G.DIA Colored Contact Lenses

G.DIA means ‘Graphic Diameter’, which is the size of the colored segment of the lens.  Graphic diameter refers to the even distance across the iris – the usual person’s graphic diameter falls inside 11.6mm to 12mm. If you’re quick to find out your G.DIA, you can contact to your nearby optician.

Depending on your own G.Dia, choose a pair of lenses that matches it. As a guideline, select a pair of lenses that is around the 11.9mm range.

When selecting contact lenses for vision correction, there are various important factors to consider. One of them is an ideal fit, which is helped generally by ensuring you request the specific solution your optician has given you: this will make sure that the contact lens fits well on your eye.

Wearing ineffectively fitting contact lenses can harm the eye and create issues like obscured vision, headaches, and eye strain. The G.diameter and base curve of a contact lens are two measurements that influence how well they fit your eye.

Which G.DIA contact lens should I choose?

There are differences between people, but the average diameter of people’s iris is 11-12mm. G.DIA is created by considering people’s eye movement and the beauty effect that makes their eyes greater and clear. So based on the average diameter of the iris -

• DIA 11.9mm-13.4mm appears Natural
• DIA 13.5mm-13.9mm appears somewhat noticeable.
• DIA bigger than 13.9mm appears very noticeable.

WHAT IMPACT DOES G.DIAMETER HAVE ON COMFORT?

Contact lenses are not one-size-fits-all. Having the right fit is fundamental for clear vision and long-term comfort and fulfillment with your lenses. The Graphic diameter and base curve are important factors in determining what the optimum fit is for you.

A well-fitted lens covers the cornea appropriately and stops dryness due to an exposed cornea. Dry eye is a typical reason for eye distress with contact lens use, and a well-aligned lens does not produce any edge strain that can prompt discomfort. When the base curve and contact lens diameter are appropriate, there is satisfactory tear trade from under the lens surface, which helps clear out debris. All these variables add to your lenses being comfortable to wear and preventing eye damage and strain, in this way advancing by and large eye wellbeing.
