Determining the Right Strength of Reading Glasses | Tips for Presbyopia


As adults age, the prevalence of presbyopia becomes more apparent, impacting their daily activities. Understanding the condition and its symptoms, determining the right strength of reading glasses, considering factors when choosing reading glasses, and maintaining good eye health are crucial aspects for individuals experiencing presbyopia.

 How to Determine the Right Strength of Reading Glasses?

An eye examination by a professional optometrist is crucial to determine the appropriate Round glasses strength. Diopters play a significant role in identifying the required strength, and various testing methods are used to achieve accurate results.

Choose reading glasses strength ‘by age’

You may also be able to determine which strength of reading glasses you need by consulting a ‘power by age table’ like the one below:  

Age 40-44 – Recommended power +0.75 to +1.00 dioptre

Age 45-49 – Recommended power +1.00 to +1.50 dioptre

Age 50-54 – Recommended power +1.50 to +2.00 dioptre

Age 55-59 – Recommended power +2.00 to +2.25 dioptre

Age 61-65 – Recommended power +2.25 to +2.50 dioptre

If you find yourself torn between two sets of lenses, choose the glasses with the lower power. Opting for a pair of reading glasses that are too strong can cause discomfort compared to weaker powered glasses. This can lead to feelings of nausea and dizziness.

Select the right lens design.

Reading glass lenses come in a few categories; your choice depends on the vision correction you need.

Single vision lenses are designed to correct distance vision. They can be set to any focus, including near or intermediate vision.

Bi-focal lenses have a correction for reading on the bottom half of the lens and another for distance on the top.

Tri-focal lenses have three sections: distance vision, intermediate vision and near vision.

Progressive lenses have a smooth transition between distance and near focal areas without visible dividing lines. They can be more effective in correcting intermediate vision than bi- or tri-focals.

Your ophthalmologist should help guide you to the best lens design for your vision.
