Buying Reading Glasses: How to Avoid 3 Common Mistakes

Written by: Joybuy Product Recommendation Officer

Finding it harder to read the letters in books, on your phone, or on packaging? It might be time for reading glasses. But buying reading glasses online can feel like a gamble. Many people make the same mistakes and end up with glasses that cause headaches or are tossed in a drawer after just a few weeks.

Before you make a choice, it's wise to know the most common pitfalls:

1. Choosing the wrong strength: The most common mistake is guessing the reading glass strength. Glasses that are too weak or too strong not only lead to blurry vision but can also cause eye strain and headaches.
2. Uncomfortable fit and materials: A frame that's too heavy, pinches behind the ears, or slides down your nose is a source of constant irritation. Cheap, rigid materials are often the culprit.
3. Paying for unnecessary extras: Some glasses are touted with special coatings that promise miracles. While certain features are useful, you sometimes pay for marketing terms that add little practical value to standard reading glasses.

What to Look For: The Core Specifications

To avoid buyer's remorse, it's important to focus on the specifications that truly matter. Below, we'll break down the three most important factors for you.

1. The Right Reading Glass Strength (Diopter)

The strength of reading glasses is expressed in diopters, such as +1.00, +2.50, or +3.00. The higher the number, the stronger the magnification. Although an eye exam with an optician always provides the most accurate result, you can make a reasonable estimate based on your age:

• 40-45 years: Usually start with +1.00 to +1.50
• 45-55 years: Often require +1.50 to +2.50
• 55+ years: Typically +2.50 or higher

Choose a strength that allows you to read comfortably at a distance of about 30-40 centimetres.

2. Frame Type and Material

The frame determines not only the look of men's reading glasses or women's, but also their comfort and durability. The three main types are:

• Full frame: Offers the most sturdiness and protection for the lenses. A good choice for daily, intensive use.
• Half frame: A balance between sturdiness and a lighter, more open feel. The bottom of the lenses is exposed, which can be useful if you often look over your glasses.
• Frameless: The lightest option, for a minimalist and almost invisible look. However, they are more fragile than full-frame models.

Also, pay attention to the material. TR90 is a popular material for sports glasses like cycling glasses because it is extremely lightweight, flexible, and durable.

3. Lens Features for Specific Situations

Not all glasses are the same. Depending on your lifestyle, extra lens features can make a big difference.

• Computer glasses: Do you work a lot behind a screen? Computer glasses often have a blue light filter. According to manufacturers, this can help reduce eye strain during prolonged screen use.
• Polarized sunglasses:Polarized sunglasses are ideal for driving and activities on or near water. The lenses filter horizontal glare from surfaces like a wet road or water, providing a calmer, clearer view. Fit-over sunglasses are a convenient option that you can wear over your regular glasses.
• Smart glasses: For the tech enthusiast, there are smart glasses or AR glasses. These combine vision correction or display with technological features, such as showing notifications or creating a virtual screen for movies.

Frequently Asked Questions

How do I know what strength of reading glasses I need?

The required strength depends on your age and the distance at which you read. A general guideline is +1.00 for ages 40-45, increasing to +3.00 for those 60 and over. For a precise measurement, visiting an optician is the best step. If you already know your strength, buying reading glasses online is much simpler.

Are computer glasses with a blue light filter useful?

Computer glasses are designed to reduce the amount of blue light that reaches your eyes. Some users report that this helps them experience less eye strain after a long day in front of a screen. Whether it works for you is a personal experience.

Can I wear reading glasses all day?

Standard reading glasses are only intended for seeing clearly at a short distance (reading). If you look into the distance with them, your vision will be blurry. For situations where you constantly need to switch between near and far vision, multifocal glasses prescribed by an optician are a more suitable solution.
