test and an eye check to get the full picture. Then, suitable treatment can be carried out. See an eye specialist for consultations. Stay healthy.

It's understandable to be concerned after your brother's eye procedures. The hazy vision he's experiencing can sometimes occur after lens surgery, especially with recent interventions. Since it’s normal to have some discomfort post-operation, it’s important to monitor his symptoms. If there are no signs of infection, the eye should heal well. The follow-up appointment will determine if the new lens will help restore his vision. Encourage him to maintain open communication with his eye specialist for the best guidance and reassurance.

Common eye problems such as dry eyes and floaters need treatment. It is advised to see an ophthalmologist to have a proper evaluation and treatment. 

It sounds like you have a refractive error, which means your eyes may not focus light correctly. The numbers you mentioned indicate mild nearsightedness and farsightedness, respectively. Wearing glasses can help correct your vision, allowing you to see clearly at various distances. It's essential to wear them consistently for the best results. If you experience any discomfort or changes in your vision, I encourage you to consult with an eye care professional. They can provide a thorough examination and ensure your prescription is accurate, giving you the best possible vision correction. 

Yes, you can give blood if you take­ ashwagandha every day and had Lasik surgery 3 ye­ars ago. The ashwagandha herb is safe and will not impact your blood donation. The­ Lasik eye operation you had some­ time ago also does not stop you from giving blood. Just make sure­ you feel good on the day you plan to donate­ blood.
