To clean water spots on prescription glasses, first rinse them in cool water. Next use a commercially available lens cleaning solution. This can be bought from an eyeglass store.
OD means Ocular Dexter, or Right Eye SPH means Sphere which is the spherical component of an eyeglass prescription
If you mean: (y2-y1)/(x2-x1) and (y1-y2)/(x1-x2) then either works out the same.
It depends what you mean by eyeglass. I have small telescope which weighs about 8 grams. I have an antique monocle which possibly weighs about half a gram.
It is not that easy. Some people believe that a simple set of numbers for a prescription can be plugged into a formula and somehow a new prescription will be generated. It is best to go to your local Optometrist and fully explain what kind of reading do you want to perform best. Ther will be a certain amount of positive (convex) lens power that will provide the needed amount of correction at the most… Read More
I'm assuming by y2 you mean y squared, so all you can do to factor that is take out a y so that you get y(x-y)
Each element is the mean of the corresponding elements. Thus, the mean of (x1, y1) and ( x2, y2) is [( x1 + x2)/2, (y1 + y2)/2]
Before you take prescription eyeglasses, you have to get a prescription. First, you need to go to an Optometrist (someone you examines your eyes). If they tell you that you need glasses they will write a prescription for you on a piece of paper. After you get the prescription, you need to go to an Optician (someone who sells prescription glasses). Once you go to one, find a pair of glasses that you like, and… Read More

On the other hand, the dream may be telling you that you are not seeing (understanding or comprehending) your current situation clearly. Perhaps you need to take a different point of view.
I think you have missed out an equals sign. If you mean x2 + y2 = 16, then the radius is 4.
y2 + y2 = 2y2
If x is 1 and Y is 5 and your x10 is really x to the tenth power (x10) and y2 is really y squared (y2) then: 110-52 = -24 there are an infinite number of answers depending on what it is that you mean with the notation that you have given.
yes eyeglass is a compound word
Eyeglasses are the most common method used to correct myopia. Concave glass or plastic lenses are placed in frames in front of the eyes. The lenses are ground to the thickness and curvature specified in the eyeglass prescription
The difference between ordinary eyeglass frames and the Versace eyeglass frames are that the Versace frames have been designed by a professional fashion expert and shaped to be extremely comfortable.
y6 x y2 y4 x y4 y2 x y2 x y4 y2 x y2 x y2 x y2
If you mean y2+8y+7=0 then it is a quadratic. y2+8y+7+9-9=0 y2+8y+16-9=0 (y+4)2=9 y+4=3 , y+4=-3 y=-1 , y=-7 So y can equal -1 or -7.
Rx stands for prescription, GRP for group. It is the group number of your prescription.

88 + 5y - y2 66 - 3y + y2 Subtract: 22 + 8y -2y2
It means "write". Basically you are telling the pharmacist to "write" or fill the prescription.
A monocle is the name for an eyeglass designed for one eye.
What do you want to convert it to? x2 + y2 = 2x If you want to solve for y: x2 + y2 = 2x ∴ y2 = 2x - x2 ∴ y = (2x - x2)1/2 If you want to solve for x: x2 + y2 = 2x ∴ x2 - 2x = -y2 ∴ x2 - 2x + 1 = 1 - y2 ∴ (x - 1)2 = 1 - y2 ∴ x… Read More
A single eyeglass lens is called a monocle and is rarely used nowadays.

This company now only sells prescription and non prescription sport glasses. I wish someone would bring them back into production. I could sell this frame again, since this style is popular once again.
The circle is centered at the origin and the length of its radius is 8 What is the circle's equation?
The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.
y2 there will me many solutions
The GCF is y2.
That is not an equation, but an expression.
