Would It Be Better to Use Contact Lenses Interchangeably with Frame Glasses?

Contact lenses are favored by more and more patients with refractive errors for their unique advantages such as comfortable wearing, wide field of view, and true and natural vision. However, after some patients wear contact lenses, they dismissive of the glasses frames for myopia dismissively, thus ignoring that frame glasses have the advantages that contact lenses cannot replace. This approach is not advisable, the best way to wear it should be to wear contact lenses and frame glasses alternately.

The Advantages And Disadvantages of Contact Lenses And Frame Glasses

The advantage of frame glasses is that they are more convenient to wear and the price is relatively cheap. The disadvantage is that the correct range of frame glasses is relatively limited. Moreover, there is a distance between the frame glasses and the eyeballs. Wearing frame glasses will easily cause the visual field to become smaller, especially for myopia with a higher degree, the visual field becomes smaller. Common frame glasses are blue light frames, full lens reading sunglasses and eyekepper computer glasses.

Contact lenses are also called contact lenses. The advantage is that it is more convenient to wear and does not affect the appearance of the eyes. The disadvantage is that it covers the surface of the cornea and conjunctiva for a long time. If the method of wearing is not correct, it may cause local complications, such as conjunctivitis, keratitis or corneal epithelial damage.

Reasons for The Interchange of Contact Lenses And Glasses

First of all, alternate wearing can reduce the complications of contact lenses and extend the service life of the lenses. Since contact lenses directly cover the cornea, which is the important refractive tissue of the eyeball, and 80% of the oxygen required by the cornea comes directly from air, after wearing contact lenses, the absorption of oxygen is reduced to varying degrees. At the same time, it will interfere with the metabolic activity of the cornea and the normal excretion of tears, so that the defensive function of the eyeball will decrease, and it will easily induce some eye diseases.

In particular, patients who wear contact lenses overtime will cause the lens to mechanically rub the surface of the cornea and conjunctiva for a long time, and the cornea will be hypoxic under the lens for a long time, which can damage the corneal epithelium, increase secretions, and be broken down and metabolized. The protein is attached to the lens. Over time, this will not only cause eye diseases due to prolonged hypoxia of the cornea, but also affect the service life of the lenses due to the failure of timely cleaning. Therefore, contact lenses have strict requirements on hygiene and daily care.

In contrast, framed lenses overcome the shortcomings of contact lenses, such as easy removal and wearing, simple care, and freedom from environmental factors. And because it is worn outside the eyeball, it will not interfere with the normal metabolism of the eye and is not easy to cause eye diseases. The above frame mirrors including folding reading glasses, anti glare blue light glasses and screen glasses for kids have their distinct advantages.

Secondly, alternate wearing can improve the comfort of wearing a framed lens after the contact lens is stopped. Since the center thickness of the contact lens is only 0.02mm～0.2mm, the curvature changes slightly and directly covers the cornea, so there is generally no visual field limitation, prism effect, dispersion, and aberration of the frame lens. Once there is a need to stop wearing contact lenses and wearing myopia frames, it will be difficult for patients to adapt in a short time due to a series of sudden changes such as the narrow field of view, the prism effect, dispersion, and aberration adjustment.

Computers are almost inseparable for study, work, life, and entertainment. The computer is a close-range luminous body, long-term use will bring fatigue to the eyes. In view of this situation, it is recommended to choose glasses with frames, such as computer rays protection glasses, anti blue ray eyeglasses and anti blue light prescription glasses. Blue gradient lens sunglasses is also an excellent choice for outdoor activities.
