Hello, I’ve been wondering what is the ‘resultant acuity’ when you actually put lenses that is NOT your full prescription.
Let’s say you have an acuity of
If you decide to wear a pair of -2.00, does this mean you have an acuity of -1.00 of spherical? Is the resultant acuity just x – y?
What if you wear a pair of -4.00 glasses? What is your resultant acuity? A +1.00 hyperopia? Since -3.00 – (-4.00) = +1.00. Yes?
Now, let’s say you wear your full prescription of -3.00s. This means you have 20/20 vision, or an acuity of 0. And you decide to wear a +1.00 lens ON TOP of your glasses again. What would happen? Will you see the world in -1.00?
I hope you’re able to follow my thought process here. What do you think?
