While buying prescription glasses, the most important factor to consider apart from the prescription is the lens type. Individuals can choose hi-index, polarized, photo-chromatic or polycarbonate lenses depending upon their wants and preferences.
Apart from these factors, another key feature that is very important to consider is the lens coating. Lenses can comprise of one or more coatings that allow better vision quality and an overall better eye wear experience.
Buyers can also choose the coatings that they want. The different lens coatings available are as follows:
1. Anti-reflective Coating: Anti reflective coating as the name suggests helps in shielding the internal and external reflections on a lens. Strong glares and reflections can cause great strain to the eyes and hence must be shielded in every possible way. Thus this ensures that not only do you get a much clearer vision but also reduce the strain caused to your eyes due to the reflective glares. Especially at night time the anti reflective coating shields the glare coming from car lights thereby making driving at night easier. Anti reflective coating ensures that the glasses look slender and attractive.
2. Scratch-resistant Coating: As the name suggests, scratch-resistant coating is important in making the lens scratch-proof and protect it from damage. Thus, in the event of pair being dropped against a hard surface, the scratch resistant coating minimizes the damage done to the lenses. These days almost all prescription glasses consist of this coating.
3. Ultraviolet Coating: Our eyes are extremely sensitive and prolonged exposure to UV rays can cause harmful damage leading to ailments like cataract and macular degeneration. Thus, it is extremely critical to protect your eyes against UV rays. Usually an integral component of sunglasses, UV coatings has also become a mainstay of prescription glasses. Most prescription sunglasses these days comprise of UV400 coatings.
These are the most prominent lens coatings that ensure a clear and strain-free eye wear experience. It is always recommended that buyers ensure that their glasses are treated with these coatings before they make the purchase.
These coatings not only provide better vision but also play a vital role making the frame more durable.
