Some people are able to see well at a distance but struggle to focus on nearby objects. This condition can be caused by either hyperopia (far-sightedness) or presbyopia (inability to focus clearly). Others might see near objects clearly but would face difficulty while seeing distant objects which would appear blurred. This condition is caused by myopia (short-sightedness)

Your optometrist will also provide you with a prescription note which contains all the details and optical numbers for your eyeglasses to make you see clearly and better.
