What the index means of lenses?

The Lens Index number (1.50, 1.57, 1.53, 1.59, 1.61, 1.67, or 1.74) refers to the degree of refraction the lens provides. This means how much the light that enters the lens is refracted (bent) as it passes through the lens. Lens Index is also related to the thickness of the lens. The higher the index, the thinner the lens will be. People with higher prescriptions should choose high-index lenses.

What can I do if my frames don't fit perfectly?

Email or chat with them within the first 30 days after you've received the glasses. If the frame is defective, they can send you a new one or give you 100% refund. If you want to reorder a new pair of glasses in the correct size, and they'll explain how to make sure the next frame you get will fit you perfectly.

Why I feel uncomfortable after receiving my new glasses?

Some people may experience a distortion of their peripheral vision after receiving a new glasses prescription. This is a fairly common occurrence that can be a result of the adjustment period as your eyes get used to the new prescription. This type of peripheral vision distortion can often occur if the new glasses are of a higher prescription or the frames are larger than what you are used to. Glasses focus on the section of the visual field that is right in front of you, in order to help correct your vision and perception. If you've been wearing glasses for a long time, your brain gets used to this and can find it hard to adjust if the prescription is changed. In addition to this, hi index lens materials can also cause a distortion of peripheral vision. These types of lenses are thinner and lighter than normal, which means the back surface of the lens is placed further away from the natural curve of your eye. This distance can in turn affects your peripheral view. Another type of lens that can cause peripheral distortions are multifocal lenses. These lenses are designed to provide clear vision in certain areas. Towards the edges or sides of multifocal lenses, there are peripheral distortions.
