What Strength Glasses Do I Need

What Is The Average Age For Reading Glasses

What strength reading glasses do I need?

Seen in the image above, the soft lens in your eye gradually begins to stiffen as you approach middle-age.

This is due to the onset of a very common condition called presbyopia which means you’ll begin to experience difficulty focusing on nearby objects during daily tasks.

Reading or close-vicinity work can become more strenuous which can lead to headaches and frustration.

Even if youve never required to wear specs, reading glasses can solve the inevitable symptoms of presbyopia. Basic activities that have become difficult to focus-on can be corrected with a pair of good quality reading eyeglasses.

We sometimes get requests to gauge reading glasses strength by age, but this really isn’t a good measure compared to a full eye exam or atleast a close reading test.

Using your free reading glasses test, youll have discovered your required strength of corrective lenses.

If you do require corrective lenses, click the button below to browse our collection of quality reading glasses for men and women.

We offer blue light blocking glasses lenses to prevent premature ageing of the eyes which are emitted from phones, tablets and computers.

According to studies, presbyopia is increasing amongst young adults from prolonged exposure to digital screens.

Reading glasses strength is measured in dioptre.

Reading Lens powers range from +1.00, +1.25, +1.50, +1.75, +2.00, +2.25, +2.50, +2.75, +3.00 dioptre.

How Will You Use Your Readers

The lens power needed for reading glasses differs depending on purpose. The traditional reading distance is 14-16 inches, but its 18-20 inches for computer reading. Because the distances are not the same, the lens power will also be different. After calculating your lens strength for reading, reduce that by about half to find your correct power for reading a computer screen. This power might need to be adjusted based on the distance between the computer screen and your eyes.

See Your Doctor Regularly

Overall, it is best to see an optometrist every few years or as soon as you have questions or concerns about your vision quality. It is likely that you have a normal refractive error, but you may have a different condition in your eyes. You may need a different approach than over-the-counter reading glasses to help you.

Establishing a relationship with an optometrist or ophthalmologist means you can have your vision monitored by professionals as you age. This is incredibly important.

Reading Glasses For Presbyopia: Over The Counter Or Prescription

If you have presbyopia and have not developed other refractive errors earlier in life, your optometrist may recommend purchasing over-the-counter reading glasses. Typically, your optometrist will recommend reading glasses power based on your age.

  • 40 to 44 years old: You will use a power between +0.75 to +1.00 diopters to adjust your presbyopia.
  • 45 to 49 years old: Typically, this age group will need +1.00 to +1.50 diopters.
  • 50 to 54 years old: As presbyopia continues, this age range will need between +1.50 and +2.00 diopters.
  • 55 to 59 years old: For this age group, +2.00 to +2.25 diopter reading glasses are typically recommended.
  • 60 years old and older: For older adults, +2.25 to +2.50 diopters can adjust more progressed presbyopia.

Nonprescription reading glasses are sold over the counter with powers up to +3.00. After passing this convex lens number, you will need a prescription for reading glasses. Experts recommend that you pick the reading glasses with the lower power if you have two pairs of OTC glasses that correct your vision in about the same range. Wearing corrective lenses that are too powerful, even a little bit, for your eyes can cause eye strain, headaches, and make your vision worse faster.

You should also consider getting several pairs of reading glasses with different powers to help you perform different tasks, including working on a computer, watching television, and driving.

If you have a pair of readers that used to make reading a breeze, but now arent working as well, you probably need an updated pair.

In most cases, youll want to replace your readers with a stronger set because your eyes need more help as you age. If you find that youre holding reading material with your current readers farther away from your face than normal to see it clearly, then you might need stronger reading glasses.

If youre holding your reading material closer to your face than normal, though, then you need weaker reading glasses.

Either way, its prudent to book an eye exam and get new readers with the right lens strength.

The effect it has on melatonin is more than any other wavelength. Even a small amount of blue light will cause problems with your natural circadian rhythm and melatonin secretion.

In addition, you are likely to have less REM sleep leading to you feeling more tired when you wake up. Read more about how blue light filter will give you the best sleep of your life.

What Are Your Typical Habits

When choosing your reading glasses power, consider how you will most often be using your glasses. This can play a big role in how to determine reading glasses strength.

If you will typically be using your reading glasses for viewing things very small or up close, youll want to consider a stronger reading glasses power than what the age-based chart may suggest.

If youre going to primarily be using your reading glasses when youre at a computer, you should choose a lower reading glasses power. Most people view their screen from a greater distance than when theyre reading print material. The rule of thumb is that the farther the viewing distance, the less reading glasses power is needed.

It helps to improve the production of sleeping hormone to improve your sleepiness and maintain your body clock sleeping pattern.
