The difference between cheap eyeglasses near me and expensive glasses is mainly reflected in the following aspects:
Functional differences: Expensive lenses typically have more functionality, such as color changing, anti-blue light, multifocal, etc., which can provide a more comprehensive visual experience. Cheap lenses may only meet the most basic requirements, with significant differences in optical performance and transmittance.
Precision and Comfort: Expensive lenses typically have higher ... moreThe difference between cheap eyeglasses near me and expensive glasses is mainly reflected in the following aspects:
Functional differences: Expensive lenses typically have more functionality, such as color changing, anti-blue light, multifocal, etc., which can provide a more comprehensive visual experience. Cheap lenses may only meet the most basic requirements, with significant differences in optical performance and transmittance.
Precision and Comfort: Expensive lenses typically have higher precision and comfort as they may use more advanced technology and materials. Cheap eyeglasses near me lenses may have issues such as bubbles and scratches, and wearing them for a long time may feel dry and uncomfortable.
Brand and quality: The price of brand lenses is transparent, with a nationwide unified retail price, while miscellaneous lenses may have quality issues. First-tier brands such as Cai Sixuan and Yishi Lukang have significant advantages in wear resistance indicators and imaging quality, while second-tier brands such as Mingyue Fen and Wanxin Fen have little difference in quality compared to first-tier brands.
Refractive index π and Abbe number π: The higher the refractive index, the higher the price of the lens, but the higher the refractive index, the smaller the Abbe number, and the worse the transmittance. Abbe number is an important indicator for measuring the clarity of lens imaging. The smaller the Abbe number, the greater the lens dispersion and the worse the clarity. Therefore, selecting the appropriate refractive index and Abbe number is crucial for ensuring the quality of the lens.
Subjective wearing experience: Expensive lenses typically perform better in terms of imaging quality, visual comfort, etc., providing a clearer and more transparent visual experience.
Differences in material properties: The material properties of lenses are also an important factor affecting price. Lenses of different price ranges have different refractive powers and indices. For patients with higher degrees, it may be necessary to choose lenses with higher refractive indices to make the resulting glasses lighter and thinner, but this also means higher prices.
In summary, there are significant differences between cheap eyeglasses near me and expensive glasses in terms of functionality, accuracy, brand quality, imaging clarity, wearing experience, and material characteristics. When choosing glasses, one should choose the appropriate lenses based on personal needs and budget.
