Eyes, beauty & pretty

My position requires me to look at the computer all day. Is that a possible cause for my white eye becomes dull and kinda look yellow like that. I had see doctor last time. Doctor has told me it is only a dusty environment/gaze and I have been given a drop liquid for it. But it was not a solution and my eye still dull and yellow like very tired person.
I also checked my liver but function very well. It sounds more like a nutrient deficiency so I went back to clinic and done blood test for nutrient check. All are ok except for the high bad cholesterol in the result.

I found this inner shine prune essence from brands that helps to nourish and protect eyes to keep them fresh and bright all day long. It claimed that we can forget all about having tired and bleak eyes.

I have tried twelve bottles but still don’t see the different. Of course lah coz I took them consecutively for two weeks and for sure there are no major improvements. I wonder how long I should take it. Some people suggest that continuously taking for 3 weeks and then take 2 weeks consecutively. I do not know. But I have to try it and see the different. What say you?
