Why are the glasses blurry? There are many reasons why the lenses of glasses are blurry, which can lead to problems with the film layer during use, as well as other situations that can cause blurring of the discount prescription glasses lenses.

Lens film detachment: High temperature, acidic liquids, corrosive gases, etc. can all cause the lens film to detach, including placing glasses in the car, taking a bath with glasses, or wearing glasses around combustible materials.

Scratches on the surface of the lens, especially in the central area of the pupil, can directly affect clarity. Most of the scratches are caused by long-term improper use, including improper wiping techniques and tools, as well as small surface scratches caused by improper placement of the lens and downward-facing wear.

Poor cleaning of oil stains: Due to the lack of cleaning on the surface of the lens, prolonged uncleaning, or only cleaning of dust, the oil stains on the surface of the lens are not carefully cleaned, resulting in a decrease in clarity and glare that affects vision.

Yellowing of lenses: The discount eyeglasses online lenses that have been used for too long exceed their lifespan, or have a reduced lifespan during use can cause discoloration, yellowing, reduced transparency, and affect clarity.

Environmental impacts: sandstorms, haze, underground dust, and special working environments can all affect the surface clarity and lifespan of lenses.

In such cases, it is necessary to replace the cheapest eyeglasses online lenses on time to avoid problems with the lenses, which may affect the comfort and clarity of wearing glasses and affect vision and visual function.
