Farsighted? But I can see clear at close range?!


Question: Farsighted? But I can see clear at close range?
What exactly defines farsightedness?

Is it still possible to be farsighted but have clear vision at close range? My vision is clear, not blurry at close range BUT it's extremely strainful and I'm forced to squint.

Can I still have farsightedness if I have clear vision at near range?

Yes.

While farsightedness (or hyperopia) is defined by most people as "you can see things far away but not up close", the definition is a bit more complex than that.

Your cornea, the crystalline lens, and the axial length of your eyeball are the three main things that determine what your refractive error is (such as hyperopia). In hyperopia, your eye basically does not have enough power to make things clear. However, you can use your accommodative focusing system to make up for the extra power you lack. Therefore, if you are under the age of 40 and have a good focusing system, you would be able to see clearly at all distances because your focusing system makes up for what your hyperopia is lacking.

If you have hyperopia, you will notice that you lose the ability to see things up close as you get older (over age 40) and get into that time frame where you need reading glasses. Because you lose the ability to focus and make up that extra power you need.

However, if you are have myopia (nearsightedness), it is because your eye has TOO much power. And since there is no way to take away power form the eye (accommodation can only add power), you see things blurry that are far away.

If you have astigmatism, you have too much power in one certain direction and either the right amount of power or not enough power in the other direction. Have you ever looked at your reflection on the backside of a spoon? Have you noticed how one direction of your face is squished and one direction is stretched? That's kind of how astigmatism works. And it causes blurry vision at all distances.

This is why hyperopes have a (+) in front of their glasses prescription, because they need more power to see clearly. And why myopes have a (-) in front of their glasses prescription, because they need less power to see clearly.

NOW IN YOUR CASE, it sounds as though you may have more hyperopia than your focusing system can handle. And that is why you are straining and working so hard to see clearly up close. You are pushing yoru focusing system to its limits to get the extra power you need, and you are feeling the eye strain for it.

You just need a pair of glasses and the eye strain will quite magically go away.

Farsightedness means when the eyeball is shorter then normal or the lens is weaker or the cornea is flatter.

It can cause problems with vision at all distances.

But in young people they could accommodate(put things into focus) so they don't have any difficulties.

Good luck
