Get an Expert Advice for Your Eye Glasses Lens

In an eye test, the eyes’ visual acuity and overall health are tested using special
instruments (for example, to spot symptoms or signs of eye disease). Contact
lenses and glasses can be recalled or replaced by an optometrist. They will also
educate you on the various facets of your eye health and help you manage them.
It is common for optometrists to prescribe topical eye medications for allergies,
infections, and glaucoma.

Specific considerations that must be remembered when choosing
lenses:

According to a professional optometrist, the rule of thumb is that the frame
should not be too short or too broad for your face. In small frames, the field of
view extends beyond the lenses, enhancing the prescription.

• Materials for the lens:

Glass Lens: Previously, all eyeglass lenses were made of glass in the early days of
vision correction. The heavy nature of glass lenses makes them a poor choice for
optics. They can be quickly broken, causing severe eye damage or even eye loss.
Glass lenses are no longer used in eyeglasses for these reasons.

In 1947, lightweight plastic eyeglasses were produced for the first time with
plastic lenses. The lenses were constructed from CR-39 plastic polymer.

Polycarbonate lenses: To protect lenses, polycarbonate lenses have been
introduced. Polycarbonate lenses became more and more popular and continued
to be widely used later that decade and in the 1980s.

High-index plastic lenses: A range of lens makers have launched high-index
plastic lenses in the last 20 years in response to the demand for smaller,
lightweight eye lenses.

• Proper alignment of the lens:

The middle orientation that lets you see clearly is critical when it comes to the
correct selection of frames. An eyeglass lens with a glass core is in direct
contact with the eyes. This allows you to see better without straining your
eyes. Glass lenses are concave on the inner surface and convex on the outer
surface, so the middle of the lenses is often more comfortable to look at.
Distorted frames or frames that tilt to one side of the eye may create strain
and raise the optometric defect in some cases.

• Choose a lightweight frame always:

This is critical since heavy frames typically cause headaches or eye exhaustion.
Often, they fall off their noses. It doesn’t mean that you will stick all your life to
cardboard boxes. Titanium panels, compared with other types of panels, are
considerably thinner and thicker.
