What are Reading Glasses?

Reading eyeglasses improve up-close vision. Many people wear them when looking at a computer screen or reading. 

Some reading glasses feature blue light blocking lenses out the light from technological devices. Reading glasses have various strengths and can be prescription or over-the-counter (OTC).

Usually, vision experts recommend that OTC reading glasses only be used on a short-term basis. They are also best for people with the same vision strength in both eyes. 

Prescription glasses are a better option over reading glasses if you have:

  1. Different prescriptions in each eye
  2. Astigmatism that causes blurred vision
  3. A need to wear reading glasses for a long time

How to Tell if You Need Reading Glasses 

Most people realize they need reading glasses when they are straining to read, especially when words are written in small print. 

They might move the text further from their eyes or shift materials around until their eyes can focus.

The most definitive way to know if you need reading glasses is to undergo a professional eye exam. However, this isn’t always necessary. 

The following are an indication that reading glasses might help you see better:

You’re getting older

People usually begin to experience a shift in vision after 40. Some people need reading glasses as young as 20 or 30, especially if they deal with eyestrain. This is more common now because of frequent phone and computer use. 

Needing more light to see

If you notice it’s tougher to see in dimmer light than usual, it could indicate that you need magnification. Reading glasses might help if you find yourself turning up the light when trying to read,

Feeling fatigued

Constantly having to put significant effort into seeing clearly is exhausting. Feeling tired after relaxing activities like reading could be because you are straining to see clearly.

Try wearing reading glasses the next time you read and see if you feel as tired as before.


Headaches are a big indicator that someone’s vision needs support.

It can be a sign of other problems, so a medical examination can rule out other more serious health concerns related to headaches. In some cases, investing in a pair of reading glasses might be enough to ease the pain of vision-related headaches.

Sometimes headaches are from looking at screens too long, making reading glasses with blue light protection a great option.

Lowest Power for Reading Glasses

Reading glass power is measured in units called diopters. The lowest strength is usually 1.00 diopters.

Highest Power for Reading Glasses

Glasses increase in strength by factors of .25 (1.50, 1.75, 2.00). The strongest reading glasses available are 4.00 diopters.

Can You Get a Different Power for Each Eye? 

Yes, but you won’t find them as easily as generic glasses. 

In most cases, you’ll need prescription reading glasses if you have two different strengths.

How to Pick the Right Prescription Reading Glasses 

Your eye doctor will help you choose the right prescription reading glasses. They’ll create a prescription for your lenses after you undergo a vision examination.

Once you have a prescription, you can choose frames that can be customized to the prescription and your eyes. 

When choosing prescription reading glasses frames, consider:

  • Price
  • Quality of materials
  • Durability
  • Fit
  • Frame style
  • Blue light protection
  • Shipping cost or whether free shipping is offered if you order online
  • Whether you can return readers that don’t fit or work for you

If you don’t need prescription reading glasses, you’ll likely be on your own when making your choice. 

Most people use some trial and error when they shop for OTC reading glasses. 

You can try on a few different magnification strengths and styles when they shop. Some even want a different style or frame based on what they’re doing or where they are wearing their glasses. 

Do Cheap Reading Glasses Work?

Yes. For many people, inexpensive OTC reading glasses are all they need to see better when looking at close-up materials. 

The key to making cheap reading glasses work for you is to choose the right lens type magnification. 

It helps to try a few different magnification strengths before making your purchase. Also, remember that the magnification you need might increase as you age. 

Alternatives to Reading Glasses

If you’re someone who doesn’t want to wear reading glasses, there are other options available. 

Laser Surgery

Sometimes, people opt to undergo LASIK or PRK surgery to improve their vision. This is more common for people who have non-age-related vision issues. These procedures correct nearsightedness, farsightedness, and astigmatism. 

Refractive Lens Exchange

Another alternative to reading glasses is refractive lens exchange. This procedure removes that eye’s natural lens and replaces it with an intraocular lens implant. The steps are essentially the same as cataract surgery.


Monovision corrects someone’s dominant eye for distance vision and corrects their non-dominant eye for near vision. 

In response to these corrections, the brain makes the needed vision changes automatically. Monovision allows for a change in the range of focus without the need for glasses or contact lenses.

Keep in mind that these corrective alternatives to readers give you blue light protection. It might be a good idea to invest in these lenses to protect your eyes, even after your vision is corrected. 


Reading glasses help improve up-close vision when you're straining to read. Your eye doctor can perform an eye exam to determine whether you need reading glasses. Aside from reading glasses, laser surgery, refractive lens exchange, and monovision can also improve your vision.
