Best Reading Glasses to Buy Online in 2025

Strength
Reading glasses typically range from +0.25 to +2.50 diopters (the unit of measurement for eye prescriptions), although the average starting strength is usually around +0.75. In rare cases, the strength of reading lenses can be up to +4.00.
“The advice for buying reading glasses online is similar to buying ready-made reading glasses at the pharmacy: It’s a convenient option but it’s not a good idea for everyone,” says Dr. Ravi Goel, clinical spokesperson for the American Academy of Ophthalmology. “If you have different prescription needs for each eye, if you have astigmatism, if you have high-power or more complex prescription needs, you should consult an eye care professional for updated prescription glasses. »
Reed supports this, adding: “The wrong prescription can lead to headaches, eye strain, or even nausea. If you choose to purchase online, we recommend selecting a lower power when deciding between two strengths, as it is generally a safer choice, and lenses that are too strong tend to cause more discomfort than those that are slightly weaker.”
Goel notes that anyone over the age of 40 should see an ophthalmologist for a medical eye exam, as this is the age when presbyopia and potentially blinding eye diseases typically begin to develop. Additionally, not all eye diseases begin with visible symptoms.
Type of reading glasses
“There are four main types of reading glasses: single vision, bifocal, trifocal and progressive,” explains Goel, defining them as follows:
- Single vision reading lenses are generally designed to correct near vision only.
- Bifocal lenses have a correction for reading on the lower half of the lens and another for distance on the upper half.
- Trifocal lenses have three sections: distance, intermediate and near vision. Reed says these can be particularly helpful for people over 50 who face reduced depth of concentration.
- Progressive lenses have a smooth transition between far and near focal areas without visible dividing lines. “They provide a more natural look and smoother transition between different viewing distances,” adds Reed.
“When generic over-the-counter readers are no longer enough, prescription reading glasses – also called single vision readers – are a great next step. They are custom made by an ophthalmologist to correct astigmatism, uneven prescriptions or other specific vision needs,” says Reed. “For those who need multiple levels of vision correction, there are multifocal lenses.”
The best lens material
“It depends on lifestyle,” says Goel. “For example, if you spend a lot of time outdoors, you may prefer polycarbonate, which is lightweight and does not break easily. There are also different lens coatings available for convenience (i.e. anti-reflective coatings), but they are not required.”
Goel notes that the American Academy of Ophthalmology does not recommend blue light blocking coatings or lenses because “there is no scientific evidence to suggest that blue light blocking glasses help reduce eye strain.” Instead, take breaks from activities near work and use eye drops if necessary. If you continue to experience symptoms, consult an ophthalmologist.
According to Reed, most people choose from the following three lens materials for their reading glasses:
- CR-39 plastic lenses: Affordable, lightweight, and offering good optical clarity, making them a popular choice for basic reading glasses.
- Polycarbonate lenses: Lighter and significantly more impact resistant than CR-39 plastic, making it a safer option for people who tend to drop their glasses or want something more durable.
- High index plastic lenses: Thinner and lighter than other materials, they are a good choice for people who need a stronger prescription but want to avoid thick, heavy lenses.
“For most reading glasses, especially for casual or indoor use, CR-39 plastic works well,” says Reed. “If you need additional durability or prefer thinner, lighter lenses, polycarbonate or high-index materials may be better suited. Your doctor of optometry can help recommend the best lens material based on your specific needs.”
Reed adds that not all lens materials and coatings are equal. That’s why it’s important to consult your eye doctor to make sure the reading glasses you choose are right for you.
Style
One of the most fun parts of shopping for glasses is finding a frame that matches your personal style and fits your face shape. When buying glasses online, pay attention to the material, color and width.
Price
Reading glasses can range from affordable to expensive. For example, if you want a pair of designer reading glasses, be prepared to spend upwards of $100. If you tend to lose your reading glasses, you may want to purchase cheaper pairs so you can keep several on hand.
“The price of glasses does not necessarily reflect quality; the real question is whether someone finds off-the-shelf reading glasses useful or whether they need customized reading glasses to meet their visual needs,” says Goel.
“In general, spending more on frames doesn’t mean you’ll get better quality glasses. You don’t need designer frames to have a good pair of glasses. For prescription lenses, such as bifocals, trifocals, or progressive lenses, an optician will help you select good lenses that best suit your visual needs. A personalized assessment of visual needs is an added value that online sellers often lack.”
Additional coatings
You can get reading glasses whose lenses are treated with anti-blue light, anti-glare, and polarizing coatings. But note that you will probably have to pay extra for this.
Shipping and Returns
If you buy your reading glasses online, you probably won’t be able to try them on before you buy. Therefore, make sure the company has a return and exchange policy that you can work with. As for shipping, if you need your reading glasses ASAP, you’re better off going with a company that offers express or overnight shipping.
