Do You Know What the Prescription Number of Reading Glasses Means?

Most of us eventually need some help reading small texts. As our lives progress, the surface of our eyes becomes more and more inflexible, which makes it difficult for us to focus on small or nearby objects and words. Reading glasses is designed to improve your vision. You can buy a series of different prescription glasses, such as photochromic reading glasses or varifocal reading glasses. Your optometrist will give you a prescription with all the information you need to buy the correct reading glasses.

Reading Glasses Prescription

Whether it's small round reading glasses or breakaway reading glasses, their reading glasses prescription looks almost the same as the standard glasses prescription, but the number itself has some small differences. A prescription for reading glasses usually has a number with a plus sign, indicating that the lenses can improve the eye's ability to focus on close objects. The larger the number, the more vision you need to correct, and vice versa.

1.25 reading glasses

Nearsighted reading glasses, at the range of 1.25, are suitable for people with low vision to moderate myopia. If the strength below 1.00 is not strong enough, you can choose lenses from the range of 1.00-2.00.

2.25 reading glasses

For presbyopia glasses, 2.25 is a relatively high strength prescription, suitable for middle-aged and elderly people.

This is a powerful prescription for people with medical problems such as macular degeneration. If you need it, your vision specialist will recommend it for your presbyopia glasses.

Principles of prescription for reading glasses

(1) The power of reading glasses must be selected on the basis of measuring the refractive state and the distance of the near point under the guidance of retinoscopy. It is not allowed to directly select the power of the lens according to the age of the customers without formal optometry.

(2) Optometrists should pay attention to the professional requirements of patients, and carefully determine the prescription of glasses according to the specific work requirements of patients, so that patients can obtain indestructible reading glasses and good quality reading glasses.

(3) Pupil distance needs attention. Reading glasses are usually adjusted with the help of lenses, but the double internal rectus muscles still have to contract for convergence, which is prone to eye fatigue. In order to eliminate muscle eye fatigue, or to add a prism with the base inward on the lens or use it, the lens eccentricity can produce the corresponding prism effect.

Is high magnification reading glasses suitable for you? Or is progressive bifocal reading glasses more suitable for you? The only way is to get the latest prescription from an eye care professional. They will tell you the exact prescription number and other details, such as your pupil's distance, which is as important as your prescription ball count.
