How to choose the right contact lens

There are many factors to choose the right contact lens for you, such as how often you are going to wear the lenses, your prescription. the curvature and health of your eyes. Our optometrists at Evershine Optical will be here to help you .

Types of contact lenses

There are 2 types of contact lenses, soft and rigid contact lenses. Many often goes for soft contact lenses first. Unless they are deemed to be not suitable for soft contact lenses, eg, due to dry eyes, poor vision, high prescription, then they will opt for rigid contact lenses.

The image below shows soft and RGP contact lenses. Soft contact lenses are bigger and softer while RGP contact lenses are smaller and more rigid.


Modality of the lens refers to whether you want the lens to be daily disposable, bi-weekly disposable or monthly disposable. This depends on how often you want to wear the contact lenses. Usually if you want to wear only 1-2 days per week, daily disposable will be recommended. If you are wearing them more than 3 days per week, bi-weekly or monthly disposable will be recommended. However, using bi-weekly or monthly disposable means you will need to clean and store the contact lenses at a regular basis or when you use them.

Lens material

The common contact lens materials are Hydrogel and Silicone Hydrogel. Silicone hydrogel is a more oxygen permeable material, which allows more oxygen entering your eyes as compared to Hydrogel. This increased oxygen permeability may reduce the risk of contact lens-related eye problems. However, contact lenses made from silicone hydrogel is usually more expensive than hydrogel ones. Depending on your eye health, wearing hours and budget, our optometrists will recommend you accordingly.

Size of contact lenses

Contact lenses comes in different size which are known as base curve and diameter. These can affect how well the contact lenses are staying on your eyes, whether are they too loose or too tight. If they are too loose, the lens might drop out when you move your eyes. If they are too tight, you might feel uncomfortable after 1-2 hours of contact lens wear. A contact lens consultation is recommended to asses the curvature of your eyes to determine which base curve is suitable for you.

Why is it important to have a contact lens consultation

Astigmatism and multifocal contact lenses are different from normal single vision contact lenses.

For toric contact lenses that corrects astigmatism, the axis of rotation will affect your vision. Even if the axis of the contact lens is the same as your spectacle prescription, the rotation will affect how well you can see. A compensation of the axis will be needed for you to have clearer vision. Thus, the axis of your contact lens is not necessary the same as your spectacle prescription, which is why it is important to have a contact lens consultation.

For multifocal contact lenses, even though the prescription for the contact lenses is theoretically correct, you might still experience blur distance vision but clear near vision, clear distance vision but blur near vision or blurry distance and near vision. The prescription will then need to be adjusted accordingly.

Therefore, it is important to go through a contact lens consultation especially for astigmatism and multifocal contact lenses so that the optometrists can adjust the prescription before the problems arise after you brought home the lenses.
