Cheaters glasses are non-prescription, over-the-counter magnifying spectacles that correct age-related presbyopia for close-up tasks like reading, without requiring an optometrist exam.
For the full breakdown, see our best Cheaters Glasses guide.
The term is US slang from the 1920s — “cheaters” because they bypass the need for a full prescription and an eye doctor visit. They are simply reading glasses sold at drugstores, convenience stores, and online, typically costing a fraction of prescription eyewear. They work for short-duration tasks like reading menus, threading a needle, or checking a phone screen, but they are not a substitute for prescription lenses or an eye exam.
How Cheaters Glasses Work
Cheaters use simple spherical magnifying lenses with identical power in both eyes. Standard OTC versions offer basic spherical magnifiers, while premium versions may feature aspheric lenses that provide even magnification across the entire lens. Some modern versions include anti-reflective coatings, blue light filtering, or adjustable-focus lenses. Design variations include full-frame readers, magnified lower lenses with clear upper sections (mimicking bifocals), and progressive lens options for focal distances of 12–18 inches.
Because both lenses are identical, they cannot correct astigmatism or different prescriptions between eyes — those issues require custom prescription glasses from an optometrist.
Choosing the Right Strength
Magnification levels range from +1.00 to +3.50 diopters. The Cleveland Clinic recommends selecting the lowest power that allows comfortable reading at your preferred distance. Here is how to pick the correct strength:
- Arm-Length Test: Hold reading material at arm’s length and try different magnifications until the text sharpens at a comfortable distance.
- Age-Based Estimate: +1.50 is common for ages 45–50; strength generally increases with age.
- Frame Fit Check: Ensure frames do not extend beyond your cheekbones — oversized frames create visual distortion with the magnified lens.
- Trial: If available in-store, test multiple strengths before buying to confirm comfort.
Using a strength that is too high causes headaches, eye strain, and temporary blurry vision. The lowest effective power is always the correct choice.
When Cheaters Work — and When They Don’t
Cheaters are designed for short-duration, close-up tasks — reading a book, sewing, or browsing a tablet. They are ideal for the 1.8 billion people the World Health Organization projects will have presbyopia globally by 2030, particularly those over 40 whose lens rigidity makes near vision difficult.
They are not designed for all-day wear, distance vision, or complex vision needs. Common mistakes include using them while driving (dangerous, as the focal length is fixed for close range) or relying on them instead of getting an eye exam. The FDA classifies cheaters as magnifying spectacles and notes the term can mislead consumers about their corrective capabilities. Overuse causes temporary discomfort, but they do not permanently damage your eyes — incorrect strength simply creates temporary strain.
Limitations to Know
Because cheaters are mass-produced with identical lenses, they lack customization for:
- Astigmatism (requires cylindrical correction)
- Different prescription strengths between your left and right eye
- Complex vision needs like prism correction or progressives for intermediate and distance
Some premium frames can be fitted with custom prescription lenses by an optician, bridging the gap between OTC and prescription eyewear. Otherwise, relying on cheaters for daily use may delay necessary medical care — a comprehensive eye exam every two years is recommended for adults. According to the Merriam-Webster dictionary, the term “cheater” itself dates to 1925 and originally meant “sunglasses or dark glasses” before shifting to its current meaning of reading glasses.
FAQs
Can cheaters glasses damage your eyes?
No, using cheaters does not cause permanent eye damage. Wearing the wrong strength can cause temporary headaches, eye strain, or blurry vision, but these symptoms resolve once you switch to the correct power or stop using them.
What strength cheaters do I need?
Most people over 40 start with +1.00 to +1.50. An arm-length test — holding reading material at arm’s length and trying different magnifications until the text sharpens — gives your best starting point. The lowest power that works comfortably is correct.
Are cheaters the same as prescription reading glasses?
No. Cheaters have identical magnifying power in both lenses and cannot correct astigmatism or different eye prescriptions. Prescription reading glasses are custom-made for your specific vision needs by an optometrist after an exam.
