Classic reading glasses in a transparent plastic case. Reading glasses are designed to correct presbyopia, a natural age-related condition that affects the eyes' ability to focus on near objects. The lenses are clear, with a plastic frame, lightweight and comfortable.

The "half-frame" glasses make it easier to shift your gaze from near to far.

The numbering of reading glasses refers to the diopter (refractive power) required to correct near vision. It is expressed in positive degrees (+) and is determined by the prescription from an optician or ophthalmologist:

• +0.50 to +1.00: For mild presbyopia or for users just starting to have difficulty with near vision.
• +1.25 to +2.00: For moderate presbyopia, usually for ages 45-55.
• +2.25 to +3.00: For more advanced presbyopia, usually for ages over 55.
• +3.25 and above: For severe cases where presbyopia has progressed further.

The exact numbering is determined by refractive testing from an optician or ophthalmologist. You can try glasses with different measurements to see which suits you best. The numbering may differ between the two eyes (e.g., +1.5 in the right, +2.00 in the left).
