Strong Prescription, Which Lenses Do I Need? -

People nowadays, even children and young one, easily tend to get high prescription lenses sue to excessive digital device usage. However, when we ought to wear them, we must make sure that we are using the best and great quality ones! Definitely, the correct choice would be a thinner, lighter lenses as well as eyeglasses that are as good-looking and relaxed as possible.


Physicians recommend thinner & lighter high-index lenses that are especially suggested to those having a strong eyeglass prescription, either for near or farsightedness. Knowing the truth that most of the wearers are nearsighted, they require helpful lenses that are thin in the midpoint but denser at the edge of the lens. It is therefore for sure, the stronger the prescription, the denser the edges!




These days, many trendy & stylish frames are made of different types of material with rims thinner than lens. Some well-known rimless mountings show that the boundaries of the lenses are fully visible. No matter in any scenario, the lens edges are very noticeable and denser edges can diminish from the look of your glasses.


How Strong prescription Vary From Normal Lenses?


The lenses of glasses precise refractive inaccuracies by refracting the light as it pass from the lens. The total quantity of light-bending capability needed to deliver decent vision is designated on the lens prescription prescribed by the eye specialist.





A middle index prescription such as 1.57 is sufficient in the -2.00 diopter situation. Also, note that you may probably not wear eyeglasses for more than sometime, if you are looking to correct vision enhancement.


Once someone is near to -5.00 diopters, shifting its index above to 1.61 is an ideal notion. So, if you are prescribed to over -6.00 diopters, then 1.67 index lens is a sensible upgrading.


High-Prescription Lens Choices


There is surely a vast range of thin, strong index eyeglass lenses available these days in online stores depending on how efficiently they bend light. The light-refracting capacity of eyeglass lenses is specified by "index of diversion" of the lens. This index is the proportion of light-speed when it passes through air to the lens material. This speed decreases more as it goes through the lens material.



Thus, lenses that curve light more proficiently possess a greater index of diversion than those that curve light less capably. Lenses that have greater refractive index are slighter than same power formed of materials of inferior refractive index. Hence in brief, the greater the refractive index, the thinner its lens will be.


AR Coating: A Perfect Companion for High-Index Lenses

Although any lens block some amount of light passing through it but when you especially order Anti-reflective (AR) coating to its surface, it surely reflects back light from its surface. This blocks interruptions and raises the precision of night vision.

For your superlative visualization and presence, it's a virtuous idea to have an anti-reflective lens coating (AR coating) applied to high-index lenses. AR-coated lenses reflects back up to 99.5 percent to the eye for greatest results.
