What Kind of Glasses is Right for Strong Prescription?

      more and more young people, even children, wear thick glasses and become high prescription eventually due to the myopia appearing among more and more younger age.  Glasses have been a necessity for strong prescription. People with strong prescription cannot even work or live normally without glasses. So, how to choose suitable glasses for them?

   Firstly, what is strong prescription? Strong prescription refers to the phenomenon that the prescription of myopia is 600 degrees or more, with the axis lengthening. People need to wear glasses to obtain normal and clear images for this. However, the lens thickness is related with the prescription, so, how to make the glasses as light as possible while ensuring the clarity has become the primary concern.

     VlookOptical will give some tips for you to make your glasses lighter, this tips is also availabel in Frame Selection:

    1. Light frame

    The weight of frame is an important factor affecting the comfort of glasses. When choosing frame, we need a healthy, safe, comfortable, reliable, stable material which is harmless to the skin. And it should be light, firm and not easily deformed.

    For highly prescription people, priority should be given to titanium, thin acetate and TR90 materials, which are generally lightweight and durable. In addition to lightweight, titanium frame, in particular, also has good compatibility with the skin and it will hardly cause skin allergies. Besides, it  is also not easy to deform because of its high strength.

    2. Frames with smaller frame widths

    The thickness of prescription lenses is mainly reflected in the horizontal direction of the spectacle frame. In many cases, the edge of strong prescription lenses is thicker, which is most easily detected from the side and affects the appearance. When the frame’s total front width is suitable, the smaller the frame width is, the thinner the processed lens is. In this way, the temporal rim thickness of the lens can be reduced to the greatest extent, and the overall appearance of the glasses can be improved.

    3. A full-rimmed frame

    It is known that the lenses with strong prescription are thicker, choosing rimless or half-rimmed frames will expose the thickness of lenses. And the frame is easily deformed after a long time, resulting in changes of the glasses center and the axis of the lenses and affecting the ability of correcting visual acuity. Therefore, VlookOptical recommend to choose full-rimmed glasses as far as possible for those people with strong prescription.

    Lens selection refers to the following aspects:

    1. Light lenses

    The higher prescription power is, the thicker the lenses is and the greater the pressure to the nose bridge is. Hence, VlookGlasses suggest to choose lighter resin lenses to relieve the pressure.

    2. Aspheric high refractive index lenses

    Aspheric lenses with the same refractive index are thinner and lighter than spherical lenses. Less optical distortion ensures the lowest aberration at the edge, and a clearer and more natural view. But the aspheric price is higher than spherical price, the higher refractive index is, the more expensive price is. People can choose their index based on their own economic situation. It’s better to choose high refractive index aspheric resin lenses. So VlookOptical recommends to select the lens with refractive index of 1.67 or 1.74 for those with strong prescription to ensure the lenses lighter.
