Eye prescription is +0.25x-1.0. So my power is "+", but spherical equivalent is "-". Am i myopic or hyperopic? Is near or far vision better?

Eye prescription is +0.25x-1.0. So my power is "+", but spherical equivalent is "-". Am i myopic or hyperopic? Is near or far vision better?

Depends...: +.25 is negligible, so you can say you're emmetropic. However you do have astigmatism, so you are astigmatic . Technically, you're hyperopic with astigmatism. With current data, i couldnt tell you whether near vision or distance vision is better, depends on whether you have presbyopia or not. If you don't have presybiopia, then they are equal. Hope that helps, but it can get confusing.... ...Read more

Is it possible for nearsightedness to become farsightedness?

Yes: Though uncommon, there are ways for someone to change from near to far-sightedness. The most common way is from natural aging (growth of eye) and from cataract development (change in lens power). Other possibilities include laser vision, trauma, corneal scarring, refractive lens exchange, corneal ectasia, and retinal pathology. ...Read more

I was nearsighted and also a little farsighted. Is that even possible?

Yes: It is possible to have some distance vision and some near vision and still need glasses to get your best corrected vision. These terms are confusing and really just refer to where the light focuses on the retina. Also losing reading vision after 40 yrs of age is a separate problem called presbyopia. This sometimes gets confused with the other issues. ...Read more

How can you be nearsighted, farsighted, and astigmatism?

How can you be nearsighted, farsighted, and astigmatism?

Not commonly: These are the three basic errors of refraction along with presbyopia which is the farsightedness of older folk. Astigmatism, an ovalness of the eye can coexist with all of these. Near and farsighted are opposites and do not coexist although presbyopia is a type of farsighted which then can exist with underlying myopia. Ask your ophthalmologist to tell you which of these you have. ...Read more

Why is the cost between nearsighted glasses and farsighted glasses so vast?

More complexity: There are many factors that determine glasses cost. In a forty-ish person, you are probably referring to needing a multi-focal lens for the first time. These lenses are more complex, and therefore more expensive than single vision lenses. ...Read more

How can you be farsighted and nearsighted together?

How can you be farsighted and nearsighted together?

Focus problems: Focusing or far away objects requires a different combination of eye lens, cornea and retinal distance from the lens than focusing on nearby objects. The focusing system can go awry in both the far away combinations and/or the nearby combinations usually because of problems with the shape of the lens for each type of focus. ...Read more
