I need a second opinion

When we are quiet sure about a particular medical test, it is common for most people whom are diagnosed with a certain illness or disorders to seek for a second opinion.
Today, I experienced this particular scenario where-in I personally think that I badly need a second test from a medical expert.
I must have been in denial about not having a 20/20 vision, for I couldn't believe that at my age...I am experiencing a "refractive errors."
A refractive errors is a common vision problems that includes nearsightedness, farsightedness, astigmatism, and presbyopia.
But I will be closely tackling about a refractive errors that falls under "nearsightedness."
Nearsightedness mainly states that the person has a clear vision of an object closer to him/her, while when it was far, the vision became blurry or unclear.
This was the exact scenario I've encountered when the company I am currently rendering my service did a periodical medical assessment.
Most of my co-workers, usually tease me when they've notice that I am having a hard time checking if all words in the graphics are all spelled correctly.
I was just laughing at them and always divert my attention by cracking a joke about it.
Not until an eye-specialist hired by the company for a check-up, personally checked it.
I started to get a straight answer when I was asked to read a "Snellen Chart."

The traditional Snellen chart is printed with eleven lines of block letters. The first line consists of one very large letter, which may be one of several letters, for example E, H, or N. Subsequent rows have increasing numbers of letters that decrease in size. A person taking the test covers one eye, and reads aloud the letters of each row, beginning at the top. The smallest row that can be read accurately indicates the visual acuity in that eye.
I was shocked to find out that when I was asked to read the block letter located on the eight rows...I barely couldn't see it.
The guy who's conducting the eye examination uses another grade of an eyeglasses...and from there I was able to read and see it clearly.
As far as I can remember I was told that I have a 75/50 vision. I'm not sure if I am writing it right. But the 75 explains the condition of my right eye, and another 50 was for the left.
I was completely shocked and I have to admit that I worry about this.
But I know that worrying will not help me.
So, what I am thinking now is to seek a second opinion.
And from there, I will surely have a clear understanding of what I am going through right now.
