I attempted five different sets of lens, with three coming from a reputable opticians. Unfortunately, none of them were able to meet my specific requirements, and wearing them actually worsened my eyesight. I must clarify that I do not recommend using lenses without a prescription. However, I made some minor adjustments to the lens strength to cater to my needs, and I must say that they are truly exceptional. These lenses provide me with the safety and functionality required to perform my job effectively. I am sincerely grateful for this solution.
